I was trying to add my ssh key to BitBucket and it complained that somebody was already using that key. That can only be me so it must be in one of my accounts.
Checking my password manager, I have a couple of other accounts here but they only have bitbucket.org user IDs. Not id.atlassian.com email addresses.
Is it possible to login to those accounts? Or can an atlassian person trigger an email to an associated email address or something? I have the user ID and password. But there's nowhere I can use it.
