## About Workflow Variables

You can define personal variables for use in workflow expressions. Variables you create here are available in your workflows through the `var` context — for example, `${{ var.MY_VARIABLE }}`.

Personal variables are separate from your organization's variables, which use the `org` context and are managed by organization admins. For more information, please see [**Organization Workflow Variables**](/docs/organization-admin/settings/variables).

## Adding a Variable

Navigate to your account settings (**Username** > **Account**). On the next page, click **Variables**.

Click **Add variable**.

In the dialog box that appears, enter a **Key** (letters, numbers, underscores, and hyphens only — for example, `MY_API_KEY`) and a **Value**. Click **Save**. A dialog box with the message _Variable created_ will appear.

Variables are stored as secrets by default: their values are masked in the variables table and can't be viewed again after saving.

## Editing and Deleting Variables

To change a variable's value, click the edit icon in its row, enter the new **Value**, and click **Save**. A variable's key can't be changed after creation; to rename a variable, delete it and create a new one.

To delete a variable, click the delete icon in its row. A dialog box will appear; click **Delete** to confirm.

## Using Variables in Workflows

Reference your variables in any workflow definition with the `var` context:

```yaml
jobs:
  main:
    steps:
      - name: Run
        run: echo ${{ var.MY_VARIABLE }}
```

For more information about contexts and expressions, please see [**Inputs and Expressions**](/docs/run/workflows/building-workflows/inputs-and-expressions).
