Start integrating Smart Lock for Passwords into your Android app

Deprecated: Smart Lock for Passwords is deprecated. To ensure the continued security and usability of your app, migrate to Credential Manager today. Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience.

Before you start integrating Smart Lock for Passwords into your app, enable the Play Services SDK in your Android Studio project. Next steps describes how to integrate Smart Lock for Passwords into your app.
