O365 - MFA - SMS deletion - question about alternatives

Hello gentlemen,

First of all, thank you for your reassuring feedback.

On the other hand, if today Microsoft does not remove the MFA by SMS, we can be sure that it will happen in the medium term. This is what happened for the obligation to switch to Modern authentication.

We can see here in the post of mr Alex Weinert the firm intention of Microsoft to rule out the use of SMS:

Also this MFA method change campaign on July 10, 2023 bears witness to this.

The problem is that switching methods for a large number of users can take time. So if we had an idea of the timeframe that would help us a lot.

Does anyone have any idea when Microsoft will completely cut this method? in 6 months ? 1 year ? 2 years ?

Have a nice day and thank you in advance
