Where do I find the exact requirements of the password strength per category? (None/Weak/Fair/Good/Strong/Very Strong) And is there an option to exclude common passwords like "Password1" and the customers name, etc?
I think in the php code which implements the restrictions, though you might find a summary by searching the forums here (I don't remember one specifically, but it's possible). I believe no, and in searching I only find one feature request related to that: https://git.ispconfig.org/ispconfig/ispconfig3/issues/2969 You might login there, add additional clarification/suggestions for implementation, and give it a thumbs-up.
