Hey DEV Community! π
If you're building AI agents right now (and honestly, who isn't?), you've probably hit the auth problem. You know the one - where the quickest path to getting your agent working is to just hardcode some API keys and move on. It works great... until you need to actually ship to production.
Today, we're excited to share that Auth0 for AI Agents is now generally available, and it's designed to solve exactly this problem.
The Problem with Hardcoded Credentials
Let's be real: when you're prototyping an AI agent with LangChain or LlamaIndex, hardcoded credentials are the path of least resistance. Your agent needs to access Slack, GitHub, Google Calendar, or your own APIs, and frameworks make it easy to just plug in those keys.
But production is a different story:
- What happens when your agent needs to act on behalf of different users with different permissions?
- How do you handle token refreshing across 30+ different apps?
- How do you let users approve critical actions (like making purchases) without giving your agent carte blanche?
- How do you ensure your RAG-powered agent only accesses documents the user actually has permission to see?
These aren't edge cases - they're fundamental requirements for any AI agent that's going to interact with real user data and take real actions.
What We Built
Auth0 for AI Agents gives you four key capabilities:
1. User Authentication
Secure and scalable User Authentication allows you to identify who's talking to your agent and give it secure access to your first-party APIs. Your agent can access user-specific data like order history, preferences, or chat logs - all scoped to the right permissions.
2. Token Vault
Token Vault handles OAuth flows with 30+ pre-integrated apps (GitHub, Slack, Google Workspace, and more) plus any custom OAuth provider you want to connect. It manages access tokens, refresh tokens, and the whole lifecycle automatically. Your agent requests a connection, the user authorizes once, and you never have to think about token management again.
The SDK detects when a tool call needs authentication, pauses execution, prompts the user to authenticate, stores the token securely, and resumes automatically. On subsequent calls, it just works.
3. Asynchronous Authorization
Your agent can work in the background and only interrupt the user when it needs approval for critical actions. Using Client-Initiated Backchannel Authentication (CIBA), you can send approval requests via email or Auth0 Guardian (SMS coming soon).
4. FGA for RAG
When your agent uses Retrieval Augmented Generation to search through documents, it needs to respect access controls. Fine-Grained Authorization for RAG ensures that users only get answers from documents they actually have permission to access.
Why This Matters
AI agents are moving from demos to production. The difference between a hackathon project and a real product often comes down to handling auth correctly. We built Auth0 for AI Agents because we kept hearing from developers that this was the hard part - not the LLM integration, not the prompt engineering, but the secure, user-scoped access to real systems.
This isn't about adding features. It's about removing blockers so you can ship production-ready AI agents without building your own auth infrastructure from scratch.
Framework Support
We've built SDKs for the frameworks you're already using:
- LangChain (Python & JavaScript)
- LlamaIndex (Python & JavaScript)
- Cloudflare AI
- Firebase Genkit
- Vercel AI SDK
Each SDK handles the OAuth dance automatically, so you can focus on building your agent's capabilities, not wrestling with authentication flows.
Get Started
Our free tier includes two connected apps in Token Vault, async authorization, and all the core features you need to start building. As you scale, we have self-service plans that grow with you.
Early-stage startups can apply for one year of Auth0 free.

Great news! This is a much-needed step forward β Auth0 for AI Agents solves a big pain point by replacing hardcoded credentials with real, secure, user-scoped auth. With features like Token Vault, async authorization, and fine-grained access control, it makes building production-ready AI agents way safer and more scalable.
