Measure your password strength, security, and estimated cracking time. Get detailed analysis and improvement suggestions.
Password entropy measures the randomness and unpredictability of a password in bits. Higher entropy means stronger security.
Entropy = log₂(Rᴸ) where R is character pool size and L is password length. We analyze character diversity and patterns.
A password with 50+ bits of entropy is considered secure against brute force attacks with current technology.
Based on entropy and attack speed, we estimate how long it would take to crack your password using various methods.
Use longer passwords, mix character types, avoid patterns, and consider passphrases for better security.
