# Connector variables
## Introduction
The **connector variables** tab displays any i[nstance-level, shared variables](/product-documentation/developer-hub/connector-builder/building-your-own-connector/2-connector-variables.md) that you defined in [Step 2: connector variables](/product-documentation/developer-hub/connector-builder/building-your-own-connector/2-connector-variables.md) - for example:
## Using a connector variable in your authentication method
If you want to use any of these variables in this authentication method, click the **use** button:
This copies the variable into the **auth variables** tab - for example:
Show me
From here, the variable is treated like any other [auth variable](/product-documentation/developer-hub/connector-builder/building-your-own-connector/3-authentication-methods/authentication-method-options/auth-variables.md) - you will need to set options to determine if/how this variable is displayed to users, and how any values for it should be passed in API requests for authentication.
## Removing a connector variable from auth variables
If you choose to **use** a connector variable- i.e. to copy it to the **auth variables** tab - but later change your mind - you can remove it by clicking the associated **trash icon** on the **auth variables** tab - for example:
This clears the connector variable from the **auth variables** tab but the original 'shared' connector variable remains available for future use.
