// Generate a default password (16 chars, letters/numbers/symbols)
const password = generatePassword({ length: 16 });

It uses crypto.randomBytes in Node.js and window.crypto.getRandomValues in browsers to ensuring cryptographically secure generation in both environments.

Character Sets

• Lowercase: abcdefghijklmnopqrstuvwxyz
• Uppercase: ABCDEFGHIJKLMNOPQRSTUVWXYZ
• Numbers: 0123456789
• Symbols: !@#$%^&*()_+-=[]{}|;:,.<>?
• Ambiguous: il1Lo0O (excluded when using -x flag)

Security

This tool uses Node.js's built-in crypto.getRandomValues() function to ensure cryptographically secure random number generation. This makes the generated passwords suitable for security-sensitive applications.
