Azure MFA (but dont always have a phone)?
We are working on deploying Azure MFA (cloud only).
An interesting scenario has come up with users that don't have mobile phones. While the scenario rare, what is a user to do if (1) they don'...

Two things - it doesn't have to a be a mobile phone - it could be any predefined phone such as a landline.
I have customers where the 1st MFA phone is a users mobile, but the backup is the "Secretary" administrative assistant person.
The protocol is if UserX call the AA and gives a heads up that he (the AA ) will be getting a phone call from MSFT auth. The AA puts UserX on hold and checks with UserX boss or userX calendar to confirm that offsite and also tries to call user X to confirm no answer.
Then the AA tells UserX to go ahead and trigger Auth.
Cumbersome - but provides the some level of identification anti-spoofing verification.
The business could also look into providing a non-smart phone with a text only plan (aka pager).
There is also this for the "I forgot my phone at home" : https://docs.microsoft.com/en-us/azure/multi-factor-authentication/multi-factor-authentication-whats-next#one-time-bypass

The bypass is server-only, read the description:
SpoilerAllow a user to authenticate without performing two-step verification for a limited time. The bypass goes into effect immediately, and expires after the specified number of seconds. This feature only applies to MFA Server deployment.- Dustin_HalvorsonApr 13, 2018Steel Contributor
Why is bypass only for on-prem only? It seems like the cloud MFA admin capabilities are very limited.

That's a question you should be asking Microsoft :)
