Suddenly Being Asked To Enter Login Details On Facebook Via Mobile

[countrykid]

For no apparrent reason I am suddenly being asked to enter user name and password to open up facebook (and one other site) using my mobile. Normally I can simply login to either, as the info has been "saved". Yesterday I received a amessage from a friend warning me about a possible scam re faceboook where you are being asked to respond to friend requests that have "appear" to come from people you are already friends with, and also asking that you "create a new account". Could the issue I am experiencing re needing to enter login details be connected in any way to this possible scam?

No connection. Is the relevant box (keep me signed in) still ticked? Have you cleared your cache- or has someone else who has used your laptop/tablet cleared the history?
