I can't authenticate the TFA app on my new phone unless I use an authentication code from the app on my old phone ... which is lost/ destroyed. There doesn't seem to be any other way to authenticate the app, for example by having a text or email sent to a pre-approved account. Thus, I now I can't get into my work account. This is a "secure" system in the sense that no external person can get into my work account, but leaves me with income insecurity as I can't get into it either.
