Spotfire: Deprecation of Identity Client Run Time Library (IDCRL) authentication and the Spotfire SharePoint Connector

Description

A query was raised regarding the impact of Microsoft's deprecation of Identity Client Run Time Library (IDCRL) authentication on the Spotfire SharePoint Connector. It was confirmed that Spotfire functionality does not rely on this legacy protocol but uses Microsoft Graph API, resulting in continued compatibility.

Solution

Spotfire's native SharePoint connector uses Microsoft Graph API for authentication and data retrieval.
- It does not utilize legacy IDCRL endpoints or third-party libraries.
- Compatibility with modern authentication standards is maintained.
- No changes are required concerning the IDCRL deprecation.

Per the below article, starting January 31, 2026, by default any requests containing this type of authentication calls are blocked. A workaround is available until May 1, 2026.
