Setting up Facebook on new Tablet

[king1]

The account in the name of another person which you can access?

Is this an account you set up?
Is this someone you know?
Is this the account you have been using on the old tablet/PC?

On the PC you can find the actual email/phone number of the account you're logged into, from
The account profile menu top right
Settings & Privacy
Settings
Personal Details on the left

The account was setup accidently when I followed the information from Facebook. I typed in what I thought was my password  and they came up with  "Rosalita Amis"
which I didn't notice and must have confirmed it. Old age is catching up I am afraid. I don't know this person. I searched on line for this person and it that account came does come up. I have uninstalled Facebook from the new tablet but I guess when I reinstall it I will be in the same position. Not sure how to proceed. Just to add that this account has nothing to do with the account I use on my old Tablet or on the PC. I just wanted to use the new tablet with the current account.

you can just sign out of the account if you are sure it is not yours -  must of been a heck of a good guess to get signed into someone else's account, and slightly worrying about the quality of Facebook security protocols...

Then sign in with your correct account.
