### [How to Make Your AI Agent Enterprise-Ready: Enabling Enterprise-Managed Authorization for Client Apps in Auth0](https://yomu.fyi/post/how-to-make-your-ai-agent-enterprise-ready-enabling-enterprise-managed.md)

Auth0 is launching Early Access for Client App, or Requesting App, capabilities that support Cross App Access (XAA) for AI assistants, developer tools, and autonomous agents. In the Enterprise-Managed Authorization (EMA) model, an employee’s corporate SSO login can authorize access to external APIs or Model Context Protocol (MCP) servers through the IETF Identity Assertion Authorization Grant (ID-JAG) draft specification. Auth0’s Token Vault brokers the multi-hop exchange: it stores an upstream enterprise refresh token, retrieves a short-lived ID-JAG, exchanges it with the downstream Resource App, and returns a standard access token to the backend. Setup uses dashboard toggles and connection settings, followed by a standard /oauth/token federated exchange, while the API requires no XAA-specific changes. The release also describes audit logging, enterprise IdP policy control, OIN distribution, and caching downstream tokens because ID-JAG exchanges are rate-limited to 50% of the tier’s standard Auth API limit.


### [How to Implement a Secure Central Authentication Service in Six Steps](https://yomu.fyi/post/how-to-implement-a-secure-central-authentication-service-in-six-steps.md)

Shopify built Identity to reduce the overhead of managing separate staff accounts across multiple stores, where each Shop isolated user data and lacked single sign-on. The service uses OpenID Connect (OIDC) to centralize authentication while retaining destination-specific authorization, and it models legacy one-store accounts separately from Identity accounts that can access multiple destinations. Migration begins by synchronizing profile and security data, routing authentication through Identity, and prompting eligible users to verify email ownership, combine accounts, and provide required 2FA credentials. Single legacy accounts can be auto-upgraded without changing their UUID, while multi-account merges use a MergeSession and operations implemented with ActiveOperation; WebAuthn also supports physical security keys as a second factor. Finally, Shopify changed store signup and staff invitations to prevent new legacy accounts, reporting that more than 75% of active accounts had been upgraded or combined at the time of writing.
