To ensure the continued security and usability of your app, <a href="https://developer.android.com/training/sign-in/credential-manager/">migrate to Credential Manager</a> today. Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience. For Wear developers: Credential Manager will be supported in Wear OS 5.1 and later on selected watches. Developers actively supporting Wear OS 3, 4 and 5.0 devices with Sign in with Google should continue using Google Sign-in for Android for your Wear applications. Sign in with Google support will be available on Credential Manager APIs for these versions of WearOS at a later date. </aside> <p>Before you can start integrating Google Sign-In in your own app, you must configure a Google API Console project and set up your Android Studio project.
