What is remote login?
You can use Ubuntu as a remote desktop client straight from the login screen using Ubuntu'sfeature. This means you don't need a local account on the client computer. The Remote Desktop Protocol is the only supported protocol so far.
The system is designed so that Ubuntu One securely stores your login information so that instead of needing to remember your credentials for multiple remote computers, you can just enter your Ubuntu One email and password to log in.
Ubuntu also includes the Remmina remote desktop client if you'd prefer to connect to remote computers while logged in as a regular user.
