Policy CSP - ADMX_MSAPolicy

Tip

This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.

The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

./Device/Vendor/MSFT/Policy/Config/ADMX_MSAPolicy/MicrosoftAccount_DisableUserAuth

This setting controls whether users can provide Microsoft accounts for authentication for applications or services.

  • If this setting is enabled, all applications and services on the device are prevented from using Microsoft accounts for authentication.

This applies both to existing users of a device and new users who may be added. However, any application or service that has already authenticated a user won't be affected by enabling this setting until the authentication cache expires.

It's recommended to enable this setting before any user signs in to a device to prevent cached tokens from being present.

  • If this setting is disabled or not configured, applications and services can use Microsoft accounts for authentication.

By default, this setting is Disabled. This setting doesn't affect whether users can sign in to devices by using Microsoft accounts, or the ability for users to provide Microsoft accounts via the browser for authentication with web-based applications.
