text: **Important:**It is possible to log in as the OpenShift cluster administrator from any master 
  node without a password by connecting by way of**ssh**to the master node. 
  
  After successful authentication from a client, OpenShift saves an authorization token in the 
  user’s home folder. 
  
  To check your current credentials, run the**oc whoami**command: 
  
  <html>
          <head> <meta charset="UTF-8">
          <style>
          table, th, td {
              border: 1px solid black;
              font-size: 10px;
          }
          </style> </head>
          <body>
          <table frame="hsides" rules="groups" width="100%%">
              [html]<thead><tr><td>oc whoami</td></tr></thead><tbody><tr><td>admin</td></tr><tr></tr></tbody>
          </table> </body> </html>
  
  To log out of the OpenShift cluster, use the**oc logout**command: 
  
  **oc logout**
  Logged "admin" out on "https://ocp.domain.example.com:8443" 
  
  As an administrator, the**oc get RESOURCE_TYPE [RESOURCE_NAME]**command is used most 
  frequently. This command helps to get information about resources in the cluster. Generally, 
  this command displays only the most important characteristics of the resources and omits 
  more detailed information.
