I had Microsoft authenticator logged in with my email id, that was providing third-party authentication for my twitter account, but then device got stolen and I have misplaced the backup code. When I logged in MS Authenticator app in my new device with same email id it didn't sync old codes. Now I am unable to log in to my twitter account without codes/backup code. How to recover old linked accounts ?
