What makes a password strong?

Strong passwords typically include uppercase letters, lowercase letters, numbers, and special characters. They're also at least 12 characters long.

How does the strength indicator work?

The tool analyzes length, character variety, and common password patterns to calculate an estimated strength score.

Is my password stored?

No, your password is analyzed locally in your browser only. It's never sent to any server or stored anywhere.

Should I use common words?

No, avoid dictionary words and personal information. Random combinations of character types are much more secure.

How often should I change passwords?

Change passwords when compromised, but regularly changing strong passwords isn't as important as using unique, strong ones.

How It Works

Strength Calculation: Algorithm analyzes length, character variety, entropy, and complexity patterns
Character Analysis: Checks for uppercase, lowercase, numbers, and special characters
Common Password Detection: Identifies weak passwords from common password lists
Pattern Detection: Detects keyboard patterns and sequential characters
Time to Crack Estimation: Calculates approximate time needed to brute-force the password
Real-time Feedback: Updates strength analysis as you type
Privacy Protection: All analysis happens in your browser - no passwords sent to servers

Password Security Tips

Aim for at least 12-16 characters for maximum security
Use uppercase, lowercase, numbers, and special characters
Avoid keyboard patterns like "qwerty" or "12345"
Don't use personal information in passwords
Use different passwords for different services
Change passwords after security breaches
Enable two-factor authentication for critical accounts
