  • Click Download the openrc file. The openrc file contains all the needed information for accessing the Openstack APIs. Keep it somewhere safe: its secret is shown only once, and is gone when you close the window.
  • Next, load the credentials (openrc file) in your terminal
source ./my-credentials.openrc

Note that the actual filename and path must be replaced with your own.
