Built the same way as our password generator

Cryptographically secure, private, and free — with no account required.

Cryptographically secure

Powered by the Web Crypto API instead of predictable pseudo-random functions.

Pattern-aware

Optionally avoid repeating and sequential digits — the first patterns anyone tries when guessing.

Private by design

PINs are generated locally on your device and never transmitted or stored.

Frequently asked questions

Everything you might want to know about the PIN generator.

It depends on what it protects. Four digits is a common minimum for device lock screens, but six digits is increasingly standard and offers a meaningfully larger set of combinations. Use the longest PIN the device or service allows.

It prevents runs like 1234 or 4321 from appearing anywhere in the PIN. Sequential runs are among the first patterns guessed in a manual attempt, so avoiding them removes an easy shortcut.

Generally yes. People tend to reuse birthdays, repeated digits, or simple patterns, all of which are tried first in a guessing attempt. A randomly generated PIN has no such pattern to exploit.

No. Every PIN is generated locally in your browser using a cryptographically secure random source, and nothing is ever sent to a server or logged.
