Don't let crooks 'rune' your day

I didn't know this (because I don't play the game myself) but the game Runescape has a game mechanic known as a bank where you can store in-game items, and each player's bank can be protected by a PIN which can either be a 4-digit code that you choose, or a 6-digit one-time-passcode returned from an authenticator app for the game. Essentially, the game has a sort of 2-factor authentication.
