# What does 'user limit reached' mean in testing?

Testing and staging environments have a **fixed cap on connected users each**. Hitting the cap blocks new authentications and can surface as a 'User Limit Reached', rate-limit, or quota error.

To free up slots:

* **Deauthenticate unused test users** from the dashboard's [users page](https://github.com/tryterra/api-faqs/blob/main/dashboard/README.md) (or via the `deauthenticate` endpoint).
* Contact support if you need more test users.

Production credentials are event-based and have no user cap (billed per user). See [understanding Terra environments](https://docs.tryterra.co/health-and-fitness-api/integration-setup/understanding-terra-environments) for more.
