I've set up my Google account on Mavericks (System Preferences > Internet Accounts > Google) using an application specific password obtained from Google (because I use two factor authentication). Although I'm able to set it up successfully (for example I can open my emails in Apple Mail), it loses access after about ten or fifteen minutes, and it asks me for the password once again. How do I permanently configure the Google account on Mavericks using an application specific password? Thanks very much in advance to anybody who can answer this question for me. Cheers!
