## Twilio Agent Identity

Turn your application into an OAuth 2.1 and OpenID Connect authorization server for AI agents. Let users grant scoped, revocable access to their accounts, and require human-in-the-loop approval for high-risk actions over Twilio channels such as SMS and RCS.

[Get started with Agent Identity](/docs/agent-identity/setup)

## Tutorial

```bash !sample
curl 'https://auth.example.com/.well-known/openid-configuration'
```

1. Configure your custom domain and RS256 signing keys in the Twilio Console
2. Integrate your existing authentication system with the Trusted Auth Token flow
3. Register the AI agent as a client and issue scoped access tokens

Tutorial code output: "Start authorizing AI agents in minutes."

## Set up Agent Identity

Configure your custom domain, signing keys, and consent screen, then register your first client.

```http
HTTP/1.1 200 OK
Content-Type: application/json
```
