FAQ

Very secure. They use the Web Crypto API (crypto.getRandomValues), the same source of randomness used for TLS encryption.
Based on 10 billion guesses per second (a generous estimate for modern hardware). Actual crack time depends on the attacker's resources.
Entropy (in bits) measures password unpredictability. Higher is better. 80+ bits is strong, 128+ bits is extremely strong.
