comment Necessity of Randomness of Salts?
@PaĆ­lo Thomas answers this in his comment with the two-password same salt problem. Perhaps I should have a 3) for that? Also, there is a practical consideration - what happens if you change user name for any reason? You'd need to recompute the hash, so you'd need the password to be input. That may or may not be acceptable to you.
