Recently I Reset my Phone. I installed authenticator app. I logged in but there is no restore account option. So by mistake I replaced new empty back with old backup. I lost all my authentication. After all of this I got to know that there is tiny recovery
option on app starting page before login. Now I manually emailing my document to recover my all account.
Recovery option must be in setting after login because it's not noticeable on app starting page with small text.
