The password must comply to the password guidelines:

• At least 12, better 16 characters (max. 127 characters).
• The password must contain at least three of the following character types:
  • Uppercase letters (A-Z), not ÄÖÜ etc.
  • Lowercase letters (a-z), not äöüß etc.
  • Numbers (0-9)
  • Special characters: !"#%()*+,-./:<=>?@[\\]_{|}~
• Not allowed: &\$^`; as well as space and apostrophe.
• The password must not be derived from your name, username or a dictionary word.

One possibility is to choose the first letters of the words from a sentence, e.g. from a saying, song or poem. Alternatively, feel free to combine several words or word fragments into one long password.
