Frequently Asked Questions

Are the generated passwords stored anywhere? +

No. Passwords are generated using your browser's built-in cryptographic random number generator (crypto.getRandomValues) and never leave your device.

How strong is a 16-character password with all character types? +

A 16-character password using uppercase, lowercase, numbers, and symbols has approximately 95^16 ≈ 4.4 × 10^31 possible combinations — effectively impossible to brute force with current technology.

What makes a password secure? +

Length (16+ characters), variety (uppercase, lowercase, numbers, symbols), uniqueness (never reuse), and randomness (not based on words or patterns).

Why exclude similar characters like I, l, 1, O, 0? +

These characters look identical in many fonts and can cause confusion when copying passwords manually. Excluding them prevents copy errors without significantly reducing security.

How many characters should my password have? +

Security experts recommend at least 16 characters for most accounts. For critical accounts (banking, email), use 20+ characters. Our generator supports up to 128 characters.

संपूर्ण गाइड: Password Generator

Password Generator क्या है?

Password Generator cryptographically secure random passwords बनाता है जो brute-force attacks से protected होते हैं। NIST SP 800-63B guidelines के अनुसार, strong passwords में uppercase, lowercase, numbers, और special characters का mix होना चाहिए। Human-created passwords predictable patterns follow करते हैं जो attackers exploit करते हैं।

यह tool browser के crypto.getRandomValues() API use करता है — यह Math.random() से completely different है जो predictable होता है। Generated passwords कभी server पर store या transmit नहीं होते।

कैसे उपयोग करें

Length set करें slider से — minimum 16 characters recommended है।
Character types select करें: uppercase, lowercase, numbers, symbols।
Generate click करें नया secure password बनाने के लिए।
Strength indicator check करें — green = strong, red = weak।
Copy करें और password manager में save करें।

Pro Tips

16+ characters वाले passwords 12-character passwords से exponentially ज्यादा secure होते हैं।
हर account के लिए unique password use करें — password manager इसे easy बनाता है।
Special characters include करने से character space बढ़ती है और cracking time dramatically बढ़ता है।
