Why Passphrases?

High entropy from word combinations, not character complexity

Easier to remember and type than random character strings

Resistant to dictionary attacks when words are random

Recommended by NIST for human-generated passwords

All passphrases use crypto.getRandomValues() — generated entirely in your browser. Nothing is sent over the network.
