More about this tool

The PIN Generator creates numeric PIN codes of a chosen length directly in your browser. It is useful for temporary access, demo accounts, test data, UI mockups, local workflows, and quick one-time codes. You can set PIN length, the number of codes, whether leading zeros are allowed, whether digits may repeat, whether duplicate PINs are allowed in a list, and whether obviously weak combinations are excluded. Generation runs locally in your browser, and your data is not sent to the UtiLab server. Do not use a PIN as the only protection for an important account.

Frequently Asked Questions

How do I generate a PIN?

Set the PIN length, choose how many codes you need, and click Generate. You can copy the result with one click.

Can a PIN start with zero?

Yes, if "Allow leading zero" is enabled. For example, PIN 0427 should display and copy as 0427.

Can I generate several PINs at once?

Yes. Enter the number of PINs, and the tool creates a list you can copy as a column, comma-separated values, or JSON.

Can I forbid repeated digits inside a PIN?

Yes. Enable the no-repeat mode. For example, 1234 is allowed, but 1123 is not.

Can I exclude weak PINs?

Yes. The tool can exclude obvious combinations such as 0000, 1111, 1234, 4321, and repeating patterns.

Is my data sent to the server?

No. Generation runs locally in your browser and is not sent to the UtiLab server.

Can I use this PIN to protect an account?

A PIN is fine for temporary access, demos, and tests, but it should not be the only factor protecting an important account.

What is the difference between crypto random and Math.random?

Crypto random uses the browser cryptographic random source when available. Math.random is used only as a fallback when crypto random is unavailable.

Why is a PIN copied as a string, not a number?

A PIN may start with zero. If you store it as a number, the leading zero is lost. Treat a PIN as a string.

Do I need to register?

No. The tool works immediately without registration.
