PIN Generator
Generate random numeric PINs of any length, with an option to skip weak, obvious codes.
About the PIN Generator
The PIN Generator creates random numeric PINs — the short codes you use for phone locks, debit and credit cards, SIM cards, voicemail, door locks, alarm panels, and two-step verification apps. You choose how many digits each PIN has, generate as many as you need at once, and optionally skip the obvious, easily guessed combinations. Every PIN is produced by your browser's built-in cryptographic random number generator (crypto.getRandomValues), the same class of randomness used for real security work, and nothing is ever transmitted or stored.
People are surprisingly predictable when they pick PINs by hand. A handful of codes — 1234, 0000, 1111, 1212, birth years — account for a huge share of every four-digit PIN in use, and those are the first ones an attacker tries. Letting a machine draw the digits removes that human bias, so your PIN is just as likely to be 4791 as 1234, and no more guessable than pure chance allows.
How to use
- A fresh PIN appears automatically when the page loads. Click ↻ or Regenerate any time for a new one.
- Set the PIN length with the slider, from 3 to 12 digits. Four digits is the common default for cards and phones; six or more is stronger and increasingly required.
- Choose how many PINs to generate at once — from 1 to 50 — which is handy when you need distinct codes for several accounts or devices.
- Keep "Avoid obvious/sequential PINs" turned on to reject trivially weak draws such as
0000,1111,1234, or9876. Turn it off if you truly want an unfiltered random draw. - Click Copy PIN (or Copy all for a batch) and paste the code where you need it, then store it in your password manager.
Longer PINs are dramatically harder to guess: a 4-digit PIN has 10,000 possible values, while a 6-digit PIN has a million and an 8-digit PIN a hundred million. Use the longest length the system will accept.
Frequently asked questions
Are these PINs really random and safe?
Yes. Each digit comes from crypto.getRandomValues, the browser's cryptographically secure random generator, combined with rejection sampling so every digit from 0 to 9 is equally likely. This is genuinely unpredictable randomness, not the weak Math.random() used by many web toys.
Is my PIN sent to a server or saved anywhere?
No. Generation happens entirely in your browser with JavaScript. The PIN is never uploaded, logged, or stored — not even by us. Once you close or refresh the page it's gone, so copy it somewhere safe right away, ideally into a password manager.
What does "Avoid obvious/sequential PINs" do?
When it's on, the tool throws away any draw that is trivially weak: all identical digits (0000, 7777) or a straight ascending or descending run (1234, 9876). It quietly draws again until it gets a code without those patterns, so what you see is still fully random — just not one of the codes attackers guess first.
How many digits should my PIN be?
Use the longest the system allows. Four digits is the minimum for most cards and phones, but six or eight digits are far stronger and are becoming standard for phones and banking apps. Every extra digit multiplies the number of possible codes by ten.
Can I generate several PINs at once?
Yes. Set "How many PINs" up to 50 and the tool lists them together — useful for setting up multiple devices, accounts, or users at the same time. Use Copy all to grab the whole batch, with one PIN per line. A numeric PIN is still weaker than a full password, so for logins that allow letters and symbols use the password generator instead.
Do you store a history of generated PINs?
No. PINs are explicitly never saved, synced, or added to any history — by design, because a stored PIN is a PIN that can leak.
