How it works
The password is generated locally in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers — far less predictable than Math.random(). No generated password is ever sent to a server: everything happens on your device. The estimated strength is calculated from the password's entropy (length × log2 of the chosen character set size): the more possible characters and the longer the password, the higher the entropy and the harder it is to guess by brute force.
