PIN Generator
Generate a random PIN, digits only.

How this works
Each digit is drawn with crypto.getRandomValues using rejection sampling, so every digit is equally likely. Adjust the length for a 4, 6 or longer PIN.
What the results mean
- Length matters most
- A 4-digit PIN is one of 10,000; a 6-digit is one of a million. Longer is exponentially harder to guess.
- No excluded patterns
- Every combination is equally likely, including 1234 and 0000. Excluding them would shrink the space and make the result marginally more predictable, not less.
Common problems and fixes
- It generated something like 1111 or 1234
- That is randomness behaving correctly — every four-digit combination has the same one-in-ten-thousand chance, including the memorable ones. Generate another if it makes you uncomfortable, but understand that a generator which filters out "bad-looking" PINs has made the remaining set smaller and slightly easier to guess.
- The system will not accept the PIN
- Some systems reject sequences, repeats or PINs matching part of your account details, and a few require a specific length. Generate another at the required length. If a system also forbids a PIN you can remember, that is a sign it is relying on the PIN for more security than a PIN can provide.
- I need something stronger than a PIN
- Then use a password. A six-digit PIN is one of a million combinations, which a computer exhausts instantly — its security comes almost entirely from the device limiting attempts and locking after a few failures. Anywhere that protection does not exist, digits alone are the wrong choice.
Frequently asked questions
Is a PIN as secure as a password?
No, and it is not meant to be. A PIN’s security comes largely from the device limiting guesses and locking after a few tries, not from the PIN itself. For anything protected by guessing alone, use a full password, which has vastly more entropy.
Are four digits enough?
Only when something limits the guesses. A phone that locks after ten attempts makes a four-digit PIN reasonable; a system that allows unlimited tries makes it worthless, since ten thousand combinations take no time at all. Six digits is a hundred times better and still trivial without rate limiting — the lockout is the real protection.
Should I avoid using a date?
Yes, particularly a birthday or an anniversary. Analyses of leaked PIN sets show dates dominate the most common choices, which is why attackers try them first, and yours is often discoverable. A random PIN of the same length is enormously harder to guess for exactly the same amount of typing.
