There is planned work to address this scenario. We don’t feel that backup codes provide a good security option as they’re often misplaced. Also, it’s hard to have users print them out and have them when they’re needed. Instead, we are looking at a time-limited passcode that could be generated either by the user (just in time when it’s needed) or by an admin (for example a helpdesk agent). The organization admin would have control over when a user could generate these codes. The code can be used for a limited time, then it will no longer be valid.
Note – for areas with limited cellphone connectivity (or roaming charges), the code generated in the authenticator app will allow MFA login. The time-limited passcode is meant to stand in if the user temporarily forgot/lost their phone.

@Azure AD Team, it has been a year since the post above. When will "time-limited passcodes" options will be implemented?
