Random Generator

Leading zeros are kept. The Digits mode doesn't return a number, it returns a string of exactly the length you asked for — 000482 is a valid six-digit result and turns up just as often as 719305. That matters for PINs, ticket numbers and verification codes, where trimming the leading zero breaks the format.

Genuinely random, with no modulo bias. Values come from crypto.getRandomValues, the browser's cryptographic generator, and edge values that would make some outcomes more likely than others are thrown away rather than folded in. Each draw is independent of the last: it won't avoid repeating itself, and a number that hasn't come up yet doesn't become more likely.

Nothing leaves this device. There's no server and no shared seed — the history lives in this browser and disappears when you clear it. Good for raffles, sampling and throwaway codes; for real passwords use a password manager, which also stores them encrypted.
