Test the resilience of your passwords against brute-force attacks.
Audit Your Security Credentials
Knowing how secure your password actually is can be eye-opening. Our Password Strength Checker uses advanced heuristics to estimate how long it would take for a computer to crack your password. It analyzes length, character diversity, and checks against common password databases. By getting a real-time score, you can identify if your current passwords are vulnerable and take steps to strengthen them. This is an essential tool for anyone auditing their personal security or for developers wanting to test the robustness of their user-authentication rules.
Common Mistakes
Using common words, sequential numbers (1234), or significant dates (birthdays) which are easily guessed by automated dictionary attacks.
FAQ
- What is a ‘Brute Force’ attack? A method where a computer tries every possible combination of characters until it finds the correct one.
- How do you calculate the strength? We use the ‘zxcvbn’ algorithm to estimate entropy and crack-time.
- Is my password sent to your server? No, the analysis is performed entirely within your browser for privacy.
- What is a ‘passphrase’? A sequence of random words which is often easier to remember but harder to crack.
- Does it check ‘Have I Been Pwned’? This version focuses on structural strength rather than historical breaches.
