Microsoft tells users to stop phone-based multifactor authentication

San Francisco: Microsoft is asking its users to avoid telephone-based multi-factor authentication (MFA) solutions like one-time codes sent via SMS and voice calls and instead replace them with newer MFA technologies, like app-based authenticators and security keys.

According to ZDNet, Alex Weinert, Director of Identity Security at Microsoft has urged users to embrace and enable MFA for their online accounts.

Weinert said that if users have to choose between multiple MFA solutions, they should stay away from telephone-based MFA.
