FAQ
How secure are the generated passwords?
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. No password is ever sent to a server — everything runs in your browser.
What is a strong password?
A strong password is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using dictionary words, personal information, or common patterns.
Why should I exclude ambiguous characters?
Characters like 0/O, 1/l/I can be confused when reading passwords manually. Excluding them is useful if you need to type the password by hand.
How long should my password be?
For most accounts, 16 characters or more is recommended. For high-security applications, use 20+ characters. Longer passwords are exponentially harder to crack.
