I registered a new openhab server in my new myopenhab cloud account.
For this admin login I used a mail address like ‘email@example.com’. The registration was successful and I could verify my account and already add a new regular user.
But if I try to login with my credentials again I only get the error message ‘Unknown user or incorrect password’.
The regular user still works fine (which has no ‘+’ in the mail address) but my admin user is kind of lost.
Is there a way to login again with my admin user or change the mail address in the system?
