// What is the Password Generator?
The Password Generator creates random passwords and passphrases using the Web Crypto API, the browser's cryptographically secure random source. You control length and which character classes are included, and the tool shows the resulting entropy in bits so you can see the security you are actually buying rather than guessing from a coloured bar. Entropy is dominated by length: adding characters increases the search space exponentially, while sprinkling symbols into a short password barely moves it. Because generation happens locally and nothing is transmitted or stored, the password exists only in your clipboard and your password manager. Generate one credential or a batch, with no rate limit and no account required.
