Good password hygiene comes down to a few habits: use strong, unique passwords, know when one is actually weak instead of just assuming, and understand two-factor authentication well enough to test it properly. Every tool here runs entirely client-side with no network calls — nothing you generate or type is ever sent anywhere, even temporarily.
It's a genuine technical guarantee, not just a claim — these pages make no network requests at all, so nothing you type or generate could be transmitted even if it wanted to.
The Password Generator creates a maximally random string of characters — best when it'll be saved in a password manager. The Passphrase Generator creates several unrelated real words strung together — easier to remember and type correctly, a better fit for something like a password manager's own master password.
It's built and framed as a developer/testing utility — a dedicated authenticator app or hardware security key is the safer long-term home for a real account's 2FA secret.
