What is PwdHash2?
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.

Summary

Automatically generates per-site passwords if you prefix your password with @@ or press F2 beforehand. Prevents JavaScript from reading your password as it is typed. The same password will be generated at each subdomain: a.example.com matches b.example.com, a.example.co.uk matches b.example.co.uk, but a.co.uk and b.co.uk are different.

This is based on the Stanford PwdHash add-on, main changes to the original:

  1. Fixed defunct original version, caused by changes in Firefox 66.0.2 keypress event handling
  2. Highlight password field, if active
  3. Added option to change the hash algorithm from HMAC-MD5 to PBKDF2-SHA256 ( based on PwdHash-PoC )
  4. Added option to store a user-specified salt and iteration count.
  5. Added option to use legacy (Stanford PwdHash) mode by Shift-F2 or in the options
Hashed passwords can also be generated at https://gwuk.github.io/PwdHash2/
