I'm trying to login to firebase using login credentials of, say, User-Alice.
But when I go through the authorization procedure I get a message saying I'm logged in as User-Bob. This is not mentioned anywhere in the documentation nor does it explain how to change the user I'm logged in as.
How can I change the Firebase logged in user from User-Bob to User-Alice?
The easiest way to handle this is to logout User-Alice and the login User-Bob.
firebase logout
firebase login
But, if you're logged as User-Alice with a Google account in the browser you'll need to sign out there first.
