Changing your Wi-Fi and OPAC Password

In order to use our Wi-Fi we request a secure password. Since the Wi-Fi login uses your user account, a one-time password change is required.

  • Your old password is either your initial password or (if already changed) your OPAC password.
  • Your initial password is your date of birth in the format ddmmyy.
  • Your new password is not only valid for Wi-Fi but for all account services, including OPAC.

The new password should contain at least six and at most 32 characters, including at least 1 alphabetical character, 1 numerical character, 1 special character.

Permitted characters:

  • alphabetical: Aa … Zz
  • numerical: 0 … 9
  • special characters , ; . : – _ # ' + * ! " $ % & / ( ) = ?

Please note: Your new password can be used immediately to log in into your user account. Wi-Fi login may require a waiting period of 30 minutes.

If you cannot change your password here, e.g. in case you forgot your password, you can request a password reset at the help desk.

Password Reset by Email

In case you allowed us to store your email address, we can use it to reset a forgotten password:

Please enter your user card number and your deposited email address into the form.

On successful validation we send you an email containing a password reset link. You should use this link within one hour to reset your password.

Please note: Your new password can be used immediately to log in into your user account. Wi-Fi login may require a waiting period of 30 minutes.
