Why a random PIN matters

People pick PINs badly. Studies of leaked PIN data consistently find that a handful of codes, such as 1234, 0000, 1111 and birth years, account for a large share of all PINs. Someone trying the most common few dozen four-digit PINs will open a surprising number of phones and cards. A randomly generated PIN gives every code an equal chance, so those guesses get an attacker nothing.

How long should a PIN be?

A PIN is protected less by its length than by the lockout after a few wrong tries. A bank card or SIM blocks after three attempts, so even four random digits are hard to guess. Where you can choose, use six digits: it's a hundred times more combinations than four. For a phone, consider a full passphrase instead of a PIN, because a phone that falls into the wrong hands may face more sophisticated attacks than simple guessing.
