Random PIN Code Generator
Generate random PIN codes in your browser. Four, six or any digit length, with weak PIN filtering so you never get 1234 or 0000.

How to use the PIN generator
- Choose a length of 4, 6 or 8 digits.
- Leave Avoid weak PINs on, and tick Avoid year PINs to skip 19xx and 20xx codes.
- Generate one PIN or a batch, then copy what you need.
What is a PIN code generator
A PIN code generator creates random PINs of four, six or any digit length, entirely in your browser. Weak PIN filtering is built in, so obvious sequences like 1234 or 0000 are skipped, which makes it a quick way to set a card PIN, a lock code or a fresh number you can actually rely on.
Why common PINs like 1234 are unsafe
A famous analysis by DataGenetics of 3.4 million leaked four digit PINs showed how predictable human choices are. The single code 1234 covered about 11 percent of everything, and the concentration at the top is startling:
| PIN | Share of all PINs in the leak |
|---|---|
| 1234 | about 11% |
| 1111 | 6% |
| 0000 | 2% |
| The 20 most common together | over a quarter of all PINs |
| 8068, the least common | under 0.001% |
An attacker allowed a handful of guesses starts with that table, which is why a guessable PIN fails long before brute force enters the picture. The study also found a dense band of PINs starting 19, people using birth years, which is exactly what the avoid year PINs option here filters out.
Why a random PIN is harder to guess
A uniformly random 4 digit PIN is one of 10,000, so three guesses succeed 0.03 percent of the time against it, against better than 1 in 5 for the top guesses table above. Six digits widen the space to a million codes and eight digits to a hundred million. Every PIN this page produces is drawn from the cryptographic source, then filtered against the weak list and, optionally, the year band, so what remains is the flat, patternless space an attacker cannot shortcut.
How to store and use a PIN safely
Generate it here, set it on the card, phone or lock, and store the note in a password manager rather than a wallet. Nothing typed or generated on this page leaves your device. For one time login codes rather than a durable PIN, use the OTP code generator.

Frequently asked questions
What PIN lengths can I make
Four, six or eight digits, covering bank cards, phones and most locks. Generate one PIN or a batch at once.
What does avoid weak PINs do
It skips obvious codes such as 0000, 1234 and other common or sequential PINs, so the result is harder to guess.
Are the PINs random
Yes. Every digit is drawn from the browser cryptographic random source, so PINs are unpredictable and do not follow a pattern.
Do the PINs leave my device
No. They are generated in your browser and nothing you see is sent to a server.
Is it free
Yes, free and with no sign up.
