Description:

credential manager

Credential Manager #
Credential Manager is a Jetpack API that supports multiple sign-in methods, such as username and password, passkeys, and federated sign-in solutions (like Sign-in with Google) in a single API, simplifying integration for developers.
For users, Credential Manager unifies the sign-in interface across authentication methods, making it clearer and easier to sign into apps, regardless of the chosen method.

Note: This package is currently only supported for Android.
