Check password entropy and crack time
The Password Strength Tester analyzes your password to determine how secure it is against modern hacking techniques like brute-force or dictionary attacks. It calculates an entropy score based on length, character variety (uppercase, lowercase, numbers, symbols), and meaningful patterns. The tool provides an estimated "crack time" and gives actionable feedback on how to improve your password's resilience. All analysis happens locally in your browser—your password is never sent over the internet or stored anywhere.
