I facebook tried to log in to my facebook account via miniclient, but clicking on Facebook* didn't give anything.

I can log in to my old account with email, but I can't log in to my main account, which is linked to Facebook login due to a global server outage.

Can Facebook account be transferred to a regular gaming account or get *ternative way to log in through a Facebook account? because I'm wasting a lot of time I would like to get an answer as soon as possible
