Boost your app's user experience by seamlessly integrating passwordless authentication with passkeys using Credential Manager. Credential Manager is an Android Jetpack library that unifies API support for most major authentication methods, including passkeys, passwords, and federated sign-in solutions (such as Sign-in with Google).
Credential Manager automatically displays a unified bottom-sheet for modern authentication methods, and is the modern replacement for existing authentication implementations, including Smart Lock for Passwords on Android, and One Tap. Credential Manager's unified sign-in interface gives your users a clear, familiar, and consistent experience, reduces churn and improves registration and sign-in speeds.
