About Password & Passphrase Generator
Strong, unique passwords are the single most effective protection against account takeovers. This tool generates cryptographically random passwords and human-friendly passphrases entirely in your browser using window.crypto.
Nothing is sent to any server. Use a password manager to store the result.
Frequently asked questions
Are these passwords truly random?
Yes. They are generated with crypto.getRandomValues, the browser's cryptographically secure random number generator.
Should I use a passphrase or a password?
A 4-6 word passphrase from a large dictionary is easier to remember and as strong as a long random password. Use random passwords for sites where you rely on a password manager.
Where are these passwords stored?
Nowhere. Generation is local and ephemeral. Always copy the result into your password manager.
