Background

Last Update: October 2025.

Important Note:

• If you are using the Wealth solution (Pricing Streaming Optimized Service or Pricing Streaming Service), the products currently support Authentication Version 1 only (As of May 2024). Please contact your LSEG representative to verify if you are using Wealth or RTO solution.
• The CIAM is targeted the RTO customers only, not the Wealth solution (Pricing Streaming Optimized Service or Pricing Streaming Service) and the RDP APIs HTTP services.

Refinitiv has been significantly investing in our authentication services to provide you with more resilient, reliable, and secure service to the products and solutions you use.

Security feature improvements made to the Customer Identity and Access Management (CIAM) capability will benefit a broad range of products, including Real-Time – Optimized.

Next Steps

The CIAM upgrade will be phased, running from Q2 2023. Customers will be expected to take action. The Refinitiv Implementation Management team will contact you to guide you through the required steps to ensure a swift and effective upgrade as part of your change management schedule.

This will include helping you create and entitle Version 2 Authentication IDs and plan your upgrade. You do not need to take any action until you have been contacted by this team.

Further Documentation

To help you prepare for these changes, our developer advocates have written a series of articles explaining the differences between V1 and V2 authentication, and guidance to developers on how to implement V2 authentication for each supported API type.

Please take time to read and understand the content relevant to your API type.
