Connect AI agents to apps and APIs

The Auth0 Token Vault is a security feature that manages and protects third-party API tokens used by AI agents on behalf of users. It stores, retrieves, and automatically refreshes OAuth 2.0 tokens for external services (such as Google, GitHub, Salesforce, etc.), verifying that sensitive credentials are not exposed to AI agents or client-side code. This significantly reduces the risk of token theft and unauthorized API access in modern agentic architectures.

AI agents often need to perform actions across multiple third-party services on a user's behalf, such as reading emails, creating calendar events, or updating CRM records. Without Token Vault, developers would need to manage token storage, refresh logic, and secure access themselves, risking token leakage to the agent or insecure storage. Token Vault solves this by providing a dedicated, secure layer that manages the full token lifecycle, allowing agents to request API access at runtime without possessing or seeing raw user credentials.

AI agent applications direct the user to Auth0 to authenticate with a third-party service (e.g., Google) via a standard OAuth 2.0 consent flow. Once the user grants consent, Auth0 stores the resulting refresh token in Token Vault. When an AI agent or application needs to call that third-party API on the user's behalf, it requests a valid access token from Token Vault using a more secure, scoped API call. Token Vault uses the refresh token to request a short-lived access token and returns it to the agent to make the API call. The user only authenticates once, and Token Vault manages ongoing access.

Integrations are pre-configured connections to third-party services (such as Google, GitHub, Slack, Salesforce, and LinkedIn) that define how Auth0 authenticates with those services on behalf of a user. Each integration specifies the OAuth 2.0 provider details, required scopes, and credentials. Auth0 provides a catalog of supported integrations that can be set up through the Auth0 dashboard, making it straightforward to connect new external services to your application or agent without writing custom OAuth plumbing.

Auth0 Token Vault helps secure AI agents by acting as a 'broker' for API calls. Instead of the AI agent holding a long-lived secret, it requests a short-lived token from the vault to perform specific tasks. This limits the blast radius if an agent is compromised and provides a clear audit trail of which agent accessed which external service and when.

The Auth0 Token Vault provides comprehensive logging and auditing for every token retrieval event. Security teams can monitor which applications or agents are calling specific APIs, identifying unusual patterns that might indicate a breach or misuse. This visibility is essential for maintaining compliance in highly regulated AI and data-driven environments.

Auth0 Token Vault is designed to be highly flexible, supporting any third-party service that uses standard OAuth 2.0 authentication flows. Auth0 provides a growing catalog of pre-built integrations for popular services and allows configuring custom integrations for other OAuth 2.0-compatible providers. This allows developers to secure a wide range of integrations under a single, unified security and identity framework managed by Auth0.
