Password vs passphrase

Two good options.

A random password packs maximum entropy into the fewest characters — perfect when a password manager remembers it for you.

A passphrase strings together random words from the 7,776-word EFF list. Each word adds 12.9 bits of entropy, so five words already means a ~64-bit secret you can actually type and remember.

True randomness

Every character is drawn from crypto.getRandomValues with rejection sampling — no modulo bias, no predictable seed.

Live entropy

The bit count updates as you adjust length and options, so you can see exactly how strong the result is.

Never transmitted

Generation happens on your device. Nothing is sent, stored, or logged.
