Credentials authenticate the Tower user to launch Ansible playbooks, which can include passwords and SSH keys, against inventory hosts. You can also require the Tower user to enter a password or key phrase when a playbook launches using the credentials feature of Tower.
Create a new credential by browsing to and clicking on the Credentials link from the Settings () button.
When setting up additional credentials, keep in mind that the user you assign must have root access or be able to use SSH to connect to the host machine.
For the purpose of this Quick Start, a demo credential has been provided for your use.
