I saw your same message in another thread.
That's why I thought maybe it was Miranda that caused my problem. What I was asking was if it's possible to add the ability in miranda to use a mobile phone number to log in to messenger? I wasn't aware that was even possible till a friend told me recently.
Miranda is only able to use an email address and password that are the same as your FB account. The official Messenger for Facebook and Pidgin have the ability to use a mobile phone number to log in without needing a facebook web account at all.
