Let's say I'd like to add a small amount of extra security to my SSH login process.

Let's say I decide the way I want to do this is by requiring BOTH a password and an RSA key.  There appear to be patches, or procedures, that allow me to do this.  So to log in, I would be required to enter a normal unix password, but I would ALSO be required to hold a proper RSA public key.

My question is this:

In terms of security (and correctness ?) what's the difference between this (unix password + SSH RSA key) and simply generating my RSA key *with* a password ?  Both ways require me to "have something" and "know something", but they are obviously different, technically.

Comments on the difference, and relative security of the two methods ?
