Question details
The user needs to locate specific Power Automate flows and Power Apps relying on the deprecating WS-Trust authentication protocol.

- Product
- Microsoft Power Platform
- Device & OS
- not provided
- Scenario
- An organization received a Microsoft deprecation notice regarding WS-Trust and needs to proactively find dependent connections to alert developers before they stop functioning.
- Observed behavior
- Administrators must audit the environment to discover which internal apps and flows still use the deprecated authentication method so they can be updated to modern standards.
Ensure you have Power Platform Administrator privileges or environment admin access to properly review all connections, custom connectors, and apps across your tenant.
Audit Power Platform Connections and Admin Center Tools
Use the Power Platform admin center and built-in inventory tools to track down connections relying on legacy authentication.
To properly mitigate the deprecation of WS-Trust, administrators must audit connections across all active environments. Depending on the size of your organization, this might require a combination of manual checks and automated inventory tools.
Navigate to the Power Platform Admin Center (admin.powerplatform.microsoft.com) and sign in with your administrator credentials.
Go to the 'Data' section and carefully review the 'Connections' and 'Custom Connectors' lists across your affected environments.
Inspect the authentication method for each active connector to determine if it relies on WS-Trust or legacy credentials rather than modern OAuth.
Once a legacy connection is identified, use the 'Connection References' tab to trace it back to the specific dependent Power Automate flows and Power Apps.
If your organization has installed the Center of Excellence (CoE) Starter Kit, open its Power BI inventory dashboards to quickly filter and isolate apps by their connection types.

Frequently Asked Questions
Why did I receive a Microsoft notice about WS-Trust?
Microsoft sends these notices to administrators when their tenant telemetry detects active Power Platform connections using WS-Trust, warning them to migrate to modern OAuth 2.0 authentication before the legacy protocol is disabled.
What happens if I do not update flows using WS-Trust?
Once the WS-Trust deprecation goes into full effect, any Power Automate flows or Power Apps attempting to authenticate using this protocol will fail, leading to broken business processes and data synchronization errors.
Can I use the CoE Starter Kit to find these connections?
Yes, the Center of Excellence (CoE) Starter Kit provides comprehensive inventory components. You can use its pre-built Power BI dashboards to filter and view all connections and clearly identify the specific apps or flows relying on them.
How do I securely seek help on community forums?
When posting on the Power Platform Community, ensure you share the exact deprecation notice text and connector types involved, but always redact your tenant ID, internal IP addresses, user credentials, and any proprietary business data.
