title: "Can I add other users to my Phoenix Instance?"
---

Yes. Phoenix supports multiple users through [authentication](/docs/phoenix/self-hosting/features/authentication), with role-based access control, API keys, and OAuth2/SSO.

Enable authentication on your deployment, then invite team members and assign roles from the **Settings** page. See [Authentication](/docs/phoenix/self-hosting/features/authentication) for setup instructions.
