PIN length

Generate a random PIN

This tool creates random PIN codes for phones, cards, locks and app sign in. Choose a length of four, six or eight digits and how many PINs you need, then generate. With avoid weak PINs on, obvious codes are filtered out.

What makes a PIN weak

Weak PINs are the easy guesses: all the same digit like 0000, a straight run like 1234 or 4321, and a short list of very common codes. The tool skips these when the option is ticked, so every PIN it keeps is harder to guess than the defaults most people reach for.

Fair and private

Each digit comes from the browser cryptographic random source, the same source used for security keys, so the PINs are unpredictable. Nothing is sent anywhere, and the codes exist only in the page until you copy or clear them.

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.
