About passphrases
A passphrase is a password made of words. Six random words from a diceware list give about 77 bits of strength. A person can remember six words. A person cannot remember a random string with the same strength.
The tool picks each word with crypto.getRandomValues from a list of 7776 words. Each word adds about 12.9 bits. Use six words for a login. Use eight words or more for a disk encryption key or for the master password of a password manager.
Set the word count, the separator, and the capitals. A capital letter and a separator add little strength. The word count adds strength. Do not change a word after generation, because a change that a person makes is not random.
Every passphrase is made in your browser. Nothing is sent to a server. Use the Password Benchmark tool to see how long an attack on the result takes.
