16-character password generator
About this tool
With uppercase, lowercase, digits and symbols (about 94 possible characters), a random 16-character password has roughly 105 bits of entropy. That is strong enough for most accounts.
Some sites only allow certain characters; untick symbols if a site rejects your password.
FAQ
Is this password generator safe?
Yes. Passwords are created in your browser with the Web Crypto API (crypto.getRandomValues), a cryptographically secure random source. Nothing is sent over the network or stored.
How long should a password be?
At least 12–16 characters for normal accounts; 20+ for important accounts such as email and banking. Use a password manager so you do not need to remember them.
