How long should my PIN be?

A 6-digit PIN has 1,000,000 possible combinations, 100 times more than the 10,000 of a 4-digit PIN. Many phones now suggest 6 digits for the lock screen, while many bank cards still use 4. Use 8 digits (100,000,000 combinations) wherever the system accepts it; the length slider here goes from 4 to 8.

Are the PINs truly random?

Yes. Each digit is chosen with crypto.getRandomValues(), the browser's cryptographically secure random number generator. There are no patterns or predictable sequences.

Does the generator avoid weak PINs like 1234?

Each PIN is independently random, so common sequences are statistically very unlikely to appear. If you see a familiar pattern, click Generate another for a fresh one.

Can I generate several PINs at once?

Yes. The bulk section under the generator makes up to 100 PINs in one go, one per line, each drawn independently at the length set on the slider.

PIN generator

Generate a cryptographically random numeric PIN for device unlocks, account verification, or door codes. Choose between 4 and 8 digits. The PIN is built in your browser with its secure random number generator.

How it works

The tool uses crypto.getRandomValues(), the browser's built-in cryptographically secure random number generator, to select characters or words. No library is required and our servers are not involved. The password is generated entirely inside your browser tab.

Processing runs in your browser

All generation runs locally in your browser. The password exists only in your browser until you copy it. You can prove this yourself in your browser's DevTools Network tab. Once you copy a password, your operating system may keep it in its clipboard history or sync it to your other devices: Windows clipboard history and cloud clipboard, Apple Universal Clipboard or a clipboard manager. In a private window, Chrome, Edge and Firefox keep copies out of Windows clipboard history and cloud clipboard.

To share a Wi-Fi password without reading it out, use the Wi-Fi QR code generator. When you need random identifiers rather than secrets, use the UUID generator. To check that a copied key or file arrived unchanged, compare SHA-256 checksums with the hash generator.
