I have managed delete the authenticator account for my office 365 admin account, which runs on my iPhone.
When I try to login I get asked for the verification PIN, obviously I don't have that. When I chose a different method, it offers to send a PIN to the authenticator, but the authenticator just tells me the account is no longer available and may have to be added!!
How do I get the authenticator account back for this admin account?
Any advice very much appreciated.
