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.
