Frequently Asked Questions
Is this password generator secure?+
Yes. All passwords are generated locally on your device using the browser's native crypto API. We never store or transmit your passwords.
What makes a password strong?+
A strong password is long (at least 12-16 characters) and uses a mix of uppercase, lowercase, numbers, and symbols to maximize entropy.
What is password entropy?+
Entropy measures how unpredictable a password is. A higher pool of available characters (e.g., adding symbols) and a longer length exponentially increases the time it would take to crack.
