Make a pin code system

Make a pin code system.
My account once got hacked and the hacker banned everyone in the server.
Since people can use tokens to login they can bypass 2fa too. If there was something like a 4 digit pin that you could add (for example in roblox.) It would make it harder for hackers to access your account. 

Or it could just be a option for server moderators. You have to put a pin code before you can take any action.
