[Feature Request]: Allow Longer and More Complex PINs/Passwords

[aRandomMenno]

Currently, the application only allows for a 4-character PIN. This is a bit short and could be easier for someone to guess.

I'd like to suggest adding the ability to create longer PINs or passwords. This would make it much harder for someone to guess and improve security.

It would be awesome if we could also use letters (both uppercase and lowercase) and special characters (like !@#$%^&*) in these PINs/passwords. This would make them even stronger and give users more choices.
