Security Info
All passwords are generated client-side using crypto.getRandomValues() for cryptographic randomness. Nothing is sent to any server.
Entropy is calculated as length * log2(charset_size). A password with 80+ bits of entropy is considered very strong against brute force attacks.
Crack time estimates assume 10 billion guesses per second (high-end GPU cluster).
