There is a way to SSH from a device into your Ubuntu Shell™ without needing to input a password.
First, on your client device, generate an RSA key-pair.
Next, on your Shell™ console, go to SSH Keys -> Create (this will create a new SSH key in your SSH key chain) and paste your public SSH key that you just generated in the provided space.
Next, click edit for your shell Shell™ from the dashboard, go to reinstall, scroll down to Change your Shell™ SSH keys, and select the keychain that contains the public SSH key of the client device. Reinstall the Shell™ (note that this will wipe any unsaved work), and your public key should now be in your Shell™'s ~/.ssh/authorized_keys file.
To double-check, run the following command in the terminal of your Shell™:
You should see your recently added public key from your client device printed to the terminal.
Congratulations! You should now be able to SSH from your client device to your Shell™without needing to input a password. The exact SSH process can be found here.
