With the Smart Lock for Passwords API, you can programmatically save and retrieve credentials, and automatically sign users in across devices and websites in Chrome.
Smart Lock for Passwords can be integrated into an Android app, allowing user to automatically sign using the credentials they have saved. Users can save both username-password credentials and federated identity provider credentials.
Integrate Smart Lock for Passwords into your app by using the Credentials API to retrieve saved credentials on sign-in. Use successfully retrieved credentials to sign the user in, or use the Credentials API to rapidly on-board new users by partially completing your app's sign in or sign up form. Prompt users after sign-in or sign-up to store their credentials for future automatic authentication.
