*SMS sign-in isn't available for office applications, such as Word, Excel, etc., when accessed directly on the web, but is available when accessed through the Office 365 web app

The above mentioned Microsoft apps support SMS sign-in is because they use the Microsoft Identity login (, which allows user to enter phone number and SMS code.

Unsupported Microsoft apps

Microsoft 365 desktop (Windows or Mac) apps and Microsoft 365 web apps (except MS One Note) that are accessed directly on the web don't support SMS sign-in. These apps use the Microsoft Office login (*) that requires a password to sign in. For the same reason, Microsoft Office mobile apps (except Microsoft Teams, Company Portal, and Microsoft Azure) don't support SMS sign-in.

Unsupported Microsoft apps Examples
