Frequently Asked Questions
How secure are the generated passwords?
Passwords are generated using crypto.getRandomValues(), the browser's cryptographically secure random number generator. No passwords are stored or transmitted.
What does the strength indicator measure?
The strength indicator is based on password entropy, calculated from the length and the size of the character pool. Higher entropy means a harder-to-crack password.
What are ambiguous characters?
Ambiguous characters (0, O, l, 1, I) look similar in many fonts and can cause confusion. Excluding them makes passwords easier to read and type manually.
