Password Strength Checker

What is Password Strength?

Password strength is a measure of how resistant a password is to being guessed or cracked. Strong passwords are essential for protecting accounts and sensitive information. Password strength depends on length, character variety, randomness, and avoidance of common patterns.

Our free Password Strength Checker evaluates passwords based on length, character variety (uppercase, lowercase, numbers, symbols), and common patterns. It provides real-time feedback and suggestions to help you create stronger, more secure passwords.

Why Check Password Strength?

Checking password strength is important for:

• Creating secure passwords for accounts
• Protecting sensitive information
• Preventing unauthorized access
• Meeting password policy requirements
• Improving overall security posture

Password Strength Factors

• Length: Longer passwords are stronger (12+ characters recommended)
• Character Variety: Mix uppercase, lowercase, numbers, and symbols
• Randomness: Avoid predictable patterns and sequences
• Uniqueness: Don't reuse passwords across accounts
• Avoid Common Patterns: Avoid "123", "abc", "password", etc.

Password Strength Levels

• Very Strong: 12+ characters, all character types, no common patterns
• Strong: 8+ characters, multiple character types
• Medium: 8+ characters, limited character variety
• Weak: Short length, limited character variety, common patterns

Best Practices

• Use Long Passwords: Aim for 12+ characters minimum
• Mix Character Types: Include uppercase, lowercase, numbers, symbols
• Avoid Personal Info: Don't use names, birthdays, or personal information
• Use Unique Passwords: Different password for each account
• Consider Password Managers: Use password managers for secure storage
• Enable 2FA: Use two-factor authentication when available

Common Password Mistakes

• Using short passwords (less than 8 characters)
• Using only one character type
• Using common words or patterns
• Reusing passwords across accounts
• Using personal information

FAQs

How long should my password be?

Passwords should be at least 12 characters long, with 16+ characters recommended for high-security accounts.

Should I use special characters?

Yes, including special characters increases password strength and makes passwords harder to crack.

Are password managers safe?

Reputable password managers use strong encryption and are generally safer than reusing weak passwords or writing them down.

Should I change my password regularly?

Regular password changes are less important than using strong, unique passwords. Focus on password strength over frequent changes.

What makes a password weak?

Short length, limited character variety, common words, predictable patterns, and personal information make passwords weak.
