In case of a lost/forgotten password rendering you unable to access your account, visit the School Office and ask that it be reset for you. Passwords cannot be sent via email.
If you have a working password and want to change it, go to Central Login, log in and proceed to change the password. The operation will result in a change of the password for both your email account and USOSweb. After the operation, allow a few minutes for the systems to sync.
