Introduction: Cognito vs. Corbado Passkeys Passkeys are quickly becoming the new standard for secure, [passwordless authentication](https://www.corbado.com/glossary/passwordless-authentication) offering better UX, stronger security and lower costs compared to SMS or [authenticator](https://www.corbado.com/glossary/authenticator)-based MFA. With [big tech](https://www.corbado.com/blog/big-tech-vs-passkey-aggregators) (Apple, Google and Microsoft) backing the technology, [passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case) is accelerating across industries. > See also what [AWS](https://www.corbado.com/blog/passkeys-amazon-cognito) says it its blog on > [optimizing passkey adoption with Amazon Cognito and Corbado](https://aws.amazon.com/blogs/apn/maximizing-passkey-adoption-with-amazon-cognito-and-corbado/) But implementing passkeys is one thing. Driving actual user adoption - especially in [large-scale](https://www.corbado.com/blog/introducing-passkeys-large-scale-overview), enterprise environments - is another. [Watch on YouTube](https://www.youtube.com/watch?v=YOB0h4ggKGs) That’s where solutions like [Amazon Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) and Corbado come in. While both offer passkey capabilities, they’re built for different use cases. In this post, we’ll break down the following questions: 1. What are the key differences between [Corbado Passkeys](https://www.corbado.com/blog/passkey-performance-testing) vs [Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) Passkeys? 2. When should you use [Corbado Passkeys](https://www.corbado.com/blog/passkey-performance-testing) and when rather use [Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) Passkeys? 3. How can you increase the passkey user adoption if your IdP is [Amazon Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito)? Moreover, we’ll outline how Corbado’s Enterprise Passkey Platform works on top of [AWS](https://www.corbado.com/blog/passkeys-amazon-cognito) [Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito). ## 2. Why Passkeys matter for modern Applications Passwords are the weakest link in most authentication flows: they’re reused, phished and forgotten. Even traditional MFA (like SMS or [authenticator](https://www.corbado.com/glossary/authenticator) apps) introduces friction and cost, especially at scale when you’re dealing with millions of users). Passkeys, based on the WebAuthn and [FIDO2](https://www.corbado.com/glossary/fido2) standards, solve these issues: - **Phishing-resistant**: Passkeys can’t be entered on fake websites. - **Faster logins**: No codes, no [password reset](https://www.corbado.com/blog/password-reset-increase-customer-retention) flows – just use Face ID or Touch ID. - **Lower support costs**: Fewer [password resets](https://www.corbado.com/faq/passkeys-reduce-password-resets-otp-costs), fewer login issues. - **Better user experience**: if implemented right, passkeys increase [conversion rates](https://www.corbado.com/blog/logins-impact-checkout-conversion) and retention. But passkeys aren’t just a plug-and-play feature, especially for large user bases. They require thoughtful integration and UX design to truly drive adoption and deliver value. ## 3. Passwordless Authentication in AWS: Overview of Cognito Passkeys [Amazon Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) introduced [support for passkeys (WebAuthn / FIDO2) in November 2024](https://aws.amazon.com/about-aws/whats-new/2024/11/amazon-cognito-passwordless-authentication-low-friction-secure-logins), allowing developers to add passwordless login via biometric [authenticators](https://www.corbado.com/glossary/authenticator) such as [Face ID](https://www.corbado.com/faq/is-face-id-passkey), [Windows Hello](https://www.corbado.com/glossary/windows-hello) or [hardware security keys](https://www.corbado.com/blog/best-fido2-hardware-security-keys) (e.g. [YubiKeys](https://www.corbado.com/glossary/yubikey)). ![amazon cognito passkey signin](https://www.corbado.com/website-assets/amazon_cognito_passkey_signin_54fd01a07d.png) ### 3.1 How AWS Cognito implements Passkeys ![aws cognito passkey overview](https://www.corbado.com/website-assets/aws_cognito_passkey_overview_aeed9fd9c4.png) [AWS Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) handles basic passkey registration and authentication. It’s optimized for usage via Cognito’s **Hosted UI / Managed Login**. If you don’t use the Hosted UI / Managed Login, there’s significant effort you need to put get passkeys to work via Cognito as your identity provider. ![aws cognito passkey edit](https://www.corbado.com/website-assets/aws_cognito_passkey_edit_db3fe4fdf1.png) The WebAuthn ceremonies are managed by Cognito internally. Cognito has the following characteristics in regard to WebAuthn server modification: - The [PublicKeyCredentialCreationOptions](https://www.corbado.com/glossary/publickeycredentialcreationoptions) and [PublicKeyCredentialRequestOptions](https://www.corbado.com/glossary/publickeycredentialrequestoptions) are abstracted away - developers can't customize them. - Passkeys are linked to a user’s Cognito sub (unique [User ID](https://www.corbado.com/blog/webauthn-user-id-userhandle)). - FIDO metadata is stored and managed inside the Cognito user pool - developers don’t interact with raw credentials. ![aws cognito signin passkey](https://www.corbado.com/website-assets/aws_cognito_signin_passkey_ca83542c37.png) Amazon Cognito [PublicKeyCredentialCreationOptions](https://www.corbado.com/glossary/publickeycredentialcreationoptions): ```json { "attestation": "none", "authenticatorSelection": { "residentKey": "required", "userVerification": "required" }, "challenge": "_nv4xozlsmeyXlbpDL2rhA", "excludeCredentials": [], "pubKeyCredParams": [ { "alg": -7, "type": "public-key" }, { "alg": -257, "type": "public-key" } ], "rp": { "id": "eu-central-1stube6mkt.auth.eu-central-1.amazoncognito.com", "name": "eu-central-1stube6mkt.auth.eu-central-1.amazoncognito.com" }, "user": { "displayName": "vincent.delitz@corbado.com", "id": "NzM5NGI4YTItMjAwMS03MDdlLTRjNzgtZDZjMzliNjY4NjFl", "name": "vincent.delitz@corbado.com" } } ``` The [Relying Party](https://www.corbado.com/glossary/relying-party) ID here is ` eu-central-1stube6mkt.auth.eu-central-1.amazoncognito.com` but can modified in the Cognito settings. As WebAuthn `user.id` Cognito does not use the internal Cognito [User ID](https://www.corbado.com/blog/webauthn-user-id-userhandle) but instead another unique value. Amazon Cognito [PublicKeyCredentialRequestOptions](https://www.corbado.com/glossary/publickeycredentialrequestoptions): ```json { "allowCredentials": [ { "id": "KckRxRA_1S7IscxX1qiseHygvKU", "transports": ["hybrid", "internal"], "type": "public-key" }, { "id": "W50i_-WwK8zlovW7r81Pg09FudY", "transports": ["internal"], "type": "public-key" } ], "challenge": "4II_qZp281jnGVDmwloEPg", "rpId": "eu-central-1stube6mkt.auth.eu-central-1.amazoncognito.com", "userVerification": "required" } ``` Here, you can see that Cognito makes active use of the [allowCredentials](https://www.corbado.com/glossary/allowcredentials) array to list all the existing passkeys of a user. #### 3.1.1 User Experience of Cognito Passkeys From a user perspective, [AWS Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito) only offers the separate [passkey button approach](https://www.corbado.com/faq/passkey-button-approach). This means the user has to deliberately click on the “Continue” button that triggers the [passkey login](https://www.corbado.com/blog/passkey-login-best-practices) to start. This good for [account enumeration](https://www.corbado.com/faq/account-enumeration-risk-passkeys) protection, however, has a bad user experience as users will keep on using their password as they don’t change existing behavior easily. In contrast, better UX and higher [passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case) can be achieved with an automatic start of the passkey authentication process after providing the identifier. This would result also in a higher login rate for passkeys. #### 3.1.2 Passkeys without Hosted UI / Managed Login If you're not using Cognito’s Hosted UI or Managed Login, implementing passkeys becomes significantly more complex. You need to manually handle WebAuthn ceremonies, securely manage credentials, and ensure fallback logic for unsupported devices. This is especially painful in **custom frontend applications**, where Cognito’s SDKs don’t offer out-of-the-box passkey orchestration. ### 3.2 Developer Constraints Amazon Cognito passkeys are very limited in their supported passkeys / WebAuthn features. At this stage, Cognito offers only to [create a passkey](https://www.corbado.com/blog/passkey-creation-best-practices) and use one to log in. The following things are currently a constraint. - **Limited Visibility & Analytics**: No analytics on registration success, drop-off rates or which devices/browsers support WebAuthn. - **No Conditional UI**: In the Hosted UI / Managed Login, the browser's [passkey autofill](https://www.corbado.com/blog/webauthn-conditional-ui-passkeys-autofill) (i.e. mediation: "conditional") is not supported, which means no [passkey login](https://www.corbado.com/blog/passkey-login-best-practices) prompt without a user click. - **No Customization**: You can’t really change the passkey UI and messaging. Also, the error handling doesn’t provide real insights for users. - **No Passkey Intelligence**: It’s a very simple passkey implementation that doesn’t have any intelligence that one would require to log in hundreds of thousands of users with different devices. It’s clear that [passkey adoption](https://www.corbado.com/blog/passkey-adoption-business-case) was not a target when developing the Cognito passkey offering. If you're using Cognito for **custom frontend passkey login**, be prepared for limited flexibility - especially when it comes to fallback handling, registration UX, and analytics. ### 3.3 Use Cases where Cognito Passkeys fit Cognito’s passkey support is a good choice if: - You're building a **new app** and plan to use other authentication methods from Cognito as well. - You don't need **custom UX, branding** or **progressive enhancement**. - You want to get started quickly and are okay with a **manual “Sign in with passkey”** button. - You don’t need a high passkey adoption. ### 3.4 Where Cognito Passkeys fall short Cognito doesn’t address **passkey adoption**. Users need to manually register and opt in. There’s no fallback intelligence, no A/B testing and no insight into what works and what doesn't. Let’s assume for a regular web application the following device share based on observed traffic: | **Operating System** | **Share** | | -------------------- | --------- | | Windows 11 | 15% | | Windows 10 | 10% | | macOS | 12% | | iOS | 44% | | Android | 19% | When predicting the passkey adoption with our internal tools, the outcome after 36 months predicts a [passkey login rate](https://www.corbado.com/kpi/passkey-usage-rate) of 1.4% (no [Conditional UI](https://www.corbado.com/glossary/conditional-ui)): ![aws cognito passkey adoption simulation](https://www.corbado.com/website-assets/aws_cognito_passkey_adoption_simulation_368097b8fd.png) If you're managing: - Large existing user bases - Custom frontends ([React](https://www.corbado.com/blog/react-passkeys), [Angular](https://www.corbado.com/blog/angular-passkeys), etc.) - Complex login flows (fallbacks, conditional logic) - High adoption or ROI targets …Cognito alone likely won’t be enough. ## 4. Introducing Corbado’s Passkey Solution While Cognito offers basic passkey functionality, **Corbado** focuses on optimizing **passkey adoption, UX and large-scale deployment**, especially in environments where custom frontends and millions of existing users are involved. Corbado is not an Identity Provider (IdP). Instead, it sits **on top of your existing authentication system** - like Amazon Cognito, [Keycloak](https://www.corbado.com/blog/keycloak-passkeys), Azure AD B2C, Duende IdentityServer or even a custom backend - and provides a **passkey orchestration layer** designed to drive real-world passkey adoption. ### 4.1 What Corbado does Corbado handles the full passkey lifecycle - registration, authentication, passkey discovery, fallback logic and [passkey intelligence](https://docs.corbado.com/corbado-connect/features/passkey-intelligence) - while integrating into a custom frontend via frontend UI components. The backend is connected via SDKs and secure backend-to-backend calls. Corbado includes the following main features: - **Enterprise Gateway (Enterprise WebAuthn Server):** Corbado's enterprise-grade WebAuthn server is optimized for high availability and passkey management while providing connectors to your IdP / CIAM. - **Components & SDKs (Ready-Made UI Kits & Passkey UX):** Leverage our ready-to-use frontend components and SDKs to quickly integrate passkey authentication in your CI without reinventing the wheel. - **Analytics & Tracking (Passkey Adoption & Activation Data):** Corbado monitors key metrics that determine your passkey deployment's success - incl. adoption, activation & login rates - to help you optimize performance. - **Login Observability (Analyze & Optimize Login Paths):** Understand how users log in and where bottlenecks occur. Corbado collects hundreds of signals per login to help you analyze and optimize the user journey. - **Adoption Accelerator (Get 10x Higher Passkey Adoption):** True passkey adoption requires users to create and use their passkeys. Corbado is built to maximize both [passkey creation](https://www.corbado.com/blog/passkey-creation-best-practices) and usage. - **Gradual Rollout (Roll out Passkeys the Riskless Way):** Corbado enables staged rollouts (e.g. by device type or user cohort), A/B testing, and risk-free deployment - ideal for large user bases. ### 4.2 What makes Corbado different? Cognito implements passkeys. Corbado **optimizes** them. > “Passkey implementation ≠ passkey adoption.” This is one of our key learnings from real-world passkey deployments. Corbado actively drives adoption through: - **One-tap login flows**: Automatically invoke [passkey login](https://www.corbado.com/blog/passkey-login-best-practices) after email input using stored metadata. - **Inline passkey registration**: Seamless prompts after login or during onboarding - no detour to account settings. - **Smart fallback logic**: If a device doesn’t support passkeys or none is registered, Corbado automatically reverts to password/SMS with clear guidance. - **Analytics & recovery insights**: View passkey usage, drop-off points, error reasons, and recovery flows. - **Passkey Intelligence: Leverage millions of collected data points and signals across device, OS, browser, user, passkey and meta data to determine if a passkey can pushed.** ### 4.3 Ideal Use Cases for Corbado Corbado is a fit if you: - Have a **custom frontend** and don’t use Cognito’s Hosted UI / Managed Login. - Manage **millions of users** and want to avoid user migration but still want to offer passkeys to them in an enterprise-friendly way. - Need **enterprise-grade** control over UX, fallback behavior and analytics. - Want to **reduce MFA costs** (e.g. SMS OTP) while improving login speed and security. Using the same passkey adoption tool and operating system share as above, for the same device and application data, we can predict a [passkey login rate](https://www.corbado.com/kpi/passkey-usage-rate) of 47.5% after 36 months: [![corbado passkey adoption simulation](https://www.corbado.com/website-assets/corbado_passkey_adoption_simulation_7b96b24205.png)](https://resplendent-mochi-9f57cb.netlify.app/eJxlkE1LxDAQhv9K6dVJnEk62eYoC4IH2YOCh5JDtVUDSyJtYfHfO10_aNaZ28Mz8L7TdV39FNOQT3NFVAMxtAyWA2w4CkfgX37fvxweBBnwK11RXEHTgGfYncFNGqYcB7H8GWIQ2ra69dsBdtqSWS-sA4lC1TG_xXT9OfaT3Moarz1tvNp8K_OPY2Rpp7HZOlZxaVlgMKyl3cZyirDU3NqTWLvCI1LmQiQJhiB1CtGQ4gvRSHYEq6nIx3hVaixVEQG1cX9egP__6up9np77IVd3w5iW-BrHSd3GaV6qU1zeq0Ma1WP_UcvPQwhfx1d8Ug) ## 5. Corbado vs Cognito - Core Differences Cognito and Corbado both support passkeys but they solve very different problems. Below is a breakdown of the most important distinctions across architecture, developer control, user experience and enterprise-readiness. ![aws cognito vs corbado passkeys](https://www.corbado.com/website-assets/aws_cognito_vs_corbado_passkeys_e9fbe4b42d.png) Cognito is a good fit for general-purpose identity provider (IdP), especially fits in small to medium-sized deployments that don’t require integration with existing user bases. Cognito focuses on helping developers authenticate users via passkey login, typically in standalone applications. [Corbado Passkeys](https://www.corbado.com/blog/passkey-performance-testing) are a better fit for custom frontend environments where high passkey adoption is critical. Corbado acts as a frontend-focused passkey layer that integrates seamlessly with existing identity systems like Cognito, in-house solutions or other third-party IdPs. It is optimized for reducing MFA costs and friction by enabling smooth, native passkey login in existing apps without requiring user migration. ### 5.1 Architecture & Role in the Stack | **Feature** | **Cognito** | **Corbado** | | -------------------- | -------------------------------- | ------------------------------------------------------------------- | | Role | Full Identity Provider (IdP) | Passkey orchestration layer | | Deployment model | Hosted UI / Managed Login or SDK | Integrated with any existing IDP | | Backend requirements | AWS-native | Works with Cognito, Keycloak, custom, etc. | | User storage | Cognito user pool | Reuses existing user IDs from e.g. Cognito user pool (no migration) | ➡️ Corbado is not an IdP. It enhances whatever identity provider you already use. ### 5.2 Frontend Integration & Developer Control | **Feature** | **Cognito** | **Corbado** | | ------------------------------- | ---------------------------------------- | ------------------------------------ | | UI Customization | Limited (Hosted UI / Managed Login only) | Full (custom UI + SDKs) | | Conditional UI | ❌ Not supported | ✅ Fully supported | | Device + browser fallback logic | ❌ Manual (user decides) | ✅ Smart fallback orchestration | | One-tap login | ❌ No | ✅ Supported via metadata + autofill | ➡️ Corbado gives you control over the entire passkey UX flow - including fallback paths and edge case handling. ### 5.3 Passkey Adoption & User Behavior Optimization | **Feature** | **Cognito** | **Corbado** | | ------------------------------- | ------------------------ | -------------------------------------- | | Inline passkey registration | ❌ Account settings only | ✅ Integrated into login, signup, etc. | | A/B testing support | ❌ | ✅ Included in developer console | | Drop-off tracking & funnel data | ❌ | ✅ Detailed per user / device | | Login method optimization | ❌ | ✅ Dynamic based on metadata | ➡️ Cognito implements passkeys. Corbado turns them into a user-first login experience that actually gets adopted. The following screenshot show’s Corbado’s funnel analysis that helps to understand login paths and determine bottlenecks and other observability insights. ![corbado passkeys analytics funnel](https://www.corbado.com/website-assets/corbado_passkeys_analytics_funnel_5d9407b44e.jpg) ### 5.4 Compliance, Rollout and Scale | **Feature** | **Cognito** | **Corbado** | | -------------------------------- | ----------- | ----------------------------------------------------------------------------- | | Enterprise rollout support | ❌ DIY | ✅ Structured rollout tools (pilot, A/B) | | Multi-device support + detection | Limited | ✅ Includes synced vs. hybrid passkey dection and advanced passkey maangement | ➡️ Corbado was built for regulated, high-scale environments like banks or [government](https://www.corbado.com/passkeys-for-public-sector) agencies that have dedicated requirements to the supported device base and rollout. With Corbado's process search, you can look for specific login events and back trace the user’s and system’s behavior to fix bugs or provide better support. ![corbado process events search](https://www.corbado.com/website-assets/corbado_process_events_search_10e07bf20f.png) ## 6. Best Practices for High Passkey Adoption Implementing passkeys is only half the battle. The bigger challenge is getting users to actually **create** and **use** them. Based on Corbado’s real-world deployments - including [VicRoads](https://www.corbado.com/blog/vicroads-passkeys) - here are five proven strategies to maximize passkey adoption. ### 6.1 Don’t hide Passkey Creation in Account Settings Offering passkey setup in the account settings might tick a feature box, but adoption will be low. Most users never explore settings and those who do won’t understand what a passkey is or why it matters. ✅ **Do this instead**: Prompt [passkey creation](https://www.corbado.com/blog/passkey-creation-best-practices) right after login or after successful signup, when the user is already authenticated and mentally primed to act. ### 6.2 Inline Passkey Prompts in the Login Flow Use [Conditional UI](https://www.corbado.com/glossary/conditional-ui) to **invoke passkey autofill as soon as the user clicks into the email input**. This mirrors what users are used to with password managers - seamless and invisible. ✅ This is supported in **most devices and browsers nowadays**. Corbado automatically detects support and enables the feature. ### 6.3 Intelligent Fallback Logic Not every device supports passkeys and not every user has created one yet. You need to handle: - First-time logins from users without a passkey - Devices which are not passkey-ready or lack certain WebAuthn features - Users switching between devices or ecosystems Corbado tracks metadata (device, browser, [user agent](https://www.corbado.com/blog/client-hints-user-agent-chrome-safari-firefox)) and dynamically selects the best method: - If a passkey exists: prompt with automatic passkey logins. - If not: fallback to password and conventional MFA via SMS or [authenticator](https://www.corbado.com/glossary/authenticator) apps but offer to [create a passkey](https://www.corbado.com/blog/passkey-creation-best-practices) afterward (if possible). ### 6.4 Optimize with A/B Testing Copy, placement and timing make a huge difference. “Sign in faster” performs better than “Use your fingerprint to log in simpler” performs better than “Enable passkey login.” Corbado’s developer console supports: - A/B testing login prompts - Tracking login times from passkeys and convetional login methods - Measuring drop-offs in the passkey funnel ✅ Use real data to iterate, not guesswork. [Watch on YouTube](https://www.youtube.com/watch?v=wnrXJzvBjsU) ### 6.5 Measure Everything Without visibility into how users interact with your passkey flow, you can’t improve it. Important metrics to monitor: - [Passkey creation rate](https://www.corbado.com/kpi/passkey-enrollment-rate) - Login success/failure rates - Device/browser compatibility - Top fallback methods Corbado provides a full analytics dashboard and even user-level traceability via the process search for debugging issues (e.g., failed logins due to outdated browsers). 👉 **Pro tip**: Treat passkey adoption like a growth funnel - just like signups or conversions. Plan for optimization cycles after your initial rollout. ## 7. Choosing the right Path: Cognito Passkeys or Corbado on Top of Cognito? If you're already using [AWS Cognito](https://www.corbado.com/blog/passkeys-amazon-cognito), you might be wondering: _Do I really need Corbado on top? Or is Cognito’s built-in passkey support enough?_ Here’s how to decide. ### 7.1 When to use Cognito Passkeys Cognito’s native passkey support is a good fit if: - You use the **Cognito Hosted UI / Managed Login** and don’t plan to customize it. - You're building a **greenfield app** and can design your flows around Cognito’s capabilities. - Your passkey needs are **basic**: you just want to offer passkeys as an _additional option_, not replace SMS or passwords entirely. - You don’t require **passkey tracking**, [conditional UI](https://www.corbado.com/glossary/conditional-ui), or A/B testing. - You’re okay with **manual user opt-in** (click a on a separate “Sign in with passkey” button) and don’t need a high passkey adoption. **Ideal for:**\ MVPs, internal tools (non-customer facing), B2B startups or dev teams prototyping with [AWS](https://www.corbado.com/blog/passkeys-amazon-cognito) Cognito. ### 7.2 When to Add Corbado on Top of Cognito Corbado becomes essential when passkeys are **not just a feature**, but a **strategic goal** - for security, UX or cost reduction. Use Corbado if: - You have a **custom frontend** (React, [Angular](https://www.corbado.com/blog/angular-passkeys), etc.) and need full control over UI and login logic. - You want to **automate passkey login** (conditional UI, [one-tap login](https://docs.corbado.com/corbado-connect/features/one-tap-login)) instead of relying on user clicks. - You’re aiming for **high passkey adoption** to reduce SMS costs or improve user retention. - You operate at **enterprise scale** - with millions of users and legacy login infrastructure (usually this implies thousands of different device, OS and browser (version) combinations. - You need **analytics**, **A/B testing** and **device-level fallback intelligence**. **Ideal for:**\ Enterprise apps, [government](https://www.corbado.com/passkeys-for-public-sector) platforms, high-traffic consumer portals or any business serious about moving toward a passkey-first future. ### 7.3 TL;DR: Use Cognito for basic Passkeys and Corbado for Enterprise Scenarios | **Use Case** | **Cognito Passkeys** | **Corbado + Cognito** | | ----------------------------------- | -------------------- | -------------------------- | | Basic passkey support | ✅ | ✅ | | Custom frontend integration | ❌ | ✅ | | One-tap login / conditional UI | ❌ | ✅ | | A/B testing & adoption analytics | ❌ | ✅ | | SMS cost savings / MFA optimization | ⚠️ (manual) | ✅ (automated + trackable) | | Gradual rollout | ❌ | ✅ | Corbado doesn’t replace Cognito - it makes it **enterprise-passkey ready**. ### 7.4 FAQ: Corbado vs. Cognito Passkeys #### 7.4.1 Can I use passkeys in AWS Cogntio without Hosted UI? Yes - but it requires manual integration. Corbado makes this easier by handling WebAuthn flows in your custom frontend. #### 7.4.2 What’s the difference between Corbado passkeys and Cognito passkeys? Cognito implements the basics. Corbado drives real adoption with fallback logic, A/B testing and full UX control. #### 7.4.3 Can I reduce SMS costs with passkeys on AWS? Yes - especially with Corbado, which optimizes passkey adoption to reduce reliance on [MFA fallback](https://www.corbado.com/faq/backward-compatibility-crucial-passkey-integration) like SMS. ## 8. Conclusion: Passwordless Authentication with AWS: Cognito vs Corbado Passkeys are quickly becoming the new standard of user authentication - but adopting them successfully requires more than just flipping a switch. While **Cognito passkeys** offer a solid starting point, they’re limited to basic use cases and Hosted UI / Managed Login flows. For teams that care about **adoption**, **UX optimization**, **fallback handling** and **enterprise rollout**, Cognito alone won’t be enough. That’s where **Corbado** comes in. By layering Corbado on top of Cognito (or any other IdP), you gain: - Higher passkey adoption rates - through better UX and smart fallback logic - Full integration into custom frontends - without vendor lock-in - Reduced MFA costs - especially for high-volume [SMS traffic](https://www.corbado.com/blog/sms-costs) - Analytics, A/B testing, and device intelligence - to continuously optimize your login flow In this blog post, we answered the following questions: 1. **What are the key differences between Corbado Passkeys vs Cognito Passkeys?**\ Cognito implements basic passkeys. Corbado optimizes adoption, UX and analytics for enterprise-scale use. 2. **When should you use Corbado Passkeys and when rather use Cognito Passkeys?**\ Use Cognito for basic needs with Hosted UI. choose Corbado if you have a custom frontend, large user base, or care about adoption and fallback flows. 3. **How can you increase the passkey user adoption if your IdP is Amazon Cognito?**\ Use Corbado to enable inline registration, conditional UI, fallback logic, analytics and progressive rollout. Whether you're building for millions of users or just starting your passkey journey, Corbado helps you go beyond “implementation” and achieve real outcomes. ## Frequently Asked Questions ### How do I add passkeys to a custom frontend using AWS Cognito? Adding passkeys to a custom Cognito frontend requires manually handling WebAuthn ceremonies, credential management and fallback logic, as [Cognito's](https://www.corbado.com/blog/passkeys-amazon-cognito) SDKs offer no out-of-the-box passkey orchestration for custom UIs. Corbado addresses this by providing frontend SDKs and UI components that integrate with Cognito as the identity provider without requiring user migration. ### What passkey adoption rate can I realistically expect from Amazon Cognito's native passkey support? [Cognito's](https://www.corbado.com/blog/passkeys-amazon-cognito) native [passkey button approach](https://www.corbado.com/faq/passkey-button-approach), which requires users to click a separate button to trigger login, produces a predicted [passkey login rate](https://www.corbado.com/kpi/passkey-usage-rate) of 1.4% after 36 months for a typical web application. Adding Corbado to the same environment raises that prediction to 47.5% after 36 months through inline registration, Conditional UI and smart fallback logic. ### What passkey analytics and observability does Amazon Cognito provide out of the box? Cognito provides no analytics on passkey registration success, drop-off rates or device and browser WebAuthn compatibility. Corbado fills this gap with a full analytics dashboard, per-user process search for debugging failed logins and funnel analysis covering [passkey creation](https://www.corbado.com/blog/passkey-creation-best-practices) rates, login success rates and top fallback method usage. ### When should I add Corbado on top of Amazon Cognito instead of relying on its built-in passkey support? [Cognito's](https://www.corbado.com/blog/passkeys-amazon-cognito) native passkeys suit MVPs, internal tools or greenfield apps using Hosted UI where basic passkey support without adoption optimization is acceptable. Add Corbado when you need a custom frontend, Conditional UI autofill, A/B testing, adoption analytics or [high passkey usage](https://www.corbado.com/blog/passkey-login-best-practices) rates to reduce SMS MFA costs at enterprise scale with millions of users.
