This article will cover the Google One Tap login with Auth0.

• Google One Tap Login

Unfortunately, at this time, Google One Tap is not fully supported. Until this is supported "out of the box" a redirect flow will be required:
 

1. Retrieve the email for the user from the Google id_token.

2. Call the tenant's /authorize endpoint with login_hint=<email> and connection=google-oauth2.

3. Users are redirected to Auth0, then Google, and given there’s an existing Google session, they get redirected back to the application automatically.
