PIN Generator
Generate a random numeric PIN of any length — for a card, a lock, an alarm, or any code where only digits are allowed. Pick the number of digits, generate one or several at once, and copy the one you want. It's all made securely in your browser.
Adjust the options to generate a result.
Generated in your browser with the device’s secure random generator (Web Crypto). Nothing you generate is sent to a server, saved, or put in the page address — copy it somewhere safe.
Choosing a length
A PIN is just digits, so its strength comes entirely from how many there are:
- 4 digits — 10,000 possible combinations
- 6 digits — 1,000,000 possible combinations
Every extra digit multiplies the possibilities by ten. Where you get to choose, 6 digits is a sensible minimum, and more is better for anything that an attacker could try many times.
Avoiding a weak PIN
The problem with human-chosen PINs is that people pick memorable ones, and "memorable" is exactly what's easy to guess:
- Dates — birth years and
MMDDbirthdays - Repeats —
0000,1111,2222 - Sequences —
1234,4321 - Keypad shapes — patterns you can draw with a finger
A random PIN has none of these tells. This generator draws each digit independently and without bias, so 1234 is exactly as likely as any other combination — and no more guessable.
Where a PIN fits
A PIN is right when the input only takes digits — a phone lock, a bank card, a door code, an alarm panel. When the system allows letters and symbols, a full password or passphrase is stronger for the same length; use the password generator there. For a PIN, pick as many digits as the device allows, generate, and copy.
Made on your device
Need a few to choose from, or PINs for several devices? Set the count and generate a batch at once. Every one is created in your browser with its secure random generator — nothing is sent anywhere, so the code is only ever on your screen.
Frequently asked questions
How many digits should a PIN be?
More digits means harder to guess. A 4-digit PIN has 10,000 possible combinations; a 6-digit PIN has 1,000,000 — a hundred times more. Use at least 6 digits where the option exists, especially for phones and anything that isn't rate-limited to a few tries. This generator supports 3 to 12 digits.
What makes a PIN weak?
Predictability. Dates (1990, birthdays), repeats (0000, 1111), sequences (1234), and patterns you can trace on a keypad are the first things anyone tries — a handful of common PINs cover a large share of real ones. A randomly generated PIN avoids all of that, because every digit is an independent, unbiased draw with no pattern to guess.
Is this PIN generator secure?
Yes. Each digit comes from the browser's secure random number generator (the Web Crypto API), drawn without bias so no combination is favored over another. Nothing you generate is sent to a server, saved, or written into the page address — it exists only on your screen until you copy it.
