Hauríeu d' autenticar una persona el primer cop que parleu amb ella usant l' OTR. Si no ho feu, no podeu estar realment segur que algú altre no l' estigui suplantant o intentant escoltar la vostra conversa. En canvi, un cop hàgiu autenticat el vostre amic un cop, ja no ho haureu de tornar a fer. L' OTR farà automàticament l' autenticació per a totes les futures converses amb aquest amic.
You should authenticate a buddy the very first time that you talk to them using OTR. If you do n't, then you cannot really be sure that someone else is n't impersonating them or trying to listen in on your conversation. However, once you've authenticated your buddy once, you do n't have to do it again. OTR will automatically do the authentication for all of your future conversations with that buddy.
