My account:
I have done a password reset, and carefully verified that the password was correct but still get:
Invalid login or password.
I suspect something is broken on the gitlab.com backend that has glitched my account so I can’t log in.
Can anyone help?
Nobody here can help, this is community forum, so we don’t have any Gitlab admin rights to do anything like that.
You can try opening a support ticket though: https://support.gitlab.com/hc/en-us/requests/new?ticket_form_id=360000803379
Amusing. The support ticket system suggested I post here. 
For all other inquiries, we advise searching for and posting your question in our community forum.
