Frequently Asked Questions
How does this password generator work?
Our generator uses the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. This is the same technology used by password managers like 1Password and LastPass.
What makes a password strong?
Password strength depends on length and character variety. A 16-character password with uppercase, lowercase, numbers, and symbols has about 105 bits of entropy — it would take billions of years to crack with current technology.
How long should my password be?
Minimum 12 characters for important accounts. 16+ characters is recommended. For maximum security, use 20+ characters. Every additional character multiplies the cracking difficulty exponentially.
Should I use a different password for every site?
Yes, absolutely! If one site gets hacked, attackers try stolen passwords on other sites. Use a unique password for every account, especially email, banking, and social media.
Is it safe to generate passwords in a browser?
Yes. Our tool runs entirely in your browser. Generated passwords are never transmitted, stored, or logged anywhere. Close the tab and the password exists only in your clipboard.
