faq
What is the entropy score?
It measures the randomness of a password; higher entropy scales the difficulty of hacking exponentially.
Is my password sent to a server?
No, all logic runs locally in your browser to ensure your password stays private and secure.
What is a safe score?
Generally, an entropy score above 80 bits is considered highly secure against modern attacks.
