FAQ
Where are the passwords stored?
Nowhere. They are only shown on the page and disappear when you close it.
What is entropy?
How unpredictable the password is, in bits. Each extra bit doubles the guessing effort.
Why no strong/weak label?
Such labels are misleading; the entropy number is more precise. Aim for at least 80 bits for important accounts.
