NIST Password Security Standards
✅ Recommended Practices
- • Use passwords with at least 12 characters
- • Include uppercase, lowercase, numbers, and symbols
- • Use unique passwords for each account
- • Store passwords with a password manager
- • Enable two-factor authentication (2FA)
❌ Avoid These Practices
- • Using personal information (birthdays, names)
- • Using common passwords (123456, password)
- • Reusing passwords across multiple sites
- • Writing passwords on paper or documents
- • Sharing passwords through insecure channels
Technical Implementation & Security
🔐 Random Number Generation
Uses browser-native crypto.getRandomValues() API, a cryptographically secure pseudo-random number generator (CSPRNG) compliant with RFC 4086 standards.
📊 Strength Assessment
Evaluates based on password length, character type diversity, entropy calculations, and other dimensions, referencing OWASP password strength guidelines.
🛡️ Privacy Protection
All password generation and processing occurs entirely in your browser locally, with no data sent to servers, ensuring absolute password security.
Common Password Security Threats
🔨 Brute Force Attacks
Attackers use automated tools to try all possible password combinations. Strong passwords can extend cracking time from seconds to thousands of years.
📚 Dictionary Attacks
Attacks using common password lists. Avoid predictable passwords like common words, dates, and names.
🔄 Credential Stuffing
Using passwords leaked from other sites to attempt logins. Using unique passwords for each account effectively prevents such attacks.
