Generate a random PIN code with 4, 6, or 8 digits. Created in your browser — your PIN is never sent to a server. Free, instant, private.

Most people pick weak PINs. The most common 4-digit PIN in real-world data leaks is 1234, followed by 1111, 0000, and 1212 — together those four codes cover roughly 20 percent of all PINs in circulation. Birthdays make up another huge chunk, and they are particularly bad because they leak from social media profiles, public records, and casual conversation with people who do not need access to your accounts.
A truly random PIN solves both problems. It is statistically uniform across all possible digit combinations, meaning a thief guessing 1234 first has the same near-zero chance of success against your PIN as guessing 4729 or 8156. This generator gives you that uniform random output in one tap, without you having to invent digits that feel random but actually correlate with your life.
4-digit PINs have 10,000 possible combinations. That sounds like a lot, but it is the bare minimum for security. They are appropriate for physical cards (where the attacker only has three guesses before the card is blocked) but inadequate for systems with unlimited or many attempts.
6-digit PINs have one million combinations, which is the current default for iOS device unlock and many banking apps. This length is a good balance between memorability and security for most everyday uses.
8-digit PINs have 100 million combinations, which is comparable in strength to a moderate password and is appropriate for high-value accounts, password manager master codes, and encrypted vault access. We recommend 8 digits for anything where brute-force attacks are realistic.
A common worry with online PIN generators is that the server gets a copy of your PIN. That is a legitimate concern — a generator that logs PINs is a generator that has lost the plot. We deal with it by doing all the work in your browser. The JavaScript that runs this page generates the PIN locally using the browser's random number functions, displays it on your screen, and forgets it the moment you close the tab.
Our server never sees the PIN, our logs do not record it, and our analytics do not track it. You can verify this by opening your browser's developer tools and watching the network tab — no PIN-related traffic leaves your machine when you click Generate.
Even with a random generator, a few patterns are worth refusing if they happen to come up. Avoid PINs that match obvious dates in your life (year of birth, anniversary, phone area code). Avoid PINs visible to anyone who knows you. Avoid PINs that read the same forwards and backwards (palindromes like 1221 or 4554), since memorability and predictability often correlate.
If the generator hands you a PIN you do not like — say 1990 looks like a birth year — just regenerate. Each pull is independent, so getting a new one costs nothing and the next PIN has no relationship to the previous one.
The first few weeks with a new random PIN are the hardest. Until muscle memory kicks in, you will need a backup. The best option is a password manager — 1Password, Bitwarden, KeePass, and others all support PIN-style fields with the same encryption as your passwords. The second-best option is a piece of paper in a locked drawer or safe; obvious-looking stickers on a card are the worst option.
Once the PIN is in your fingers, the backup matters less for daily use, but keep it around for emergencies (a hardware fault that forces a re-entry, a long vacation where the PIN gets fuzzy in memory). Random PINs are slightly harder to recall than meaningful ones, but the security gain is real and worth the small friction.
