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 using your browser's secure random number generator and stays in your browser.
Bulk generation
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 yourselfin your browser's DevTools Network tab.

For hashing the generated secret for storage, try the hash generator. To create random opaque identifiers instead, use the UUID generator. For encoding generated tokens for transport, see Base64.
Frequently asked questions
How long should my PIN be?
6 digits is the modern minimum for phone unlocks and bank cards (1 million combinations). 4 digits is the legacy minimum and is still common but easier to guess. 8 digits is a good choice for high-value accounts.
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 again for a fresh one.
Is the PIN sent to a server?
All generation runs in your browser using crypto.getRandomValues(). The PIN is never logged or transmitted to any server.
