About This Tool

This Random password generator tool creates strong, random passwords to help you maintain better online security. In an era of increasing cyber threats, using weak or repeated passwords is one of the most common security vulnerabilities. Our tool generates cryptographically strong passwords that are difficult to guess or brute-force.

How to Use

1. Set Password Length: Use the number input to choose your desired password length (8-64 characters)
2. Select Character Types: Check the boxes for the character sets you want to include:
   • Uppercase letters (A-Z)
   • Lowercase letters (a-z)
   • Numbers (0-9)
   • Symbols (!@#$% etc.)
3. Generate Password: Click the “Generate Secure Password” button
4. Copy Password: Click the copy icon to copy your new password to clipboard

Key Features

Security Notes

• Passwords are generated locally in your browser – never sent over the internet
• We recommend using passwords of at least 12 characters for important accounts
• For maximum security, combine with a password manager
• Always use unique passwords for different services

Technical Details

• Uses window.crypto for secure random number generation when available
• Falls back to Math.random() with additional shuffling for compatibility
• Implements proper password entropy calculations
• Follows OWASP password guidelines

Best Practices

1. Use different passwords for every account
2. Change passwords periodically (every 3-6 months)
3. Never share passwords via email or messaging
4. Consider using a password manager to store your passwords securely
