About this PIN generator
A personal identification number protects bank cards, phones, door locks, voicemail, and app logins. People tend to pick memorable codes, and studies of leaked PINs show that 1234, 1111, 0000, and birth years make up a large share of all four-digit choices, so attackers try them first. This generator picks every digit with your browser’s cryptographically secure random generator and, if you wish, rejects codes with all-equal digits or straight runs such as 1234 or 9876. You can leave out digits, require every digit to be different, and group long codes for easier reading. The strength line shows how many guesses a PIN of this kind is worth, measured in bits.
How to generate a PIN
- Set the length. Choose 4 digits for most cards, 6 for phones and apps, or more for door codes and account numbers.
- Add rules. Avoid patterns, use each digit once, leave out digits your keypad lacks, or group long PINs.
- Press Generate PINs. Click any PIN to copy it, or copy and download the whole list.
Frequently asked questions
How many 4-digit PINs are there?
There are 10,000, from 0000 to 9999. A 6-digit PIN has 1,000,000 possibilities, which is why phones now suggest six digits.
Which PINs should I avoid?
Avoid repeated digits like 1111, sequences like 1234, birth years such as 1990, and dates. These are the first codes anyone guessing will try.
Is a random PIN safe to use?
Yes. Each digit comes from a cryptographically secure source in your browser, and nothing is sent to a server or stored.
Why avoid patterns if it reduces the choices?
Removing patterns drops only a small number of codes but ensures you never get one that people commonly guess, which matters more for short PINs.
What does bits of randomness mean?
It is the number of yes-or-no guesses that equal one PIN. Each extra bit doubles the guesses needed; a 4-digit PIN has about 13.3 bits, a 6-digit one about 19.9.
