PIN Generator
Create random 4- to 8-digit PINs with your browser's cryptographic generator, several at a time, while skipping the combinations everyone tries first.
Why these PINs are truly random
This generator uses crypto.getRandomValues, the cryptographic random number generator built into your browser: the same kind of randomness source used for encryption keys, and far less predictable than Math.random or human imagination. People, in fact, keep picking the same codes: studies of leaked PINs show that 1234, 1111 and 0000 alone account for nearly 20% of all 4-digit PINs, followed by birth dates and years. A randomly generated PIN appears on none of those guess lists.
4, 6 or 8 digits: how much does it matter?
Every extra digit multiplies the possible combinations by ten: 10,000 for a 4-digit PIN, 1 million at 6 digits, 100 million at 8. For your SIM card or debit card the length is set by the issuer, but wherever you get to choose (phone lock screen, safes, alarm systems) 6 or more digits give you noticeably better protection. The "skip obvious sequences" option discards codes made of identical, repeated or consecutive digits — exactly the ones anyone would try first. And remember: never reuse the same PIN across different services.
