CardSpace requires a minimum of
an eight-character password.
The ?¬?le is then saved and CardSpace returns to the Card
Chooser page. The ?¬?le can then be roamed to the desired machine.
When it is on the new machine, double-clicking the
backup ?¬?le will bring up CardSpace and prompt for the password
to decrypt the ?¬?le. The cards that are about to be restored
are shown for review, and when the user gives the okay by
clicking Restore, they get copied over to the local collection and
are ready to be used. Only cards with last modi?¬?ed times older
than the ones being installed are overwritten. The card-restore
capability of CardSpace is somewhat limited in this regard because
there is no option to pick which cards will be restored
and no indication of which cards will be overwritten.

Another interesting part of the backup and restore behavior is
that card history is not backed up. This means that after roaming
a card to a new computer, returning to a previously visited site
will trigger the ?¬?rst-time use experience and show the RP
Identi?¬?cation page.
