I cannot log in or have forgotten my password. What do I have to do?

If you cannot log in, this can have various causes. First, rule out all sources of error:

• Check whether your e-mail address and password are spelled correctly. Also ensure there is no password software auto-filling in incorrect passwords.
• Pay attention to upper and lower case and check whether the Caps-Lock key is active.

If you get stuck, you can request a new password.
