Password Strength Test: Check Password Security & Crack Time

The Real-Time Password Strength Test: How Long Would It Take to Crack?

In the fight against cybercrime, knowing the true strength of your password is the first line of defense. Simple, predictable passwords are the primary reason for compromised accounts. While a password might seem secure to you, a modern hacking program can test billions of combinations per second.

The Tooliz.online Password Strength Test uses advanced algorithms, like the widely respected zxcvbn library, to give you a genuine, real-time assessment of your password’s vulnerability. We don't just count characters; we analyze deep-seated flaws in your password structure.

What Our Password Strength Checker Evaluates:

• Estimated Crack Time: The most crucial metric. Our tool calculates the hypothetical time it would take a hacker using current technology to crack your password via a brute-force attack.
• Complexity & Entropy: We score the use of mixed character sets (uppercase, lowercase, numbers, symbols) and measure the **password entropy**—the true measure of randomness.
• Pattern Recognition: The checker intelligently identifies and penalizes common, easy-to-guess patterns, such as:
• Dictionary words and common names.
• Sequential numbers (e.g., *123456*).
• Keyboard sequences (e.g., *qwerty*).
• Easy substitutions (e.g., *P@$$w0rd*).
• Actionable Suggestions: If your password is weak, the tool provides instant tips on how to improve it, such as increasing length or introducing more special characters.

Your security is local and private. The strength test runs entirely in your browser. Your password is never transmitted over the network or stored on our servers. Use this tool to test your current passwords and make immediate, informed changes to secure your entire online life.
