sms authentication

This sms authentication tag page currently features discussion of Microsoft Authenticator for personal Microsoft accounts. The highlighted change replaces multiple-choice push approvals with manual two-digit number entry, following Microsoft’s earlier use of number matching for work and school accounts. The coverage focuses on how an extra confirmation step can make sign-ins harder to approve accidentally and can help address prompt-spam attacks. It also places the change in a broader account-security context: improving authentication often means interrupting habitual approval behavior so users recognize and verify the request before completing it. The available material centers on Authenticator’s sign-in approval flow rather than SMS message delivery.
