Need a fresh, hard-to-guess PIN? Pick a length and generate a random numeric PIN code in one click. Every digit comes from your browser's cryptographically secure random number generator, so the result is genuinely unpredictable — and because everything runs locally, your PIN is never sent, logged, or stored anywhere. Leave "Avoid obvious PINs" on and the tool will skip weak patterns like 1234, 0000, and simple sequences for you.

What makes a PIN weak

A PIN has far fewer combinations than a password, so the few predictable ones get tried first. Studies of leaked PINs show the same offenders every time. Steer clear of:

• 1234 and other sequences — by far the most common PIN in the world.
• 0000, 1111 and other repeated digits.
• Years (1990, 2024) and dates of birth — easy to guess or find.
• Patterns on the keypad like 2580 (straight down the middle) or 1379 (the corners).
• Anything you have used before on another card or account.

A random PIN avoids all of these. The generator's "Avoid obvious PINs" option rejects repeats, runs, and well-known weak codes automatically.

How long should a PIN be?

Longer is stronger. Each extra digit multiplies the number of possibilities by ten:

Length	Combinations	Notes
4 digits	10,000	The card standard — fine when lockouts limit guesses.
6 digits	1,000,000	A good default for phones and apps.
8+ digits	100,000,000+	Best where no limit on attempts applies.

Most bank cards use 4 digits because the chip or ATM locks after a few wrong tries, which keeps even a 4-digit PIN safe in practice. For phones, password-manager unlock codes, and anything an attacker could try many times, choose 6 digits or more.

Where you'll use a generated PIN

• Phone, tablet, and laptop lock screens.
• SIM cards and voicemail.
• Bank and credit cards (where you can set your own number).
• Door locks, alarms, and safes.
• App and password-manager unlock codes.

Tips for using PINs safely

• Use a different PIN for each thing. One leaked code shouldn't open everything.
• Never write it on the card or store it next to the device it unlocks.
• Shield the keypad when you type it in public.
• Prefer 6+ digits wherever the device allows it.
• Remember a PIN is not a password. For online accounts, use a long, random password from our password generator and store it in a manager.

Frequently asked questions

Are these PINs random and safe?

Yes. Each digit is drawn from crypto.getRandomValues(), the browser's cryptographically secure generator, with no bias. The PINs never leave your device.

Does my PIN get sent anywhere?

No. Generation happens entirely in your browser. Nothing is transmitted, logged, or stored, and your PIN is gone as soon as you close the page.

Is a 4-digit PIN secure enough?

For cards and phones that lock after a few wrong attempts, yes — the lockout does the protecting. Where attempts aren't limited, choose 6 or more digits.

Can I generate several PINs at once?

Yes. Use the counter next to the Generate button to create a batch, then copy them all or download them as a text file.
