Guest checkout lets users complete a purchase without creating an account: just email, shipping address and payment. Forced login requires account creation before purchase. This choice directly impacts conversion rates, customer data quality and long-term loyalty. With cart abandonment averaging above 70% and authentication friction responsible for much of that drop-off, choosing correctly determines funnel profitability.

The tension usually is that logged-in users are more valuable but guest checkout has higher first-purchase conversion. Industry data shows registered customers convert at 64% vs 52% for guests. This disparity stems from three factors:

• Frictionless Repeat Purchasing: A logged-in user has saved shipping addresses and payment methods. Their subsequent checkout speed is measured in seconds, not minutes.
• Personalization and AOV: Identity enables recommendation engines to use past purchase history for targeted cross-sells that increase Average Order Value.
• Retention and Reachability: Registered users can be targeted with abandoned cart emails (which have ~40-50% open rates and can recover 5-10% of abandoned carts), loyalty rewards and re-engagement campaigns.

Forcing registration risks alienating customers - ~24% abandon because they were asked to create an account - while checkout without login leaves merchants blind to behavior.

Guest checkout prioritizes velocity: secure the transaction now and capture the customer's identity later. The merchant asks only for order fulfillment data (email, shipping address, payment) without an actual account / password creation.

There are the following benefits of allowing checkout without account:

• No password creation: This removes the "memory tax" for first-time buyers
• Speed: In under 3 minutes with autofill and under 30 seconds with digital wallets (Apple Pay, Google Pay) you can complete the checkout
• Privacy perception: Users feel less tracked when checking out as guest

The downside of guest checkout is structural data blindness:

• No Behavioral Linking: The merchant cannot connect this purchase to previous behavior unless they rely on fragile browser cookies or device fingerprinting.
• Support Costs: Guest users cannot easily track orders via self-service portals. They must contact customer support for status updates, increasing operational overhead.
• Lower Repurchase Rate: Because payment details are not saved, the user must re-enter all data upon their next visit. The industry average repeat purchase rate for guest users hovers at the lower end of the 20-30% range.
• "Ghost User" Problem: If a user buys as a guest three times using the same email, the backend often treats them as three distinct transactions. This fragmentation makes it difficult to calculate true LTV or segment high-value customers.

The forced login model prioritizes data integrity and LTV. It bets that the product's value proposition, scarcity or price point is sufficiently high to overcome the natural friction of account creation.

Some retailers require registration because e.g. furniture is high-consideration and multi-session. Users browse, compare, measure, add to cart, leave and return days later. The login wall ensures cart persistence across devices and sessions.

Benefits of forced login:

• Cart Persistence: The cart becomes a project board that survives device switches and session timeouts.
• Unified Customer Profile: All transactions, preferences and interactions are linked to a single identity.

Despite benefits, forcing login carries substantial risks:

• High Bounce Rate: Authentication friction is a major abandonment driver. Baymard Institute research shows ~24% of users cite "site wanted me to create an account" as their reason for abandoning checkout.
• Password Fatigue: Approximately 19% of users abandon carts specifically because they have forgotten their password. Overly complex password requirements cause another 18-20% of drop-offs according to Baymard's checkout UX research.
• Database Pollution: Users forced to register often input throwaway emails or simple, insecure passwords just to bypass the gate.
• Brand Resentment: Forced registration signals that the brand values its own data collection mandates over the user's convenience, damaging NPS and long-term brand affinity.

Most analytics stacks track only the Success/Fail of an authentication but miss the details. See our authentication analytics playbook for comprehensive measurement of authentication analytics.

Guest vs. Member Conversion Rate: At first, you need to track the conversion rate of guests vs logged-in users.

Login Drop-off Delta: Moreover, you should measure the delta between the two events login_modal_opened and login_successful.

By looking at these key metrics, you already get a first understanding of the impact of guest vs. member checkouts.

Aggregated data from extensive longitudinal studies indicates that the average shopping cart abandonment rate has stabilized just above the 70% mark:

This means that if your cart abandonment rate is higher, you should investigate the issues.

Mobile abandonment reaches ~85% (a 15-point delta from desktop). Typing email/password on a virtual keyboard in distracting environments creates severe friction.

Besides segmentation by device, it's helpful to segment by channel as well.

By channel:

• SEM: customers coming from paid ads tend to have higher intent and lower patience (for them login walls hit hardest)
• Direct: direct traffic are often returning customers for whom login walls are less damaging
• Social: traffic from your socials is often impulse-driven and mobile-first (having a guest checkout is a great choice here)

The following chart shows a typical checkout process and corresponding checkout conversion rates.

Sophisticated merchants bridge "Guest" and "Forced Logins" with hybrid patterns. Thus, they can maintain velocity while encouraging identity creation.

The "Continue as Guest" button placement dramatically affects behavior:

• Prominence: The "Guest Checkout" option must be equally prominent to the login option. Hiding it in a text link below the fold causes frustration. 62% of sites fail to make this option sufficiently prominent according to Baymard's checkout UX benchmarks.
• Copy Matters: "Continue as Guest" outperforms "Checkout without Account" because it implies progression rather than exclusion.
• Visual Hierarchy: Equal button sizing signals that guest checkout is a valid, first-class option, not a fallback.

Guest checkout example: Sephora employs "soft barriers" displaying "Sign in to use your 500 points" or "Members get free shipping" without blocking the guest path (case study).

The "Email-First" pattern eliminates binary "Login vs. Register" Users see one field: "Enter your email to continue."

• If the email is new: The user is guided to a flow that looks like a guest checkout. The password creation is often deferred to the final step or handled via a magic link.
• If the email is known: The user is prompted for a password but provided a link to continue as guest if they fail.

This pattern, used by brands like Wayfair, Amazon and Nike, separates the identification step (who are you?) from the authentication step (prove it).

Post-purchase account creation prioritizes the sale, then converts guests on the "Thank You" page.

• Mechanism: Since the user has already entered their name, email and address, the "account creation" step is reduced to a single action: setting a password. The friction is minimal because most of the data entry is already complete.
• Psychology: The user has already committed to the purchase (Endowment Effect). Creating an account now feels like "saving progress" rather than "doing work."
• High-Converting Copy: Instead of "Create an Account," use benefit-driven copy like "Track your order," "Save your details for next time," or "Get 10% off your next order" as detailed in thank you page conversion strategies.

Calculating LTV for guests requires Identity Resolution tools matching transactions via email, phone or address hash.

Key cohorts to build:

• Guest-to-Account Conversion Rate: What percentage of guest purchasers convert to registered accounts (via post-purchase flow or subsequent visit)?
• Ghost User Rate: What percentage of "Guest" transactions are actually returning customers who simply didn't log in?
• LTV by Acquisition Path: Compare lifetime value of users who registered at first purchase vs those who converted later.

If the Ghost User rate is high, your login flow is failing to capture existing value - a clear signal to improve returning customer detection.

Passkeys render the guest vs forced login discussion to a certain degree obsolete. They basically llow to achieve a "Forced Login" with "Guest Checkout" speed.

Passkeys let users authenticate with biometrics (e.g. Face ID, Touch ID), so never requiring a password.

Enrollment pattern: After password login or guest checkout, prompt: "Create a passkey for faster checkout next time?" One Face ID scan is all to create the passkey.

Now for subsequent logins you can make use of the same seamless UX or use Conditional UI (passkey autofill) for an even usernameless login.

Early adopters of passkeys in e-commerce report staggering improvements:

• Login Time: Reduced by 50% to 73% compared to password/MFA flows.
• Success Rates: Login success rates improve by over 10% due to the elimination of typos and forgotten credentials as shown by outcome-based SCA research.
• Business Case: The ROI includes higher conversion, reduced SMS costs (no OTPs) and reduced support tickets according to a passkey adoption business case.

Broader industry trends reinforce this direction:

Network-Centric Identity: Visa and Mastercard are pushing "Click to Pay" where the card network acts as the identity provider. The merchant gets registered user data with guest-user speed as detailed in the payment passkey landscape overview.

The strategies in this article only work if you can see what's happening. Most analytics tools treat authentication as a black box. You know users bounced, but not why. Corbado provides authentication-specific observability purpose-built for checkout flows.

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

• Funnel Analytics: Track conversion at each checkout auth step: from "sign-in clicked" to "passkey prompt shown" to "biometric completed" to "session established." See exactly where users abandon.
• Device-Level Insights: Understand which device/browser combinations have the highest drop-off. If mobile Safari users fail at 3x the rate of desktop Chrome, you'll know immediately.
• Error Attribution: When authentication fails, Corbado captures the specific failure reason (e.g. user_cancelled, biometric_timeout, credential_not_found, network_error). This transforms vague "login issues" into actionable data.

Corbado allows you to monitor your authentication's health during main events like Black Friday, product drops or flash sales:

• See login success rates and passkey adoption in real-time
• Get alerts when checkout authentication drop-off exceeds thresholds
• A/B test different "Continue as Guest" vs "Sign in" placements / policies with live conversion data

For organizations where a 1% conversion lift equals six figures in annual revenue, the ROI of authentication observability is immediate and measurable.

The core tension remains: registered customers convert at 64% vs 52% for guests, yet ~24% abandon when forced to create an account. The solution isn't choosing one or the other.

Key takeaways:

• Hybrid patterns win: Use Email-First detection for returning customers, prominent "Continue as Guest" buttons and post-purchase account creation to capture identity without blocking the sale.
• Measure what matters: Track guest vs member conversion rates, the login drop-off delta and segment by device/channel. Mobile abandonment at ~85% demands special attention.
• Passkeys change the equation: With biometric authentication, account creation becomes as fast as guest checkout. One Face ID scan replaces password friction entirely.
• Invest in observability: If you can't see where users drop off in your auth flow, you can't fix it. Authentication-specific analytics (like Corbado) turn "login issues" into actionable data.

The winning e-commerce strategy uses passkeys and hybrid patterns to achieve both velocity and data collection simultaneously.
