Password Strength Checker

How Password Strength is Measured

Password strength is evaluated using multiple factors including length, character variety, entropy, and resistance to common attack methods. Our analyzer uses advanced algorithms to provide comprehensive security assessment.

Key Security Factors

Understanding what makes a password strong helps you create better security practices:

• Length: Longer passwords exponentially increase security
• Character Variety: Mix of uppercase, lowercase, numbers, and symbols
• Randomness: Avoid patterns, sequences, and dictionary words
• Uniqueness: Never reuse passwords across different accounts
• Unpredictability: Avoid personal information and common substitutions

Understanding Entropy

Entropy measures the randomness and unpredictability of your password. Higher entropy means more possible combinations and stronger security:

• Low (< 40 bits): Weak security, easily cracked
• Medium (40-60 bits): Fair security for basic accounts
• High (60-80 bits): Good security for important accounts
• Very High (80+ bits): Excellent security for sensitive data

Common Attack Methods

Passwords can be compromised through various attack methods:

• Brute Force: Systematically trying all possible combinations
• Dictionary Attacks: Using common words and phrases
• Hybrid Attacks: Dictionary words with number/symbol variations
• Social Engineering: Using personal information
• Data Breaches: Leaked password databases

Improving Password Security

Follow these best practices to enhance your password security:

• Use a unique password for every account
• Enable two-factor authentication when available
• Consider using a reputable password manager
• Regularly update passwords for sensitive accounts
• Avoid using personal information in passwords
• Be cautious of phishing attempts and suspicious links
