If you're a product manager responsible for authentication or work in identity, you've likely sat in meetings where leadership asks: "Why is our conversion rate stuck?" The usual suspects get blamed: ad spend, page load times, checkout UX. But when you dig into the data, there's a step in the funnel that's harder to diagnose: the login.

The problem is that most analytics stacks treat authentication as a binary event:

• logged in
• not logged in.

They don't capture the friction in between: the user who tried three passwords, got frustrated and bounced. The one whose SMS code arrived 45 seconds too late. The returning customer who couldn't remember if they used "Sign in with Google" or created a password.

This blind spot is expensive. Cart abandonment rates average around 70% and a significant chunk traces back to authentication friction. But unlike checkout abandonment (which every e-commerce team obsesses over), login drop-off often goes unmeasured and therefore unfixed.

The impact compounds: every failed login is wasted CAC, reduced Customer Lifetime Value (CLTV) and a customer who may switch to a competitor with a smoother experience. If you can't instrument it, you can't improve it. And if you can't prove the ROI, you can't get engineering resources to fix it.

Before diving deeper, consider this: If reducing login drop-off by a few percent means +6 figures in annual revenue for a large e-commerce company, what does it mean for yours?

If you cannot fill in that table - or worse, if that data does not exist in your analytics stack - you have identified the first symptom of a deeper problem: you are flying blind on authentication.

Every authentication step is a tax on user intent. The question is: do you know how much you're charging?

Consider what happens when a returning user wants to complete a purchase:

• They try their usual password. Wrong.
• They try a variation. Wrong again.
• Now they're at a decision point: reset password (5+ minutes of friction) or abandon cart (2 seconds).

For most users, abandonment wins. And your analytics just shows a bounce, not the root cause.

This "login tax" compounds at the worst possible moment: checkout. The user has already invested time browsing, comparing, adding to cart. They're ready to pay. Then authentication friction hits and cognitive load exceeds motivation.

What this article covers: This is a practical breakdown of the six authentication failures that kill conversion and how to diagnose them in your own funnel. Each section includes what to measure, what the root cause typically is and what the fix looks like. The goal is to give you the data to build a business case for authentication investment and a roadmap to actually execute it.

How to detect it: Track the delta between "login modal opened" and "login successful." If you're seeing 20%+ drop-off before authentication completes, this section applies to you.

Why it matters: This is the highest-intent moment in your funnel. Users who reach login have already decided to engage: they're one step from conversion. Losing them here has the worst ROI impact of any funnel stage.

The "forced registration" pattern is one of the most aggressive conversion killers in e-commerce. Unlike browsing - where users can freely explore products - checkout is where the login wall appears. The user has already invested time: browsing, comparing, adding to cart. They are ready to pay. Then the site demands account creation before they can complete the purchase. This timing is catastrophic. Users view their email address, identity and time as currency. Forcing them to "spend" this currency - creating and managing yet another password - at the exact moment they want to give you money creates maximum friction at maximum intent.

Compounding this issue is the lack of "alternative paths" or "guest flows." E-commerce data reinforces this: 37% of users abandon their cart because they are required to create an account. The absence of a "Guest Checkout" option forces a commitment that the user is not ready to make. While businesses desire account creation for retention, marketing re-targeting and data profiling, forcing it prematurely backfires, resulting in zero data and zero revenue. A user who buys as a guest is a customer. A user who leaves because they didn't want to create an account is a lost statistic.

Many sites attempt to mitigate this by offering account creation after the purchase, but the damage is often done by the initial prompt. Best practices now dictate asking for minimal information in the first step - perhaps just an email or a social identifier - and using progressive profiling to collect additional data only when necessary and when trust has been established. Yet, legacy systems often remain rigid, demanding a full dossier (First Name, Last Name, Phone, Address, Mother's Maiden Name) at the door.

The "weak alternative path" also manifests in the poor implementation of social logins (federated identity). Social login (e.g. "Sign in with Google," "Continue with Apple") is theoretically a friction-reducer, as it eliminates the need to create a new password. However, if these buttons are hidden below the fold, rendered in a way that suggests they are secondary or inferior options or if they lack the appropriate "scopes" (asking for too much data), the user is funneled back into the high-friction password path.

Furthermore, the "NASCAR effect" - where a screen is cluttered with logos of every possible identity provider (Google, Facebook, Apple, etc.) - can lead to decision paralysis. Conversely, offering only one option that the user doesn't utilize (e.g. offering only Facebook login when your customers primarily use Apple devices) creates a dead end. The design choice often stems from a misguided desire to "own the credential" (forcing a local password), which inadvertently increases abandonment by pushing users toward the path of most resistance.

On mobile devices, where screen real estate is limited and typing is prone to error, the forced login wall is even more deadly. Filling out a multi-field registration form on a smartphone keyboard is a high-friction activity. If the "Sign Up" button is not easily accessible via a "One-Tap" solution or if the form does not support autofill attributes correctly, the abandonment rate spikes significantly compared to desktop. The gap between mobile traffic (high) and mobile conversion (low) is often explained by the sheer difficulty of navigating these login walls on a 6-inch screen.

How to detect it: Pull your password reset rate as a percentage of total login attempts. If it's above 10%, password fatigue is actively hurting your returning user conversion.

Why it matters: Password resets are a proxy for frustrated users. Every reset represents a user who wanted to engage but couldn't. Some complete the reset flow; many don't. Either way, the purchase intent has cooled.

The most tangible metric of password fatigue is the password reset rate. It is a proxy for user frustration. When a user returns to a site to make a purchase and they are greeted with an "Incorrect Password" error, they enter a state of friction. They likely try one or two variations of their standard password. If those fail, they are faced with a binary choice: initiate the password reset flow or abandon the task.

~19% of users abandon carts specifically because they forgot their password and gave up on reset. The reset flow isn't a simple click. It's a multi-step context switch that breaks purchase momentum:

1. Click "Forgot Password."
2. Enter email address.
3. Wait for the email (latency variable).
4. Open a new tab or app to check email.
5. Find the email (often buried in Promotions or Spam).
6. Click the reset link.
7. Create a new password that meets obscure complexity rules (e.g. "Must contain one uppercase, one number, one symbol and no consecutive characters").
8. Confirm the new password.
9. Return to the login screen.
10. Enter the new credentials.

Each step is a drop-off point. By step 5 (finding the email in spam), you've lost a significant chunk of users. Even those who complete the flow associate the frustration with your brand - not a great state to be in right before asking for payment.

Moreover, the "security" rules enforced during these resets often exacerbate the pain. Nearly 50% of users say they would abandon a website if told their new password cannot be the same as an old one. This "history check" feature, intended to improve security by preventing the rotation of compromised passwords, blocks the user's primary coping mechanism for password fatigue: reuse. While password reuse is insecure (52% of users admit to reusing passwords), blocking it without offering a viable, low-friction alternative (like passkeys) simply blocks the user. The user is left trying to invent a new password on the fly, which they will inevitably forget, ensuring the cycle repeats next time.

From an operational perspective, the cost of these resets is astronomical. Forrester estimates that a single password reset can cost a business $70 in helpdesk resources if it requires human intervention. Even self-service resets consume server resources, email delivery costs (transactional email providers charge by volume) and potential SMS costs. For large enterprises, this operational drag runs into the millions of dollars annually.

However, the "invisible" cost - the churn of frustrated returning users - is the true killer of conversion. These are users who wanted to engage, who had high intent, but were locked out by the very keys meant to secure them. The friction of the password reset loop is a self-inflicted wound on the conversion funnel, turning loyal customers into churn statistics.

Ironically, the friction of passwords leads to weaker security. Because users are frustrated, they resort to dangerous behaviors: writing passwords down, using "Password123" or sharing credentials. 46% of US consumers fail to complete transactions due to authentication failure and this failure drives them toward competitors who might offer a seamless login experience. The password has become the primary vector for both security breaches (via credential stuffing) and conversion breaches (via abandonment).

How to detect it: Track OTP request → OTP submitted → OTP success. Also measure time-to-submit. If you're seeing >5% failure rate or >30 second average time-to-submit, SMS delivery is a conversion problem.

Why it matters: SMS OTPs swap a memory problem (passwords) for a delivery problem. The failure modes are invisible to most analytics: you see a drop-off, but not the user staring at their phone waiting for a code that never arrives. Worse: SMS costs scale with usage, so you're paying for friction.

The fundamental flaw of SMS authentication is its reliance on the telephony network (SS7) - a system never designed for real-time, high-security identity verification. The delivery of an SMS code depends on a complex, opaque chain of aggregators, carriers and international roaming agreements. A failure at any single point in this chain results in the user staring at a screen, waiting for a code that never arrives.

A 2014 Ponemon Institute study (reported via tyntec) found that a significant portion of OTPs failed to arrive, with factors like invalid numbers contributing to high non-delivery rates. While SMS infrastructure has improved since then, deliverability remains highly variable depending on provider, region, carrier relationships and routing configuration. Major messaging providers like Twilio emphasize that delivery rates fluctuate based on these factors - there is no single global benchmark. Even in well-optimized scenarios, a failure rate of just 5% at the authentication step is a catastrophe for conversion. If 5 out of 100 users are locked out because their carrier blocked the short code, the network was congested or they are in a building with poor signal, that is 5% revenue churn built into the infrastructure.

"Time to Delivery" is a critical, yet often unmeasured metric. In the high-speed context of a digital transaction, a delay of 30 seconds feels like an eternity to a user. If the code arrives after 60 seconds, the user has likely already grown impatient and clicked "Resend Code." When the first code finally arrives, the user enters it, only to be told it is invalid because the second request invalidated the first. This creates a "race condition" loop of failure where the user enters valid codes that are rejected by the server logic, leading to confusion, rage-quits and support tickets.

The reliability of SMS is further compromised by the rise of SMS pumping fraud (also known as toll fraud), where bad actors generate artificial traffic to harvest share-of-revenue from premium rate numbers. In response, carriers have implemented aggressive spam filtering algorithms. Legitimate transactional OTPs are frequently caught in these filters, especially for international users or during high-traffic events. A user in Germany trying to sign up for a US service might never receive the code because the intermediate carrier flagged the bulk SMS sender as spam.

Beyond the technical failures, the user experience of SMS OTPs is inherently high-friction on mobile devices. It forces the user to leave the context of the application (the checkout flow) to open the Messages app, memorize the code (or copy it) and switch back. This context switching breaks the cognitive flow. On older devices or aggressive memory-management operating systems, switching apps can cause the browser page to reload, resetting the checkout process entirely and clearing the form data.

While "Auto-fill OTP" features on iOS and Android have mitigated this slightly, they are not universally supported and often fail if the SMS format doesn't match the OS heuristic. The reliance on SMS OTPs is a "patch" that has become a barrier, driving up operational costs (SMS fees are rising) and driving down conversion rates.

How to detect it: Segment your login success rate by method. If "Sign in with Google" dropped 10-20% recently without any code changes on your end, browser-level changes (FedCM migration) are likely the cause.

Why it matters: Social login was supposed to be "set and forget." It's not anymore. Chrome's Privacy Sandbox and the FedCM API migration is progressively affecting legacy implementations. Unlike password failures (which users blame on themselves), social login failures get blamed on your site - eroding trust instantly.

                    : Automatic sign-in friction increases

The browser ecosystem, led by Google Chrome's Privacy Sandbox initiative, is phasing out third-party cookies to enhance user privacy and prevent cross-site tracking. Traditional federated login implementations (like the legacy Google Sign-In library) relied heavily on these cookies and hidden iframes to check if a user was logged into Google while visiting a third-party site. With third-party cookies being blocked, these legacy flows are breaking.

To replace the functionality of third-party cookies for authentication, browsers are introducing FedCM (Federated Credential Management API). This is a browser-native API that handles identity federation in a privacy-preserving way, allowing the browser to mediate the login without exposing the user's entire browsing history to the Identity Provider (IdP). While this is a positive step for privacy, the migration represents a massive disruption for conversion optimization.

Google is recommending migration to FedCM for its Identity Services (GIS). The rollout has been staged: FedCM entered beta in August 2023 and Google has progressively expanded its adoption while providing compatibility paths for legacy implementations. During this transition, users may experience new, unfamiliar browser prompts. Instead of the familiar, customized "Sign in with Google" pop-up or iframe that sites have designed to match their branding, users might see a generic, browser-controlled modal (the "FedCM dialog") that looks different, behaves differently and creates hesitation.

Crucially, implementing FedCM often requires code changes on the Relying Party (the website). If a site has not updated its implementation or if it uses custom iframes that conflict with the new permissions policies or Content Security Policies (CSP), the social login button may simply fail to load or throw errors upon clicking. For a user, this looks like a broken site. They click "Sign in with Google," nothing happens or they get a generic "Something went wrong" error or a 500 status.

Unlike a password failure, which the user blames on themselves, a social login failure is blamed on the site. The trust is broken immediately. The user assumes the site is buggy or insecure and abandons the session.

Furthermore, the "automatic sign-in" flows - where a user is logged in without clicking anything if they have an active Google session - are being throttled or gated by user gestures under the new regime to prevent tracking. This means users who used to glide into the product automatically are now being stopped and asked to explicitly confirm their identity via a prompt. This re-introduction of friction in a previously frictionless flow can depress conversion rates for returning users.

This breakage is particularly insidious because it is often intermittent. It depends on the specific Chrome version the user is running, the rollout percentage of the FedCM API (which Google adjusts) and the user's specific privacy settings. A sudden drop in social login conversion rates might be due to a browser update pushing FedCM to 100% of traffic, leaving product teams baffled as they search for bugs in their own code that don't exist. The "Sign in with Google" button, once a set-it-and-forget-it feature, now requires active maintenance and monitoring to ensure it doesn't become a dead end.

How to detect it: Compare conversion rates by device type. If mobile traffic is 70%+ but mobile conversion lags desktop by 30% or more, cross-device handover friction is a likely culprit. Also check: session timeout rates at checkout.

Why it matters: Users browse on mobile, buy on desktop. If authentication state doesn't transfer seamlessly, you're forcing re-login at the worst possible moment. And aggressive session timeouts (often set by security/compliance) kill conversions mid-checkout.

The "cross-device gap" is a well-documented phenomenon in e-commerce. Mobile traffic accounts for approximately 75% of visits, yet mobile conversion rates (approx 2%) lag significantly behind desktop conversion rates (approx 3%). While screen size plays a role, a significant contributor to this gap is the inability to seamlessly transfer authentication state.

Consider a common scenario: A user on a smartphone clicks an ad, browses a store and adds items to a cart. They are "guest" browsing. They decide to finish the purchase on their laptop where it's easier to type credit card details. When they open the site on the desktop, their cart is empty. To retrieve it, they must log in. However, if they create an account on mobile, they might have used a "Suggest Password" feature (like Apple's Keychain) that created a complex string they never saw. Now, on their Windows desktop, they don't know the password.

They are effectively locked out of their own intent. They must initiate a password reset on the desktop, which sends an email to their phone, forcing a cumbersome loop of device switching that often results in abandonment. The friction of bridging the air gap between mobile and desktop is too high.

Session timeouts often get set by security/compliance teams (PCI-DSS, etc.) without input from product. A 15-minute timeout sounds reasonable until you realize "inactivity" to a server is "looking for a coupon code" or "checking a competitor's price" to a user.

User opens checkout → tabs away for 20 minutes → returns → clicks "Pay" → "Session Expired." This is the digital door slam—and it happens at the bottom of your funnel, after the user already committed.

This friction is particularly damaging because it happens at the absolute bottom of the funnel. The user has already done the work; they have committed to the conversion. The system's rejection feels punitive. Unlike abandonment at the entry, abandonment at the checkout due to timeout is a rejection of a completed sale. If the application does not auto-save the form data (shipping address, un-tokenized payment info), the user must re-enter everything. The frustration is compounded by the lack of warning. Best practices suggest warning users before a timeout ("You will be logged out in 60 seconds"), but many implementations simply kill the session silently. For 60% of consumers, login frustration - including these timeouts - is a cited reason for abandoning an account or service entirely. The rigorous application of security policies regarding session length often ignores the human reality of attention spans, resulting in a secure but empty application.

How to detect it: Check if MFA step-up rates spiked after a security incident. Look for sudden increases in "suspicious activity" blocks that correlate with conversion drops. Survey customer support for "I can't log in" ticket volume.

Why it matters: Security and product teams often operate in silos. After a credential stuffing attack or compliance audit, security adds friction (mandatory MFA, aggressive risk scoring) without visibility into conversion impact. The result: fraud drops, but so does revenue. The goal isn't to weaken security—it's to find methods (like passkeys) that are both more secure AND less friction.

A common scenario: Your platform experiences a credential stuffing attack. Security responds by enabling mandatory MFA or tightening risk-based authentication thresholds. The attack stops but so does a chunk of legitimate traffic. Neither team has visibility into the other's metrics, so the trade-off goes unquantified.

Overnight, users who previously logged in smoothly now hit mandatory MFA setup screens or get flagged as "suspicious" for logging in from a new location. Step-up authentication kicks in more aggressively.

The fraud stops but so does a portion of legitimate traffic. Risk-based authentication (RBA) systems have false positive rates that directly impact conversion. Ironically, high-value purchase attempts (exactly what you want) are most likely to trigger "anomalous behavior" flags if thresholds are too sensitive.

The fix isn't to weaken Security. It's to adopt auth methods that are inherently more secure AND less friction: passkeys being the prime example. Phishing-resistant by design, no step-up needed.

Common reactive measures add friction without addressing root cause:

• CAPTCHAs (user hostile, increasingly bypassed by bots)
• Knowledge-based authentication ("What was your first car?")—easily social-engineered
• SMS codes—delivery issues plus cost scaling

"Adaptive MFA" tries to thread the needle by only challenging risky logins. But when implemented reactively (post-incident, without baseline data), thresholds are often too aggressive and users don't understand why they're sometimes challenged and sometimes not.

Better approach: Establish authentication analytics before an incident, so you have baseline data. When security tightening is needed, you can measure impact and tune thresholds with real conversion data—not guesswork.

When a user reports "I can't log in," how long does it take your team to diagnose the root cause? Hours? Days? If you don't have authentication-specific instrumentation, you're flying blind and your engineers will spend cycles on issues they can't reproduce.

This section provides the framework to turn vague support tickets into actionable data.

The typical debugging process for authentication issues involves:

1. Check backend logs for the user's email/session
2. Look for authentication-related errors
3. Pull a session replay (if tools like Hotjar, Microsoft Clarity or Quantum Metric are available)
4. Manually correlate frontend behavior with backend events

This process can take hours or days. Meanwhile, the team has no visibility into whether the issue affects one user or thousands.

Step 1: Classify the failure type

Step 2: Segment the Data

Avoid looking at global failure rates. A 90% login success rate might mask a 50% failure rate for mobile users. Slice by:

• Device/browser: Chrome on Android failing while Safari on iOS succeeds indicates a specific bug.
• Auth method: If password has 90% success but social login has 60%, focus on the social login implementation.
• Entry touchpoint: If header login has 95% success but checkout login has 70%, the checkout flow has unique friction.
• New vs. returning: New users failing suggests registration issues; returning users failing suggests password/session problems.
• Region/market: Social login preferences vary dramatically (Facebook strong in US, Kakao/Naver in Korea, Google dominant in Europe). SMS delivery reliability also varies by carrier and country.

Step 3: Reproduce the exact Scenario

Once a pattern is identified, reproduce it using:

1. Same device type
2. Same browser version
3. Same auth method
4. Same entry point

Session replay tools can reveal issues that logs cannot capture—UI elements not rendering, buttons not responding, or error messages appearing and disappearing too quickly.

You do not need to rebuild your stack to measure friction. Implement these events in your existing analytics tool (Mixpanel, Amplitude, Google Analytics):

Good news: you don't need to rip out your identity provider (Auth0, Cognito, ForgeRock, Ping, etc.) to see improvement. Many high-impact fixes are UX-layer changes that ship in a single sprint and give you data to justify larger investments.

Before implementing new technology, fix the interface:

• Unmask Password: Add a "Show Password" (eye icon) button by default. This simple change reduces typo-based failures on mobile devices significantly, cutting down on "Incorrect Password" errors and unnecessary resets.
• Persistent Login Options: If a user previously logged in with Google, highlight the Google button the next time they return. Do not make them remember how they signed up. Use a "You last used Google" badge. This reduces cognitive load and prevents duplicate account creation.
• Inline Validation: Do not wait for the "Submit" click to tell the user their password is too short. Validate inline, in real-time. This feedback loop prevents the frustration of page reloads.
• Stay Logged In: Extend session durations for non-sensitive actions. If a user is just browsing products, do not time them out. Only challenge them (re-auth) when they attempt to change account settings or complete a purchase.
• Auto-Focus: When the login modal opens, the cursor should be in the email field automatically. On mobile, the correct keyboard (email layout) should trigger. These micro-interactions shave seconds off the "Time to Value."

UX tweaks help, but the biggest lever is removing the friction source entirely: the password.

Passkeys solve Symptoms 1, 2, 3, and 6 in one change:

• No typing: Users authenticate with Face ID/Touch ID/Windows Hello - no password to misremember.
• No delivery delays: No SMS code to wait for. The credential lives on the device.
• No resets: You can't forget a passkey. It syncs via iCloud Keychain or Google Password Manager.
• Better security: Passkeys are phishing-resistant by design, so security teams get stronger auth without adding friction.

Rollout strategy for risk-averse teams:

Most organizations don't need to force passkeys on day one. A phased approach de-risks the launch:

1. Phase 1 - Opt-in append: After a successful password login, prompt: "Want to sign in faster next time?" Create passkey with one tap. This builds passkey coverage without changing the default flow.

2. Phase 2 - Conditional UI: Enable passkey autofill in the username field. Users with passkeys get zero-click login; others see the normal flow.

3. Phase 3 - Opt-out for new accounts: New registrations default to passkey creation. Password becomes the fallback, not the default.

This lets you measure adoption and success rates at each phase before expanding—exactly the data you need for stakeholder buy-in.

You probably have sophisticated checkout analytics. But can you answer these questions about authentication?

• Which device/browser combinations have the highest login drop-off?
• What percentage of passkey logins fail implicitly (technical issue) vs. explicitly (user cancelled)?
• When a user reports "I can't log in," can you diagnose root cause in minutes—not days?
• How does login success rate differ between header login vs. checkout login?

If not, you have the same blind spot most teams have. Corbado provides authentication-specific observability—purpose-built for teams running their own WebAuthn/passkey implementation who need Corbado-level analytics without changing their auth backend.

Corbado's telemetry captures every step of the authentication journey with granular visibility:

• Funnel Analytics: Track conversion rates at each authentication step - from "login initiated" to "passkey prompt shown" to "biometric completed" to "session established." Identify exactly where users abandon.
• Device-Level Insights: Understand which device/browser combinations have the highest drop-off. If Android Chrome users fail at 3x the rate of iOS Safari, you'll know immediately.
• Error Attribution: When authentication fails, Corbado captures the specific failure reason (user cancelled, biometric timeout, credential not found, network error). This transforms vague "login issues" tickets into actionable data.

Beyond visibility, Corbado enables continuous optimization:

• A/B Testing: Test different nudge placements, copy variations and timing strategies for passkey enrollment. Does prompting post-checkout convert better than post-login?
• Cohort Analysis: Segment users by passkey adoption status and track downstream metrics. Do passkey users have higher repeat purchase rates? Lower cart abandonment?
• Real-Time Dashboards: Monitor authentication health during high-traffic events (Black Friday, product drops). See login success rates and passkey adoption in real-time.

The analytics layer feeds directly into remediation. Once you identify that checkout login has 20% lower success than header login, or that mobile password resets have 40% abandonment, Corbado's passkey infrastructure provides the fix:

• Passkey Overlay: Add passkeys on top of your existing password infrastructure without a total rewrite. When a user successfully logs in with a password, prompt: "Want to sign in faster next time?"
• Conditional UI: Use the browser's autocomplete to offer passkeys in the username field, enabling zero-click recognition for returning users.
• SMS Cost Elimination: Every passkey login is one less SMS billable event. Customers typically see 70%+ reduction in SMS-based authentication costs.

For organizations where a 1% conversion lift equals six figures in annual revenue, the ROI of authentication observability is immediate and measurable. Learn more about Corbado's analytics capabilities.

Login friction isn't a technical nuisance. It's a revenue problem hiding in a metrics blind spot.

The six symptoms covered here are identifiable and fixable:

1. Checkout login walls: Add friction-aware alternatives (guest checkout, social login prominence)
2. Password fatigue: Track reset rates, implement passkey append flows
3. SMS delivery failures: Measure OTP success rates by region/carrier, consider alternatives
4. Social login breakage: Audit FedCM compliance as Chrome continues deprecating third-party cookies
5. Cross-device gaps: Extend sessions for low-risk actions, improve mobile login UX
6. Reactive security friction: Align security and product on shared metrics

The meta-problem: Most organizations can't see authentication friction in their analytics. Bounces get logged; root causes don't.

The path forward:

1. Instrument the auth funnel (events in Section 8.3 are a starting point)
2. Segment by device, method, and touchpoint to find where friction concentrates
3. Fix the highest-impact issues first (often UX changes that ship in one sprint)
4. Build the business case for passkeys with real data from phases 1-2 of rollout

Authentication is the one step every user must complete. Optimizing it isn't optional—it's the highest-leverage conversion work most teams aren't doing.
