Strong passwords, generated privately
Everything here runs in your browser using your device's cryptographically secure random number
generator (crypto.getRandomValues), not
a predictable one. Nothing you generate is sent anywhere, logged, or stored, so refreshing the page
loses it. This is a generator, not a vault: paste what you make straight into the
account, and use a dedicated password manager to remember it.
Passwords vs passphrases
A random password packs the most strength into the fewest characters, which suits fields with length limits. A passphrase of several random words (drawn from the public EFF list of 7,776 words) is far easier to type and remember for the same strength, which is handy for things you log into by hand. The strength figure is the entropy in bits: more is better, and roughly 70 bits or more is solid for important accounts.
