ULX - When a staff member joins they need a pin to get the group

The title says all but I want the min and max to be 6 NUMBERS only numbers.

When they get the rank for the first time (they have to be online) they need to type in their own code.

If you can a command for it to change or remove or add a pin would be good so I can change it if the account gets compromised.

Thanks in Advanced - Anthony

P.S. I don’t know if this is the right forum for it.

Laughable. This will require using a database. Also the time and effort to create something so trivial for, what I’m assuming is, yet another garbage RP server. Good luck finding someone to do this just for you… for absolutely nothing in return.
You should hire someone on trashfodder. https://scriptfodder.com/jobs/
