Microsoft announces public preview of certificate based authentication for iOS and Android Office apps

Azure AD

Microsoft Identity team yesterday announced the public preview for certificate based authentication for iOS and Android for Office 365. Even though this is the first public preview, Microsoft mentioned that the solution is already relatively mature and being used by some of their largest enterprise customers.

This new feature lights up following two scenarios:

  1. In federated Azure AD domains, Office applications on iOS and Android can perform certificate-based authentication against the federation server. The chart below outlines the support for certificate based authentication across Office applications:

    OneDrive Supported Supported
    Outlook Coming soon Supported
    Skype for Business Coming soon Supported
  2. Supported Exchange ActiveSync mobile apps in iOS and Android can now do certificate-based authentication to Exchange Online, for both managed and federated Azure AD domains.
