# Global Variables
Global Variables allow you to define and apply variables one time across all workspaces within an organization. For example, you could define a global variable of provider credentials and automatically apply it to all workspaces.
{% hint style="warning" %}
Workspace variables have priority over global variables if the same name is used.
{% endhint %}
### Creating a Global Variable
{% hint style="info" %}
Only users that belongs to Terrakube administrator group can create global variables. This group is defined in the terrakube settings during deployment, for more details see [#administrator-group](https://docs.terrakube.io/getting-started/security#administrator-group "mention")
{% endhint %}
Once you are in the desired organization, click the **Settings** button, then in the left menu select the **Global Variables** option and click the **Add global variable** button
In the popup, provide the required values. Use the below table as reference:
| Field | Description |
| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| Key | Unique variable name |
| Value | Key value |
| Category | Category could be Terraform Variable or Environment Variable |
| Description | Free text to document the reason for this global variable |
| HCL | Parse this field as HashiCorp Configuration Language (HCL). This allows you to interpolate values at runtime. |
| Sensitive | Sensitive variables are never shown in the UI or API. They may appear in Terraform logs if your configuration is designed to output them. |
Finally click the **Save global variable** button and the variable will be created
You will see the new global variable in the list. And now the variable will be injected in all the workspaces within the organization
### Edit a Global Variable
Click the **Edit** button next to the global variable you want to edit.
Change the fields you need and click the **Save global variable** button
{% hint style="warning" %}
For security, you can't change the **Sensitive** field. So if you want to change one global variable to sensitive you must delete the existing variable and create a new one
{% endhint %}
### Delete a Global Variable
Click the **Delete** button next to the global variable you want to delete, and then click the Yes button to confirm the deletion. Please take in consideration the deletion is irreversible
