Here are the steps to follow in case you want to revoke your Openstack credentials (for example if a user doesn't need credentials anymore or a user left or the credentials got compromised).

How to request

Openstack Application Credentials can be revoked by raising a ticket in the EWC Support Portal 

with the following information:

• Ticket Title : Revoke Openstack App Credentials Request
• Ticket Description including:

• • Tenancy Name (e.g.  ms-nmhs-project )
  • Owner (if different from the requestor)

The tenancy administrator (unless he's the requestor ) shall be included as participant to the request.
