After integrating with GMail I can't no longer login as our system administrator accout as it is a mail group and not a real GMail user. However I can enter without problems at atlassian.com
I think that creating a real gmail account may resolve the problem, but I don't want this, I prefer to enter by password or migrate the system-administrator rigth to other user.
When I try to recover username using any email of our corporation it says that the mail doesn't exit, also trying to recover password by username says that this username doesn't exist.
