Passwords are made with the browser's secure random source (crypto.getRandomValues). Nothing is stored, logged or sent. Copy a password only to a password manager or a place you trust.
How it works
Random numbers are drawn without bias, so every character in the chosen set is equally likely. The page guarantees at least one character from each selected set, then shuffles the result. Entropy is the length multiplied by the base-2 logarithm of the character pool size: the number of guesses an attacker needs grows exponentially with it.
