## Description

PwdHash2 is a Firefox add-on that automatically generates per-site passwords if you prefix your password with @@ or press F2 beforehand. It prevents JavaScript from reading your password as it is typed and generates the same password at each subdomain. PwdHash2 also offers optional more secure hashing algorithm and the ability to store a user-specified salt and iteration count.
