Smart Lock for Passwords on Android

By integrating Smart Lock for Passwords into your Android app, you can automatically sign users in to your app 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.

See some case studies of successful Smart Lock for Passwords integrations.

Store user credentials with Auth.CredentialsApi.save():

Auth.CredentialsApi.save(mCredentialsClient, credential).setResultCallback(
  new ResultCallback() {
      @Override
      public void onResult(Status status) {
          if (status.isSuccess()) {
              // Credentials were saved
          } else {
              if (status.hasResolution()) {
                  // Try to resolve the save request. This will prompt the user if
                  // the credential is new.
                  try {
                      status.startResolutionForResult(this, RC_SAVE);
                  } catch (IntentSender.SendIntentException e) {
                      // Could not resolve the request
                  }
              }
          }
      }
  });

Retrieve stored credentials with Auth.CredentialsApi.request():

Auth.CredentialsApi.request(mCredentialsClient, mCredentialRequest).setResultCallback(
  new ResultCallback() {
      @Override
      public void onResult(CredentialRequestResult credentialRequestResult) {
          if (credentialRequestResult.getStatus().isSuccess()) {
              // Handle successful credential requests
          } else {
              // Handle unsuccessful and incomplete credential requests
          }
      }
  });
