How to force account login for a single account user with Google's OAuth 2.0?

Question

Sometimes when a user logins into a site with Google\'s OAuth 2.0 they choose the wrong account to login with. Normally this isn\'t a problem if the user has more than one

Answer 1

Add the parameter prompt=select_account to your authorization request.

This will cause the account chooser to always be shown, even if the user is only logged in to one account. Users will be able to select from their accounts, or add a new one.

For example: https://accounts.google.com/o/oauth2/auth?redirect_uri=https%3A%2F%2Fdevelopers.google.com%2Foauthplayground&response_type=code&client_id=407408718192.apps.googleusercontent.com&scope=profile+email&access_type=offline&prompt=select_account
