I tried to log today (just by now), but I forgot my password, I even forgot if I had signed a simple account or using the click pass (i finally logged by trying the different signs up and the Google one worked for me).
I wander why HN don't implement a simple Passowrd recovery application, that let you recover your password using your username and send you the password reset to email.
Or what if I did forget my pass??
(I have not involvement with that site except as a user, but it's one of those things that I feel compelled to plug because it has made my life so much easier.)
