sms sign-in

The sms sign-in tag covers discussions about Microsoft's plan to phase out SMS-based authentication for personal Microsoft accounts by 2026. The shift replaces text-message sign-in and account recovery with passkeys, authenticator apps, and verified secondary email addresses. This change affects the Windows account ecosystem and is driven by security concerns, though the transition may expose limitations in passwordless sign-in infrastructure. Topics include the migration away from SMS codes, the role of authenticator apps, and the broader move toward more secure authentication methods.
