    Why Use a Password Strength Checker?

    Hackers can guess weak passwords with automated tools in seconds. Reusing the same password across accounts increases the chance of data breaches.

    A Password Strength Checker shows if your password is strong enough to resist attacks. When you test it here, nothing is stored or tracked—your password never leaves your device.

    How the Password Strength Checker Works

    Our tool analyzes your password based on:

    • Length: Longer passwords are harder to crack.
    • Complexity: Mix uppercase, lowercase, numbers, and symbols.
    • Uniqueness: Avoid common words, patterns, or reused passwords.

    Why Strong Passwords Matter

    Weak passwords remain one of the most common causes of account hacks. By creating longer and more complex passwords, you reduce the chance of brute-force attacks. In addition, combining this checker with a secure password generator ensures even better protection.

    Best Practices for Safer Passwords

    To make the most of our Password Strength Checker, follow these tips:

    • Use at least 12–16 characters in every password.
    • Create unique passwords for each account you use.
    • Store your passwords in a trusted password manager.
    • Enable two-factor authentication (2FA) whenever it is available.
    • Update old passwords regularly, especially if you suspect a breach.

    Following these habits, together with using our tool, greatly increases your overall security.
