PIN Generator
PIN Generator creates cryptographically secure random numeric PINs of any length from 3 to 12 digits, using the Web Crypto API.
An optional filter avoids obviously weak PINs like "1111" or "1234" by rejecting repeating and sequential digit patterns and re-rolling.
How to Use the PIN Generator
- Open the PIN Generator tool.
- Set your desired PIN length.
- Set how many PINs you want to generate.
- Optionally enable "Avoid repeating/sequential digits".
- Click Generate and copy the PIN(s) you want to use.
Frequently Asked Questions
Is this more secure than picking my own PIN?
Generally yes -- people tend to pick memorable but predictable PINs (birthdays, repeated digits). A randomly generated PIN avoids that predictability.
What does "avoid sequential digits" filter out?
It rejects PINs where every digit is the same (like 0000) or where the digits count straight up or down (like 1234 or 4321), then generates a new one.
Are the generated PINs stored anywhere?
No, they exist only in your browser tab and disappear when you leave or refresh the page.
