How long should passwords be?
Security experts recommend at least 12-16 characters for strong passwords. This tool defaults to 16 characters, which provides excellent protection. Longer passwords (20+ characters) are even better, but consider usability. The password strength indicator will show you how strong your generated passwords are.
Do I need special characters?
Special characters (!@#$%^&*) add complexity and significantly increase entropy. Many systems require them. This tool includes them by default, but you can disable them if a service doesn't support special characters. Generally, keep them enabled for maximum security.
Should I use a password manager?
Absolutely. Password managers securely store and auto-fill strong passwords, so you don't have to remember them. This is the best practice for managing multiple accounts. Use a tool like this generator to create strong passwords, then let your password manager store them.
What is password entropy?
Entropy measures randomness and password strength. More character types (uppercase, lowercase, numbers, symbols) and longer passwords increase entropy. For example, a 12-character password with all four character types has much higher entropy than a 12-character lowercase-only password, making it harder to crack.
