Frequently Asked Questions

How secure is a 4-digit PIN?

There are only 10,000 combinations, so security depends entirely on the attempt limit. With three tries, the chance of a random guess succeeding is about 0.03% — but only if your PIN is genuinely random.

What are the most common PINs?

Analyses of leaked data consistently find 1234, 1111, 0000, 1212 and 7777 near the top, with roughly a tenth of all PINs being 1234 alone. Birth years starting 19 are also heavily over-represented.

Why avoid dates?

Because a birth year, birthday or anniversary drastically shrinks the search space and is often discoverable from social media. An attacker who knows you were born in the 1990s has only ten candidates to try first.

Should I use a 6-digit PIN instead?

Yes where the option exists. Six digits gives a million combinations rather than ten thousand — a hundredfold improvement for two extra keystrokes.
