How it works
Choose settings that fit the account
Start with the account’s length and character rules. Each selected character type appears at least once. You can exclude look-alike characters (0O1Ilio) or punctuation that is awkward to type. Generate a new password after any change.
Use a new password for every account and save it in a password manager. The strength estimate checks common patterns, but it does not calculate exact entropy or guarantee safety. Short passwords remain risky even when they mix several character types.
Original JavaScript example
The downloadable MIT-licensed example uses rejection sampling and a cryptographic shuffle. It includes every default character type, rejects invalid lengths, and requires a secure browser context. The live demo uses the site’s shared browser engine.
import { generatePassword } from '/examples/password-generator.js';
const password = generatePassword(16);
