Should I use a real sentence?

No — memorable sentences are far less random. Use randomly generated words.

A five-word passphrase from a 1,600-word list has over 50 bits of entropy — far more than most people’s memorable passwords.

Entropy = number of words × log₂(size of the word list)

Input

5 words

Result

e.g. quiet-tiger-harbour-lantern-42
