Daily.Entra.News6 changes were tracked across 4 Microsoft Entra products. The leading updates include (Update)Action Required: Trust DigiCert Global Root G2 Certificate Authority for using Entra services by January 7, 2026; External authentication methods (EAM) – Public preview update; Manage Agents in end user experience (Preview).
By January 7, 2026, Microsoft Entra will switch from DigiCert Global Root G1 to G2 certificates. Organizations must trust the DigiCert G2 root CA to avoid authentication failures with Entra services. Remove any pinning to G1 and update trust settings to prevent service disruption.
External Authentication Methods (EAM) Public Preview will enforce registration starting December 8, 2025. Existing users are pre-registered; new users after December 2, 2025, must complete in-line setup. Admins can register users. Organizations should prepare by communicating changes and reviewing configurations.
Historically, AI agents would rely upon tools to interact with various applications and systems, and each of those tools would have their own identities in those applications and systems. Some of those tools would use service principals to authenticate to Microsoft services via Microsoft Graph or Microsoft Azure APIs. [Microsoft Entra Agent ID](../agent-id/identity-platform/what-is-agent-id.md) introduces support for identities for the agents themselves, with four new types of object: agent identity blueprint, agent identity blueprint principal, agent identity, and agent user. Through the [agent identity blueprint](../agent-id/identity-platform/agent-blueprint.md), the agent can create one or more agent identities, and optionally an agent user for each agent identity. Each agent identity and agent user can have distinct access rights.
The Manage Agents feature in Microsoft Entra lets you view, and control, [agent identities you own or sponsor](agent-owners-sponsors-managers.md). [Agents identities](what-is-agent-id.md) are special identities, such as bots or automated processes, that act on behalf of users or teams. With the manage agents feature, you can easily see which agents you’re responsible for, review their details, and take action to enable, disable, or request access for them.
The first step to perform an access review is to find and open the access review.
