Your employer might use MS Authenticator but still let you do call or SMS 2FA. If you use a VOIP number, it won't be vulnerable to SIM card swapping attacks.
SMS auth is going away, it is not considered secure in the last few environments I have worked in
OP is looking for an alternative to MS Authenticator. If this works as an alternative temporarily, they may still consider it worth it.
Yes, SMS 2FA is usually not secure due being vulnerable to SIM card swapping attacks, that's why I explicitly recommended using a VOIP number, which would not be vulnerable to SIM card swapping attacks.
