66 Self-hosted environments are in public beta on Team and Enterprise plans; an [Owner](/docs/en/cloud-environments#organization-shared-environments) enables them by turning on **Allow self-hosted environments** on the [**Cloud environments** admin page](https://claude.ai/admin-settings/cloud-environments). This page covers session identity verification; see the [quickstart](/docs/en/self-hosted-environments-quickstart) for setup and [Deploy to production](/docs/en/self-hosted-environments-deploy) for the fleet recipes.

9A [self-hosted environment](/docs/en/self-hosted-environments) lets [Claude Code on the web](/docs/en/claude-code-on-the-web) sessions run on infrastructure you operate instead of on Anthropic's. Because the session runs inside your network, Claude can call your internal services directly. Those services need a way to confirm that a request really came from a Claude Code session in your environment, and to identify the user or service identity that created that session.

1111Every session in a self-hosted environment receives a signed JSON Web Token (JWT) in the `CLAUDE_CODE_SESSION_ACCESS_TOKEN` environment variable. A session presents the token like any bearer credential; for example, a script Claude runs can call your service with `curl -H "Authorization: Bearer $CLAUDE_CODE_SESSION_ACCESS_TOKEN"`. Anthropic signs the token and publishes the verification keys at a public JWKS endpoint. Your services fetch those keys, verify the signature, and read the claims to decide what access to grant.
