# Can I use my credentials in both Sandbox and Production environments?

Understand the separation of credentials between Sandbox and Production environments.

No. Each environment is separate, and each has its own credentials. If you have a Sandbox account, you cannot use that account to log on to Production, and vice versa.

When you receive credentials for AvaTax, it’s important to note which account the credentials are tied to (whether Sandbox or Production). We keep Sandbox and Production credentials separate to help you test your software in Sandbox without the risk of accidentally affecting production data.

If you don’t have access to the Sandbox environment, contact your account admin to add you as a user. More information about adding users is available [in this Knowledge Center article](https://knowledge.avalara.com/bundle/dqa1657870670369_dqa1657870670369/page/Add_a_user_and_set_permissions.html).
