My mother had forgotten her old Facebook account log-in and had no clue as to whether she had one or not when she asked me (her son) to link her progress from one mobile device to another on her Candy Crush Soda Saga I created a new one for her. The problem however arose when she wanted to also sync her Pet Rescue Saga to her new device as well and thats when I found that her Pet Rescue Saga was linked to another account.Since her progress in the two games were linked to two different accounts I was wondering if anything could be done to sync her progress to one Facebook account so she can continue her progress in the games on her new device since I don't believe you can have two different Facebook accounts on one phone for apps.
P.S I found her old Facebook log-in but have no clue what to do with it
