A strong password is your first line of defence against unauthorised access. Short or predictable passwords can be cracked in seconds using dictionary attacks or brute-force methods. A randomly generated 16-character password with mixed character types would take trillions of years to crack by brute force with current hardware.
This generator uses crypto.getRandomValues(), the browser's cryptographically secure pseudo-random number generator (CSPRNG). This is the same randomness source used in TLS key generation — far more secure than Math.random().
Best practice: Generate a new password for every account, never reuse passwords, and store them in a password manager such as Bitwarden, 1Password, or KeePass rather than in a browser or plain text file.
