Chapter 5. Managing user-owned OAuth access tokens

Users can review their own OAuth access tokens and delete any that are no longer needed.

5.1. Listing user-owned OAuth access tokens

You can list your user-owned OAuth access tokens. Token names are not sensitive and cannot be used to log in.

Procedure

  • List all user-owned OAuth access tokens: 

    $ oc get useroauthaccesstokens

    Example output

    NAME       CLIENT NAME                    CREATED                EXPIRES                         REDIRECT URI                                                       SCOPES
<token1>   openshift-challenging-client   2021-01-11T19:25:35Z   2021-01-12 19:25:35 +0000 UTC   https://oauth-openshift.apps.example.com/oauth/token/implicit      user:full
<token2>   openshift-browser-client       2021-01-11T19:27:06Z   2021-01-12 19:27:06 +0000 UTC   https://oauth-openshift.apps.example.com/oauth/token/display       user:full
<token3>   console                        2021-01-11T19:26:29Z   2021-01-12 19:26:29 +0000 UTC   https://console-openshift-console.apps.example.com/auth/callback   user:full

  • List user-owned OAuth access tokens for a particular OAuth client: 

    $ oc get useroauthaccesstokens --field-selector=clientName="console"

    Example output

    NAME       CLIENT NAME                    CREATED                EXPIRES                         REDIRECT URI                                                       SCOPES
<token3>   console                        2021-01-11T19:26:29Z   2021-01-12 19:26:29 +0000 UTC   https://console-openshift-console.apps.example.com/auth/callback   user:full

5.2. Viewing the details of a user-owned OAuth access token

You can view the details of a user-owned OAuth access token.

Procedure

  • Describe the details of a user-owned OAuth access token: 

    $ oc describe useroauthaccesstokens <token_name>

    Example output

    Name:                        <token_name> 1

    1
    The token name, which is the sha256 hash of the token. Token names are not sensitive and cannot be used to log in.
    2
    The client name, which describes where the token originated from.
    3
    The value in seconds from the creation time before this token expires.
    4
    If there is a token inactivity timeout set for the OAuth server, this is the value in seconds from the creation time before this token can no longer be used.
    5
    The scopes for this token.
    6
    The user name associated with this token.

5.3. Deleting user-owned OAuth access tokens

The oc logout command only invalidates the OAuth token for the active session. You can use the following procedure to delete any user-owned OAuth tokens that are no longer needed.

Deleting an OAuth access token logs out the user from all sessions that use the token.

Procedure

  • Delete the user-owned OAuth access token: 

    $ oc delete useroauthaccesstokens <token_name>

    Example output

    useroauthaccesstoken.oauth.openshift.io "<token_name>" deleted

5.4. Adding unauthenticated groups to cluster roles

As a cluster administrator, you can add unauthenticated users to the following cluster roles in OpenShift Container Platform by creating a cluster role binding. Unauthenticated users do not have access to non-public cluster roles. This should only be done in specific use cases when necessary.

You can add unauthenticated users to the following cluster roles:

  • system:scope-impersonation
  • system:webhook
  • system:oauth-token-deleter
  • self-access-reviewer
Important

Always verify compliance with your organization’s security standards when modifying unauthenticated access.

Prerequisites

  • You have access to the cluster as a user with the cluster-admin role.
  • You have installed the OpenShift CLI (oc).

Procedure

  1. Create a YAML file named add-<cluster_role>-unauth.yaml and add the following content: 

    apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
 annotations:
   rbac.authorization.kubernetes.io/autoupdate: "true"
 name: <cluster_role>access-unauthenticated
roleRef:
 apiGroup: rbac.authorization.k8s.io
 kind: ClusterRole
 name: <cluster_role>
subjects:
 - apiGroup: rbac.authorization.k8s.io
   kind: Group
   name: system:unauthenticated

  2. Apply the configuration by running the following command: 

    $ oc apply -f add-<cluster_role>.yaml
