+# How to Obtain a New Token for OpenShift from xterm
+
+OpenShift login tokens expire because they are, by default, valid for a limited time (e.g., 24 hours). One way to obtain a new token is by SSHing into the controller machine and 
+running the [relogin.sh script](https://github.com/dsariel/scripts/blob/master/OpenShift/relogin.sh). See the content below:

+and using a text-based web browser on the remote server if connecting via the web console is not an option. Follow these steps to obtain a new token and continue working with the cluster:
+
+## Steps to Obtain a New Token
+
+1. **Install a Text-Based Browser**\
+   Install `lynx`, a command-line browser, to access the token request page:
+
+   ```bash
+   sudo yum install lynx -y
+   ```
+
+2. **Retrieve a password for the `kubeadmin` user**\
+   If you are using the default `kubeadmin` user, retrieve the password from the installation directory:
+
+   ```bash
+   cat ~/.kube/kubeadmin-password
+   ```
+
+   Use this password to log in as `kubeadmin` in the browser interface during the next stage.
+
+3. **Access the Token Request Page**\
+   Use `lynx` to navigate to the token request page:
+
+   ```bash
+   lynx https://oauth-openshift.apps.ocp.openstack.lab/oauth/token/request
+   ```
+
+4. **Obtain a New Token**\
+   Once logged in, obtain a new token. The login command will look like this:
+
+   ```bash
+   oc login --token=sha256~<...> --server=https://api.ocp.openstack.lab:6443
+   ```
