Before connecting to a new host, Remote Desktop Connection asks for the settings that most often need a change: the display size, and the sound or connection type. Click All Settings… to see every setting for the host, and to give the connection a Name that the connection list shows instead of its address. The settings are grouped the same way as the default settings of the protocol in the Plugins preferences: Display, Local Resources, and for RDP Connection (session, gateway, proxy, and SSH tunnel) and Security. Click Connect to connect with the chosen settings. Clear Show this dialog again for this host to reuse them without being prompted on each connection. Settings are associated with the connection address; connecting by a different host name or IP address can use a different configuration.

When the server requests authentication, enter your password and, if requested, your user name. The Remember password option allows Remote Desktop Connection to store the entered password through the system credential store using QtKeychain after authentication succeeds. The choice is remembered for this host. Previously saved passwords remain available even when this option is unchecked. The global Remember passwords setting controls both reading and saving passwords; when it is disabled, the authentication dialog does not offer to remember the password.

For RDP, Remote Desktop Connection may ask you to verify an unknown or changed server certificate. Check the certificate details with the server administrator before accepting it. The dialog offers Remember this certificate for subsequent connections.

The tab icon indicates connection status. After authentication succeeds, you can view or control the remote desktop.
