+### Using Linked Custom Fields
+
+Linked custom fields can be used to solve issues where your Browser Extension can't auto-fill usernames and passwords for a particular site. To create and auto-fill a Linked custom field:
+
+1. In the **Custom Fields** section of a Vault item's **Edit Item** panel, choose **Linked** from the dropdown and select {% icon fa-plus %} **New Custom Field**:
+
+   {% image features/linked-custom-field.png Add a Linked Custom Field %}
+2. In the **Name** input, [give the custom field a name]({{site.baseurl}}/article/custom-fields/#custom-field-names) that corresponds to the username or password's HTML form element `id`, `name`, `aria-label`, or `placeholder`.
+
+   {% callout success %}You can get the right value by right-clicking the form element and using the **Copy Custom Field Name** context menu option:<br><br>{% image features/custom-fields-contextmenu.png %}{% endcallout %}
+3. From the **Value** dropdown, select **Username** or **Password** depending on which credential you're having trouble auto-filling. In many cases, you'll need to create a Linked custom field for each.
+4. **Save** the changes to your Vault item.
+
+Now that you've created one or more Linked custom fields, you can auto-fill using the [method described in an earlier section](#auto-fill-custom-fields). When you do, your Browser Extension will auto-fill the username, password, or both into the HTML form element given for a field Name.
