Members of University of Hamburg (regular students, employees) use their uni username to log into CommSy. You can change your password in your account settings.
People who are not members of University of Hamburg can also be given access to CommSy. This includes individuals working on a joint research project with members of Universität Hamburg, for example. They can be invited by their project partners.
If you are still using the “CommSy” source to log in with your old account, you can use the link “Forgot your password?” to change your password.
Do not confuse this with: password, membership code
Tip: Read the tutorial “First steps” to learn more about logging in to your account.
