Just looked - Microsoft Authenticator doesn't appear to work. I might be able to get off of it but it will take some prep. My banks are supported so that's good.

Thanks for the link, I'll take a look. I might just move it to a secondary device first.
My uni does it and I've had use the only alternative option, cell call, and rigged Tasker to automatically answered and play the needed tone so I don't need to carry it with me.
