It’s rare that this is needed, but sometimes it’s handy to just remove the access key rather than disable the whole module (especially if you’re using White Label).

To delete your current Security Admin Access Key, please follow these steps:

  1. Go to the Security Admin module
  2. Click the "Security Admin Settings" option
  3. In the "Security Admin Access Key", type exactly DELETE in both "Supply Password" and "Confirm Password" fields.
  4. Click to save settings and your current key will be deleted.

Then, you can set a new access key if you want.
