[Get started with Jentic One](/jentic-one#install)[View on GitHub](https://github.com/jentic/jentic-one) At a glance ## Jentic One vs Auth0 Token Vault, feature by feature A side-by-side look at where a self-hosted agent broker and a hosted token service differ. Feature Jentic One Auth0 Token Vault Primary job Govern the agent as the caller of any API. Identity and token custody: stores and exchanges OAuth tokens. Hosting model Self-hosted by default, or run for you with Jentic One Enterprise. Hosted in Auth0’s cloud. No self-host option. Where credentials live On your own instance. The agent never sees a key; the broker injects it at call time. Access and refresh tokens live in Auth0’s cloud. Governance Per-agent, per-operation rules. Writes denied by default. Gates by coarse OAuth scope, not per-operation rules. Audit Append-only log of every allowed and denied call, on your own instance. Logs token retrieval, not the agent’s API operations. Integrations 10,000+ APIs, plus any private or niche API via its OpenAPI spec. 30+ pre-built provider integrations plus custom OAuth 2.0 connections. Open source Yes, Apache-2.0 (OSI open source), including the broker that holds credentials. Proprietary, closed. A paid add-on to Auth0. Compliance ISO/IEC 27001:2022 certified, with a SOC 2® Type 1 report. SOC 2 Type 2, ISO 27001/27017/27018, PCI, HIPAA BAA, CSA STAR. The shared best practice ## Credentials never in the prompt Putting an API key in a prompt or tool call leaks it into logs, model providers, and anyone who can read the conversation. The right pattern is to store the credential outside the agent and inject it only at the moment of the call. Jentic One and Auth0 Token Vault both do this; they differ in where that happens and what else they govern. Head to head ## Jentic One vs Auth0 Token Vault, honestly These two sit at different layers and are closer to complementary than competing. Auth0 Token Vault is a mature, hosted identity service that stores and exchanges tokens. Jentic One is a self-hosted broker that governs what the agent does with them. Here is where each is genuinely stronger. ### Jentic One Self-hosted agent broker that governs the agent as the caller and audits what it did. Strengths - Self-hosted, so tokens, exchange and the audit log never leave your own infrastructure. - Governs the agent as a caller with per-agent, per-operation rules, with writes denied by default. - Audits what the agent actually did, with an append-only log of every allowed and denied call it made. - A directory of 10,000+ APIs, and you can import any private or niche API by its OpenAPI spec, not a fixed provider list. - ISO/IEC 27001:2022 certified, with a SOC 2® Type 1 report, both independently assessed by Prescient. - Open source under Apache-2.0, with no coupling to any identity vendor. Trade-offs - You run the instance yourself on the open-source tier, though Jentic One Enterprise can run it for you. - Public beta, and far newer than Auth0’s long-proven identity platform. - Not an enterprise IdP: no user login, SSO, or the deep OAuth/OIDC estate Auth0 brings. ### Auth0 Token Vault Hosted service that obtains, stores, refreshes and exchanges third-party OAuth tokens. Strengths - Deep, standards-based OAuth and OIDC maturity from a leading enterprise identity provider. - Fully managed token lifecycle that obtains, stores and auto-refreshes tokens, with zero infra to run. - Large compliance portfolio: SOC 2 Type 2, ISO 27001/27017/27018, PCI, HIPAA BAA, CSA STAR. - 30+ pre-built provider integrations plus custom OAuth 2.0 connections. - A natural fit if you already run Okta or Auth0, with SLA-backed vendor support. Trade-offs - Hosted only, so your access and refresh tokens live in Auth0’s cloud, with no self-host option. - An identity and token layer, not agent-call governance. It gates by coarse OAuth scope, not per-operation rules. - Audits token retrieval (which token was fetched, when), not what the agent did with the API. - Proprietary and closed, and a paid add-on (Auth for GenAI adds about 50% to the base price). Bottom line: Choose Auth0 Token Vault for managed, enterprise-grade token custody, especially if you already run Okta or Auth0. Choose Jentic One when you need the tokens to stay on your own infrastructure and to govern and audit exactly what the agent is allowed to do with them. Many teams will use both. ## Keep tokens on your own infrastructure Install Jentic One to inject credentials at call time and audit exactly what each agent does with them. [Get started with Jentic One](/jentic-one#install) Where they differ ## Self-hosted, with per-agent rules and audit Auth0 Token Vault is a hosted identity service that holds and refreshes tokens for you, and audits which token was handed out. Jentic One runs on your own infrastructure and governs the agent as the caller, adding per-agent, per-operation rules and an append-only audit of what the agent actually did on top of credential injection. - ### Credentials never leave your infrastructure Jentic One is self-hosted, so stored credentials and the audit log stay on your own instance rather than with a hosted provider. - ### Injected at execution, never in the prompt The broker injects the stored credential at call time. The agent receives only the result of an allowed call, so the key never enters the prompt or the model context. - ### Per-agent, per-operation rules Beyond storing credentials, Jentic One bounds each agent to the operations it needs. Writes are never allowed by default, and how granular this gets depends on the API. - ### Append-only audit on your instance Every allowed and denied call is logged in an append-only trail on your own instance, because the broker is the only path to any API. [See Jentic One](/jentic-one)[Browse the Jentic API Directory](/apis) FAQ ## Jentic One vs Auth0 Token Vault Store the credential outside the agent and inject it only at the moment of the call. In Jentic One you store a credential once and the broker injects it at execution time, so the agent receives only the result of an allowed call and the key never enters the prompt. They share the core idea that credentials never belong in the prompt. Auth0 Token Vault is a hosted service for storing and exchanging tokens. Jentic One is a self-hosted agent broker that injects credentials at execution and also enforces per-agent rules and an append-only audit log on your own instance. On your own instance. Jentic One is self-hosted, so credentials and audit logs never leave your infrastructure. Auth0 Token Vault, by contrast, is hosted, so your access and refresh tokens live in Auth0’s cloud. Token Vault audits token retrieval, meaning which agent fetched which provider’s token, and when. The agent then calls the third-party API directly, so Token Vault is not in that call path and does not log the operation itself. Jentic One is the only path to every API, so it keeps an append-only audit of every call the agent actually made, allowed or denied, on your own instance. Auth0 Token Vault is a hosted service from Auth0 (Okta) that obtains, stores, refreshes and exchanges a user’s third-party OAuth tokens so an app or agent can call external APIs on their behalf without handling the raw credentials. It is part of Auth0’s Auth for GenAI suite. It is a token-custody and identity layer; it does not govern which operations an agent may call or audit what the agent did with the API. No. Token Vault is a hosted service and your access and refresh tokens live in Auth0’s cloud; there is no self-host option. If you need credentials and the audit trail to stay on your own infrastructure, Jentic One is self-hosted and open source under Apache-2.0, with Jentic One Enterprise available if you want it run for you. Jentic One is an open-source (Apache-2.0), self-hosted alternative when the goal is governing an AI agent’s API calls. It injects stored credentials at call time so keys never enter the prompt, enforces per-agent and per-operation rules with writes denied by default, and keeps an append-only audit of every agent call on your own instance. Auth0 Token Vault remains the more mature choice for managed enterprise identity and token lifecycle at scale. They sit at different layers and can complement each other. Auth0 Token Vault excels at managed, enterprise-grade identity and token custody; Jentic One excels at self-hosted governance and audit of what an agent is allowed to do with those tokens. Many teams will use a hosted identity provider for user auth and Jentic One to broker and audit the agent’s API calls. ![]()![]() BOOK A DEMO ## Keep your keys out of the prompt Install Jentic One on your own infrastructure and inject credentials at execution, never in the prompt.
