I just saw a thread about accessing of phones by couples,so i decided to share this,is it necessary for married couples or those dating each other to have each others password on social networks?Won't it be like monitoring each other.At times some do log into chat sites with their partners password and start chating with their partners friends,it looks absurd to me,don't know about you.....

It is absurd, and I don't think it's necessary at all. Anyone who trusts his or her partner or spouse won't need the other's password. Demanding for it is childish in my opinion.
