Passwords are generated entirely in your browser using crypto.getRandomValues() — a cryptographically secure random number generator. Nothing is sent to our servers.
Why entropy matters
28 bits — cracked instantly
40 bits — cracked in minutes
60 bits — cracked in days
80 bits — years of compute
128 bits — quantum-resistant
Your current password has 129 bits of entropy. Aim for 80+ bits for secure passwords.
A strong password is only the start. Keep your connection private too — SecureFox encrypts your traffic with ML-KEM-768 hybrid PQC.
