Why this PIN is safe
Generate a PIN to see the checklist.

Check it against the same common-PIN and pattern database this generator avoids.

Random digits alone aren't enough
Picking 4 random digits sounds safe, but roughly 5–7% of the raw 4-digit keyspace is exactly the kind of PIN people already overuse —
1234, 0000, birth years, repeating pairs, keypad lines like 2580. A generator that just calls a random-number function can hand you one of those by chance. This one doesn't stop at "random" — every candidate PIN is checked against the same nine pattern rules used by our PIN Strength Checker, and re-rolled until it passes all of them.
Longer is stronger. If your device supports it, a 6-digit or 8-digit PIN is dramatically harder to brute-force than a 4-digit one — a 4-digit PIN has 10,000 possible combinations, a 6-digit PIN has 1,000,000, and an 8-digit PIN has 100,000,000. Everything here runs locally in your browser using the Web Crypto API's cryptographically secure random number generator — your generated PIN is never sent anywhere.
