Configuring Sign-In with Google

To use sign-in integrations with Google, you must create a Google Developer Project and API credentials. You can do this using your existing Google account. Users will only see the app name that you define. They will not see anything relating to the account that you use to create the app.

You can’t change the Google account under which you create the app without requiring users to reauthenticate and re-link their accounts.
