When configuring a system with code, it is possible to use a credential that “belongs” to another org.

  - name: cicd-awx-ping
    job_type: run
    inventory: inv-cicd_test
    project: 'DEV/TEST ansible-awx'
    playbook: ping.yml
    organization: cicd
    execution_environment: 'Automation Hub Default execution environment'
    verbosity: '0'
    credentials:
      - "DevOps-awx_credential"
    state: present


  - name: DevOps-awx_credential
    description: local service account user
    credential_type: Machine
    organization: DevOps
    inputs:
      username: "svc.awx.admin"
      ssh_key_data: "{{ lookup('file','...........') }}"
    state: present

Templates should not be able to use credentials from another Organisation.

If you are an admin in AWX (I assume you are asking about AWX), you can assign a credential from any org to a job template. If you are a non-admin user, you are limited to the credentials in the org(s) you belong to. It’s a pretty easy thing to see for yourself.
