Cross App Access for Resource Applications enters Open Early Access

We're excited to announce that Cross App Access (XAA) for Resource Applications is now in Open Early Access. You can use this feature in production today at no additional cost through Auth0 Enterprise Connections, available to Enterprise, B2B Pro, and B2B Essential customers, or test it during the trial period on Free tenants.

Cross App Access (XAA) is a new open standard for passing authorization across domains, built for the emerging Enterprise AI landscape, enabling seamless agent-to-app and app-to-app connections. Connecting AI Agents and Third-Party Apps in an enterprise introduces two key challenges: poor IT visibility into data sharing, and repetitive user consent flows. XAA solves this by centralizing IT control over these connections, eliminating consent fatigue while improving governance and visibility into data sharing.

This release is for the Resource App side: any Auth0 customer looking to expose their MCP servers and APIs to AI Agents and other enterprise applications. No code changes are needed: simply configure the feature on your Auth0 tenant to instantly support central policy enforcement and a seamless user experience. XAA supports both SAML and OIDC enterprise IdPs, with specific support for Okta.
