Hi We've just migrated off GSuite, but I don't understand how to convert users from Google Account authentication to normal Atlassian email user accounts.
Hi James and welcome to Atlassian Community!
I'm not sure if I understood correctly, is it related to the option "Login with Google" that users see on the login page?
If it's not, can you please give us more details about what would you like do to? What is the behaviour that users are facing on the authentication?
