Questions
How random are these passwords?
They use crypto.getRandomValues with rejection sampling, so every character is equally likely and unpredictable.
What does the bits number mean?
Entropy: length × log2(size of the character pool). Each extra bit doubles the guesses an attacker needs. 80 bits or more is very strong.
Is the password stored anywhere?
No. It exists only on this page until you close or refresh it.
