-6. Test if the Raspberry Pi is correctly configured by opening an SSH session to it (using its IP address). If this works the next step is to [add SSH public keys for each computer that should provision/connect to the Raspberry Pi](https://linuxhandbook.com/add-ssh-public-key-to-server/). **It's important to perform this step before provisioning because that will disallow logging into SSH with  a password.**
