What is PIN?
A PIN generator for numeric codes, with a strict mode that rejects runs like 1122 that people often guess.
How it works
Digits are drawn from crypto.getRandomValues; strict mode re-rolls until no adjacent repeated digits remain (capped attempts).

Predictable patterns
1234, 0000, and birth years are the first combinations attackers try — let the generator avoid them.
Frequently asked questions
Are short PINs secure?
A 4-digit PIN has only ~13 bits of entropy — fine for low-value unlock screens with rate limiting, but never use one for sensitive accounts.
