Password Generator
Create strong random passwords and PINs — generated locally, never sent anywhere.
How to use the Password Generator
Choose a length and character set. Entropy is shown so you know how strong the password is.
Formula
Entropy (bits) = Length × log₂(Charset size)
Worked example
A 20-character password from 70 symbols has about 123 bits of entropy.
