Frequently Asked Questions

What makes a password strong?

A strong password is long (at least 12 characters), uses a mix of uppercase, lowercase, numbers, and symbols, and is completely random. Avoid dictionary words, personal information, and common patterns like "123456" or "password".

What is password entropy?

Entropy measures password randomness in bits. Higher entropy means more possible combinations, making the password harder to crack. A password with 60+ bits of entropy is considered strong, while 80+ bits is very strong.

Are the generated passwords truly random?

Yes! We use the browser's crypto.getRandomValues() API, which provides cryptographically secure random numbers. These passwords are truly random and unpredictable, not generated from simple mathematical formulas.

Is it safe to use this password generator?

Absolutely. All password generation happens entirely in your browser. Passwords are never sent to any server or stored anywhere. Once you close this page, the passwords are gone unless you've saved them yourself.
