Frequently asked questions
Are the generated passwords secure?
Yes, passwords are generated using the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. No passwords are ever sent to any server.
What makes a strong password?
A strong password is at least 12-16 characters long and includes a mix of uppercase, lowercase, numbers, and symbols. Avoid common words, patterns, and personal information.
How long should my password be?
At minimum 12 characters for personal accounts, 16+ for sensitive accounts. Longer passwords are exponentially harder to crack.
Should I use a password manager?
Absolutely. A password manager lets you use unique, strong passwords for every account without needing to remember them. Generate passwords here, then store them in your password manager.
What are ambiguous characters?
Ambiguous characters like O/0 (letter O and zero), l/1/I (lowercase L, one, capital i) look similar in many fonts and can cause confusion. The tool can exclude these.
