PIN Generator – Create Secure Number PINs
From bank cards to SIM cards, door locks, and safes, PINs are everywhere. But a lot of people still pick birthdays, anniversaries, or easy patterns like 1234. That's a real security risk, and a good PIN generator makes it easy to avoid.
This tool creates cryptographically random number sequences right in your browser. You set the length (4 to 12 digits), how many you want, and whether to skip sequential or repeated digits. It uses crypto.getRandomValues(), and no generated PIN is transmitted to our server.
Which PIN length works best
- 4-digit PINs (10,000 combinations) are fine for everyday phone locks but weak against online attacks
- 6-digit PINs (1 million combinations) are the standard for bank cards and offer a good balance of security and memorability
- 8 to 12-digit PINs for secure locks, safes, or administrative access
Common PIN mistakes
- No birthdays, years, or anniversaries
- Sequential digits like 1234 or 5678 are too easy to guess
- Repetitions like 1111 or 9999 are the first thing attackers try
- Your SIM PIN should differ from your bank card PIN
- Don't store PINs on your phone or write them on the card
Frequently asked questions
Which PIN length is the most secure?
Six-digit PINs are the standard for bank cards and strike a good balance between security and memorability. For locks, safes, or administrative access, 8 to 12 digits are recommended because they produce far more combinations.
What does the option against sequential digits do?
It prevents sequences like 1234, 5678, or 3456. Such patterns sit at the very top of the list attackers try first. With it enabled, the generator only produces PINs whose digits do not follow each other directly.
What does the option against repeated digits do?
It excludes PINs with repeated digits such as 1111, 0000, or 9999. These repetitions are also very easy to guess. Enable the option if you want to be sure to avoid such patterns.
Can I exclude individual digits?
Yes. You can enter specific digits that should not be used. This is handy when certain numbers feel uncomfortable to you or a digit is already used elsewhere.
Can I generate several PINs at once?
Yes. Besides the length, you set the desired quantity. The generator then creates several independent PINs so you can freely pick one of them.
Where are my PINs stored?
Nowhere. All PINs are generated in your browser with crypto.getRandomValues() and never leave your machine. There is no transmission and no storage.
