 * Hi,
 * I tried enabling two-factor authentication, and I have a couple of questions.
 * First, is there a time limit on the authentication codes? With many websites 
   and services that use two-factor authentication, a generated code sent via text
   or email expires after a specific period of time (10 to 15 minutes seems typical).
   Is there an expiry time for these codes?
 * Second, I note that after entering the code and logging into the dashboard, there
   is an additional cookie: `itsec_interstitial_browser`. I presume that this cookie
   records the actual authentication, which raises two additional questions:
    a)
   Is this a session cookie or does it have some other normal duration? (This is
   hard for me to confirm because my browser is set up to delete all cookies at 
   the end of session, so unless I disable several settings, all cookies are functionally
   session cookies for me.) b) What information is included in the hashed value 
   this cookie contains?
 * Third, if I use email codes (not a mobile app) or generate backup authentication
   codes, are they generated by my server locally, or does the process involve any
   communication with iThemes or any other third-party service?
 * Thanks!

 * Hi,
 * It’s been months and I still haven’t gotten an answer to this. Does anyone have
   any idea?
