When you create or edit a label, you can specify the label name and add comments.

You can also lock the label, which prevents other users from editing or applying the label. You lock a label to limit access to the label or ensure you apply a label once. For example, you might want to apply a label to a group of objects to indicate that you tested the objects and are ready to deploy them. After you apply the label, you can lock it to prevent users from editing the label or applying the label to other objects.
