Why are passphrases better than passwords?

Multi-word passphrases (like "Correct-Horse-Battery-Staple") provide high mathematical entropy against brute-force attacks while remaining much easier for humans to remember.

How are random words chosen?

Words are chosen using window.crypto.getRandomValues(), the web browser gold standard for cryptographic entropy.
