PIN Generator

How to use

1. 1Choose a PIN length with a preset like 4 or 6, or use the slider for 3 to 12 digits.
2. 2Set how many PINs you want, from a single code up to 50 at once.
3. 3Optionally turn on rules to avoid repeats, runs like 1234, or a leading zero.
4. 4Click Generate PINs to create the codes from your browser's secure random generator.
5. 5Copy a single PIN, copy one row from a batch, or copy all codes at once.

About this tool

PIN Generator creates random numeric personal identification numbers entirely in your browser. Each digit is drawn from crypto.getRandomValues, the browser's cryptographic random source, using rejection sampling so every digit from 0 to 9 is equally likely; a naive modulo would slightly favour the lower digits, and this tool avoids that bias. Set the length anywhere from 3 to 12 digits, with one-tap presets for the common 4, 5, 6, and 8 digit formats used by bank cards, phone locks, alarm panels, door keypads, lockers, and SIM codes, and generate up to 50 codes at once when you need a batch for a class, a team, or a set of devices. Three optional rules help you steer clear of codes that are easy to guess: no repeated digits keeps every position distinct, no runs or all-same skips straight sequences like 1234 or 8765 along with constant codes like 0000 and 7777, and no leading zero forces the first digit to be 1 through 9 for systems that silently drop a leading zero. When you ask for distinct digits on a PIN longer than ten characters, which is mathematically impossible because there are only ten digits, the tool clearly flags that the rule was relaxed rather than failing or looping forever. A single PIN is shown large and spaced for easy reading with a copy button, and a batch is listed in a grid with per-code copy plus a copy all action. The possible-combination count for the chosen length is shown as a rough guide to guessability: a 4 digit PIN has 10,000 combinations while a 6 digit PIN has 1,000,000, which is why many systems are moving to longer codes. Note that a PIN is a short numeric code and is not a substitute for a full password; for logins use a long random password or a passphrase instead. Generation, the secure randomness, and every option run locally. Your settings and the codes you create are never uploaded, never logged, and disappear when you close the tab.
