Ability to have a master key

[hwsamuel]

Password Hasher Plus allows for a master key that makes the password completely unique. This means that even if two people are using the same master phrase and website, they will get a completely different password. With Password Hasher for Firefox, this isn't possible

How exactly this supposed to work? We will have to enter master password each time we use passhash?

I think what you referring to is called "salt"
