**Note**: if you don't use SSH keys for authentication, but rather a regular password, you may need to add `--ask-pass` to the above (and all other) Ansible commands.
**Note**: if you **do** use SSH keys for authentication, **and** use a non-root user to *become* root (sudo), you may need to add `-K` (`--ask-become-pass`) to the above (and all other) Ansible commands.
- **finalize the installation process** (required for federation to work!) by [Configuring Service Discovery via .well-known](configuring-well-known.md)
- or [create your first user account](registering-users.md)
