Measures password randomness in bits.
Estimates how long an offline brute-force attack would take.
Analysis happens in your browser — nothing sent to a server.
Password entropy measures the unpredictability of a password in bits. Higher entropy means a stronger, harder-to-crack password.
Aim for 60+ bits of entropy. At 80+ bits, your password is effectively uncrackable by offline attacks.
No. Entropy is calculated entirely in your browser for total privacy.
