Frequently Asked Questions
How are passwords generated?
Passwords are generated using cryptographically secure random number generation in your browser's crypto API. Each character is randomly selected from your chosen character set, ensuring true randomness and security.
Are my passwords stored anywhere?
No. All password generation happens locally in your browser. Passwords are never sent to our servers and are never stored. Once you leave the page, generated passwords exist only where you've chosen to save them.
What password length should I use?
We recommend 12-16 characters for most online accounts. Our default of 16 characters provides excellent security against brute-force attacks. For highly sensitive accounts (email, banking), consider 20+ characters.
What are ambiguous characters?
Ambiguous characters are those that look similar to each other (like lowercase 'l' and number '1', or uppercase 'O' and number '0'). Excluding them helps prevent typing errors and confusion when manually entering passwords.
