Access to accounts saved in the authenticator

Question

Good morning, I have a problem that I thought never goes away. I thought I would be safe, however, I'm having worse problems, I saved several accounts in the Microsoft authenticator, Facebook, Instagram, Linkedin and others, I backed up and after formatting the cell phone the only account that came was Microsoft, now I can't access anything. Microsoft what I do now is don't suggest me to contact another company because the application belongs to you.
