About this tool
Strong passwords should be long (14+ characters) and mix uppercase, lowercase, digits and symbols. This generator uses your browser's cryptographic random number generator (crypto.getRandomValues), which is far stronger than Math.random(). Generate, check the entropy estimate, and copy — the password never leaves your device.
