The community.okd.openshift_auth module can be used, as the name suggest, to log into OpenShift.

---
- hosts: localhost
  module_defaults:
    group/community.okd.okd:
      host: https://api.openshift.example.com:6443
      validate_certs: False
  tasks:
  - block:

    - name: login
      community.okd.openshift_auth:
        username: john.doe
        password: itsasecret
      register: openshift_auth_results

    always:

    - name: logout
      community.okd.openshift_auth:
        state: absent
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
...

Taking this a step further, here is something a bit more practical, to return the list of all pods in all projects / namespaces.

- hosts: localhost
  module_defaults:
    group/community.okd.okd:
      host: https://api.lab001.op.thrivent.com:6443
      validate_certs: False
  tasks:
  - block:

    - name: login
      community.okd.openshift_auth:
        username: john.doe
        password: itsasecret
      register: openshift_auth_results

    - name: store all pods in all projects/namespaces in a dictionary named 'pods'
      kubernetes.core.k8s_info:
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
        kind: Pod
      register: pods

    - ansible.builtin.debug:
        var: pods

    always:

    - name: logout
      community.okd.openshift_auth:
        state: absent
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
