I've forgotten my username. What now?
If you cannot remember your username, use the button labeled “Forgot your username?”. It is underneath the entry field for your username in the CommSy bar on the room overview page. After clicking the button, enter your email address. You will receive an email listing the usernames that are connected to your email address.
Note: This only works for local usernames that use “CommSy” as an authentication source. If you are a member of Universität Hamburg and you log in to the system with your uni username, use the account administration to change your password.
