Explore Cross App Access end-to-end with xaa.dev, a free, open playground that lets you test the XAA protocol without any local setup or infrastructure.

The Okta Developer Blog serves as a resource for developers seeking insights into modern identity and access management (IAM) solutions. Through a diverse range of articles, tutorials, and best practices, developers can deepen their understanding of OAuth, OpenID Connect, and other authentication protocols integrated with Okta's identity platform. Additionally, the blog covers topics such as multi-factor authentication (MFA), user management, and secure API authentication, empowering developers to implement robust identity solutions in their applications.

Cross App Access (XAA) solves the challenge of letting AI agents and applications securely access enterprise resources on behalf of users without consent prompts or credential exposure. Built on the emerging IETF Identity Assertion JWT Authorization Grant specification, XAA shifts access control from end users to the enterprise identity layer using cryptographically signed ID-JAG tokens. The new xaa.dev playground provides a free, zero-setup testing environment where developers can explore the complete XAA flow across all components: requesting apps, resource apps, identity providers, and MCP servers. The playground eliminates the complexity of local infrastructure setup, allowing developers to understand token exchanges, inspect protocol flows, and test their own applications against working XAA implementations in under 60 seconds.
