Debian 8.4 now comes up with logon screen

I have been successfully using this release for awhile now by interacting it through an 7" LCD. All of a sudden it now does not automatically displays my Debian Desktop but has a logon screen.

I cannot logon to it with user/password of debian/temppwd but only with root/

How can I change this back so it always goes directly to the debian desktop without having to login first?

Actually it is on version 8.3 that I am having this issue with.
