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 on Android. For iOS, it uses Keychain for storing credentials.

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.

For iOS, it uses Keychain and Autofill.

For more information, please refer to the official documentation.

Credential Flow Previews

Heads-up: The screenshots above come directly from the official Android and Apple design resources. The bundled example application recreates similar flows but may look slightly different depending on your theme, device, or customizations.

Development Workflow

We rely on pre-commit to guarantee formatting and analyzer checks run before every commit.

pip3 install --user pre-commit   # first time only
python3 -m pre_commit install    # installs the git hook
# (optional) run on the entire repo once
python3 -m pre_commit run --all-files

The configured hooks will:

• Format every staged Dart file using dart format.
• Format docSite sources with Prettier.
• Run flutter analyze across all packages (including the example app); commits are blocked if any analyzer error occurs.
