PIN Generator

Generate cryptographically random numeric PINs from 4-12 digits.

Generate batches of numeric PIN codes from 4 to 12 digits using crypto.getRandomValues. Useful for generating one-time codes, locker codes, vault PINs and bulk activation codes that won't be guessable.

Common use cases

  • Generate locker, safe and door-keypad PINs
  • Mint bulk activation codes for products and giveaways
  • Create one-time-use access PINs for guests
  • Replace easy-to-guess PINs like 1234 or birthdays

Frequently asked questions

Are these PINs secure?
Yes — they come from crypto.getRandomValues, the same source browsers use for cryptographic keys.
How long should my PIN be?
4 digits gives 10,000 combinations (fine for low-stakes locks), 6 digits gives a million, and 8+ digits is appropriate for anything sensitive.
Can I get the same PIN twice?
Generated PINs are independent, so duplicates within a single large batch are possible. For unique-only batches, generate a few extra and de-duplicate.
