App flip

App flip allows your users to easily and quickly link their accounts in your authentication system to their Google accounts. If your app is installed on your user’s phone when they initiate the account linking process, they are seamlessly flipped to your app to finish linking. This allows the linking process to finish faster, as your user does not have to enter a username and password to authenticate themselves.

Once a user has linked their Google account with your app, they can take advantage of any smart home integrations that you have developed.

This figure shows the steps for a user to link their Google account
            to your authentication system. The first screenshot shows how a user
            can select your app if their Google account is linked to your app.
            The second screenshot shows the confirmation for linking their
            Google account with your app.
