Or switch to passphrase mode for words you can actually remember.
Randomness comes from the browser's cryptographic generator, on your device.
Nothing is stored or transmitted. Reload the page and it is gone.
The browser's crypto.getRandomValues, which is a cryptographically secure generator. It is not Math.random, which is predictable and must never be used for passwords.
Never. It is generated on your device and there is no network request involved - you can disconnect from the internet and this page still works.
Length beats complexity. A four or five word passphrase is both easier to remember and harder to crack than a short string of symbols, which is why the passphrase mode exists here.
16 characters or more for anything that matters, and never reuse one across sites. A password manager makes both of those painless.
Generate strong random passwords using the browser's own cryptographic randomness. Nothing is transmitted and nothing is stored - the page works with the network disconnected, which is the simplest possible proof that your password is not going anywhere. Length matters more than symbol soup: a four or five word passphrase is both easier to remember and harder to crack than a short string of punctuation, which is why passphrase mode is offered alongside character-based generation. Aim for at least 16 characters.
