This can&#x27;t be overstated.  Even if we got the general public to sort of understand PGP and PKI there is going to be a significant number of users that don&#x27;t understand the difference between a password and a password protected key.  The expectation is going to be that when they move to a new computer that their &quot;password still works&quot; and are going to be extremely angry when it doesn&#x27;t.
