Ansible to change user password

One of the most basic things to do in a Linux Server. We can use just passwd <user> to change the password of a user. But to do that in 100s of server can be a tricky one. Ansible is the savior on that perspective.

---
- hosts: my100servers
  become: true
  tasks:
    - name: passwd change
      user:
        name: root
        password:  "{{ 'PLAIN_PASSWORD' | password_hash('sha512') }}"

Above playbook is well tested on linux systems.

$ ansible-playbook password-change.yaml
