Set min. password length?

Is there a way to set the minimum password length for new users?

I noticed that new users have by default a password generated with ~16 characters. That's already better than probably what most people use without password manager, however I'd like to increase that to 50 chars.

Once you go into tools -> pw generator and set the length there, it will keep that. However new users have only like 16 chars set by default.
