Web and Android developers can implement credential sharing to simplify the
sign-in experience for their users.
Seamless credential sharing allows Google Password Manager and
other identity technologies to securely share credentials across websites and
Android apps. This simplifies the sign-in experience, as Google Password Manager
can automatically populate user credentials on your websites and apps.
To declare that your Android apps and websites can share credentials:
- Host a Digital Asset Links (DALs) JSON file on your websites declaring
a credential sharing relationship.
- Declare your Android app's ability to share credentials in your app's
manifest.
After Google verifies your declared credential sharing configuration, it
suggests saved credentials to users, streamlining account management tasks
(sign-up, sign-in, password changes, and password resets) across all linked
platforms.
