Meet shoppers in the newest digital storefront

Agentic commerce is an emerging transactional paradigm where autonomous AI agents discover, evaluate, and purchase products on behalf of human consumers directly within conversational interfaces. This architecture enables shoppers to delegate buying authority to AI assistants, allowing end-to-end purchases to occur more securely without the customer ever leaving the conversational application interface.

Payment credentials alone cannot authorize agentic checkout because they do not verify agent identity, transaction scope, or user consent duration. Without robust identity and access governance, a compromised payment credential exposes a merchant's inventory, pricing data, and private customer databases to automated exploitation and volume abuse.

Auth0 helps protect against automated agent threats by establishing verifiable agentic identities and enforcing human-in-the-loop verification. By verifying the specific human behind every agent action and enforcing short-lived, transaction-scoped permissions, Auth0 helps reduce automated impersonation, credential theft, and non-human bot abuse.

Auth0 handles AI agent authentication using the Agent-as-Principal pattern and helps secure on-behalf-of token exchange (RFC 8693). Using Cross-App Identity Metadata Discovery (CIMD), Auth0 registers agents and issues temporary, highly scoped tokens tied to specific transactions. This reduces long-lived credentials and enables the agent to operate strictly within delegated authority.

No, you can integrate Auth0's agent security layer directly on top of your existing identity provider (IdP) to secure agentic transactions. Auth0 connects seamlessly with your current authentication infrastructure, allowing you to deploy more secure agentic checkout capabilities and build trust without replacing your existing identity system.

Auth0 manages delegated user authority by issuing transaction-bound, scoped tokens. This helps ensure AI agents can make purchases only within the exact parameters authorized by the user, helping prevent any action beyond the specific delegated consent.

Yes, Auth0 supports human-in-the-loop approvals. Developers can configure Client-Initiated Backchannel Authentication (CIBA) or out-of-band push notifications to require user verification before an agent executes a high-value or sensitive transaction.

Auth0 helps secures agent access to third-party APIs by managing credentials in a secure token vault. This practice reduces hardcoded static API keys from agent source code, automatically rotates credentials, and reduces the risk of unauthorized access.

Traditional user authentication relies on human-centric methods like passwords and MFA for session management. AI agent authentication uses non-human, machine-first identities built on cryptographically verifiable principals to enable more secure, automated interactions.
