About Password Strength Checking
What Makes a Strong Password?
- Length: At least 12 characters, ideally 16+
- Complexity: Mix of uppercase, lowercase, numbers, and symbols
- Uniqueness: Different from other passwords you use
- Randomness: Not based on personal information or common words
- No patterns: Avoid sequences like "123" or "abc"
Best Password Practices
- Use a password manager to generate and store passwords
- Enable two-factor authentication when available
- Change passwords periodically (every 3-6 months)
- Never share your passwords with others
- Use different passwords for different accounts
- Check for password breaches regularly
Frequently Asked Questions
How does the password strength checker work?
The tool analyzes your password based on multiple security criteria including length, character variety (uppercase, lowercase, numbers, symbols), patterns, and common vulnerabilities to provide a comprehensive strength score.
Is it safe to check my real password here?
Your password is processed entirely in your browser and never sent to our servers or stored anywhere. The analysis happens locally on your device, ensuring complete privacy and security.
What makes a password strong?
A strong password typically has 12+ characters, combines uppercase and lowercase letters, numbers, and special characters, avoids dictionary words, and doesn't use predictable patterns or personal information.
Why does my long password still show as weak?
Length alone doesn't guarantee strength. If your password uses predictable patterns, repeated characters, sequential letters/numbers, or common words, it may still be vulnerable to attacks despite being long.
What's the difference between a strong and very strong password?
Very strong passwords exceed minimum requirements with greater length (15+ characters), high entropy, unpredictable character combinations, and resistance to both brute force and dictionary attacks.
Should I use special characters in my password?
Yes, special characters (!@#$%^&*) significantly increase password complexity and make it much harder for attackers to crack through brute force or dictionary attacks.
How often should I check my password strength?
Check password strength whenever creating new passwords or updating existing ones. It's also good practice to periodically review and strengthen old passwords, especially for important accounts.
Can this tool detect if my password has been breached?
This tool focuses on password strength analysis. While it identifies common patterns that appear in breached password lists, it doesn't check against specific breach databases for privacy reasons.
What does the strength score mean?
The score ranges from 0-5: 0-1 (Very Weak), 2 (Weak), 3 (Fair), 4 (Strong), 5 (Very Strong). Higher scores indicate better resistance to various types of password attacks.
Why should I avoid dictionary words in passwords?
Dictionary words are vulnerable to dictionary attacks where hackers use common words and phrases to guess passwords. Even with numbers or symbols added, they remain more predictable than random combinations.
Is a passphrase better than a complex password?
Both can be strong if done correctly. Long passphrases (4+ random words) can be easier to remember and very secure, while complex passwords offer high entropy in shorter lengths. The tool evaluates both approaches.
What should I do if my password is rated as weak?
Follow the specific suggestions provided: increase length, add missing character types, remove patterns or repeated characters, and avoid common words. Aim for a 'Strong' or 'Very Strong' rating.
