FAQ
How random are these PINs?
Each digit comes from crypto.getRandomValues(), your browser's cryptographically secure random number generator — the same source used for generating encryption keys, not the weaker Math.random().
Why is 10 digits the max for "no repeated digits"?
There are only 10 possible digits (0-9), so a PIN longer than 10 digits physically cannot avoid repeating at least one — the option is automatically limited to what's mathematically possible.
Can a PIN start with 0?
Yes — PINs are treated as digit strings, not numbers, so a PIN like "0472" is valid and keeps its leading zero.
Are the generated PINs stored or sent anywhere?
No — everything is generated and displayed locally in your browser. Nothing is saved after you leave the page, and nothing is ever transmitted.
