Β 
Strength: No Password
  • ⭘ At least 8 characters long
  • ⭘ Contains uppercase letter
  • ⭘ Contains lowercase letter
  • ⭘ Contains number
  • ⭘ Contains special character

Use our free password strength checker tool above to evaluate how strong and secure your password is.

This tool analyzes your password in real-time against multiple security criteria and provides instant feedback on its strength.

How the Password Strength Checker Works?

Our tool evaluates passwords based on five critical security factors:

  1. Length (minimum 8 characters)
  2. Uppercase letters (A-Z)
  3. Lowercase letters (a-z)
  4. Numbers (0-9)
  5. Special characters (!@#$%^&*(),.?":{}|<>)

The strength meter calculates a score based on how many of these criteria your password meets.

Each requirement contributes to the overall security score, with real-time visual feedback showing your password's strength level.

Understanding Password Strength Levels

The tool categorizes password strength into five levels:

  • Very Weak: Meets only one security requirement
  • Weak: Meets two security requirements
  • Moderate: Meets three security requirements
  • Strong: Meets four security requirements
  • Very Strong: Meets all five security requirements

Why Password Strength Matters?

Weak passwords are the primary entry point for cyber attacks.

Hackers can crack simple passwords in seconds using automated tools.

A strong password serves as your first line of defense against unauthorized access to your accounts.

Common Password Vulnerabilities

Several factors make passwords vulnerable to attacks:

  • Using personal information (birthdays, names)
  • Common word combinations
  • Keyboard patterns (qwerty, 123456)
  • Reusing passwords across multiple accounts
  • Short password length
  • Lack of character variety

Creating Strong Passwords: Best Practices

Follow these guidelines to create secure passwords:

  1. Use at least 12 characters: Using longer passwords significantly increases the time required to crack them. Each additional character exponentially increases the possible combinations.
  2. Mix Character Types: Combine uppercase letters, lowercase letters, numbers, and special characters. This diversity makes passwords harder to guess and more resistant to brute-force attacks.
  3. Avoid Personal Information: Don't use names, birthdays, or any information that others could find through social media or public records. Personal information is easily guessable.
  4. Use Unique Passwords: Create different passwords for each account. This prevents hackers from accessing multiple accounts if one password is compromised.
  5. Consider Using Passphrases: Long phrases with random words are both secure and memorable. Example: "correct-horse-battery-staple" is stronger than "P@ssw0rd123".

Password Manager Recommendations

Consider using a password manager to:

  • Generate random, strong passwords
  • Securely store all your passwords
  • Auto-fill passwords across devices
  • Monitor password security
  • Alert you about compromised passwords

Regular Password Security Maintenance

Implement these security practices:

  • Change passwords every 90 days
  • Enable two-factor authentication when available
  • Check for data breaches affecting your accounts
  • Avoid saving passwords in browsers
  • Never share passwords via email or text

Signs Your Password May Be Compromised

Watch for these warning signs:

  • Unexpected account logouts
  • Login attempts from unknown locations
  • Changed account settings
  • Unrecognized account activity
  • Password reset emails you didn't request

Additional Password Security Tips

Strengthen your password security further:

  • Use different security questions for each account
  • Implement biometric authentication when possible
  • Keep password recovery information up to date
  • Log out of accounts on shared devices
  • Review connected applications regularly

When to Change Your Password Immediately?

Change your passwords immediately if:

  • You notice suspicious account activity
  • A service announces a data breach
  • Your device is lost or stolen
  • You've shared the password
  • You've used public Wi-Fi without a VPN

Use this password strength checker regularly to ensure your passwords maintain high security standards.

Strong passwords provide essential protection for your digital identity and sensitive information.

Remember: Never enter actual passwords you use for your accounts into any online checker tool. Create similar test passwords instead to understand the strength patterns.
