Question about how to use 1password within playbooks

Personally I would recommend using SSH keys over passwords and use the 1password SSH agent for the connections. This works really well. Though you did say you were running Ansible on a server so if you are SSHing into that server SSH agent forwarding would also work as mentioned in this thread: https://1password.community/discussion/127482/feature-request-using-1p-ssh-from-inside-a-local-docker-container

If you are insistent on using passwords, use one of the variables documented here and set it using the onepassword filter in either groups_vars/all.yml or host_vars/hostname.yml for specific host passwords:

yaml
ansible_ssh_password: "{{ lookup('community.general.onepassword', 'server1_login', field='password', vault='Private') }}"


PS if you are using op CLI v2, make sure you update the community.general ansible collection to 6.3.0 to get the v2 patch.
