When I generate an application-specific password to be used on google talk, Google states:No need to memorize this password. You should need to enter it only  once. Spaces don't matter.But this is confusing! I need to memorize this app-specific password. If I don't, how can I possibly log-in into my gtalk the next time? How is this password needed only once?
Google's 2-step verification - how to use application-specific password multiple times?
