Characters for Passwords, Network Keys and Names

When defining passwords (security codes), keys and names, not all characters are allowed, and not all passwords are secure. This is why the FRITZ!Box assists you in assigning secure passwords, for instance when creating new users or configuring MyFRITZ!. A diagram indicates how secure the chosen password (security code) is.

When assigning passwords, network keys and names, take note of the following guidelines and lists of available and illegal characters.

Note:When they are defined, passwords are depicted in clear text. Once they have been saved, every time they are entered they will be displayed encoded.
