Password generator.

Mint a strong random password — cryptographically secure, unbiased, with the character classes you want and a live entropy strength meter. Generated on your machine, never sent anywhere.

Length beats cleverness

The strength of a random password is just its entropy — how many equally-likely possibilities it was drawn from — and length raises that exponentially while a clever substitution barely moves it. A 20-character password from a full set is past 120 bits, which no amount of compute will brute-force. The two things that actually matter: use a cryptographic random source (not Math.random), and use a different password everywhere so one breach stays contained. Both are handled here.
