Secure Shell Connection Method
Secure Shell (also called SSH) is the default connection method. The Secure Shell protocol provides a secure alternative to Telnet, rexec, rlogin, or rsh. Secure Shell connections require both host and user authentication, and all communications pass between hosts over an encrypted communication channel.
Saved passwords are not supported for Secure Shell connections. Depending on how your host is configured, you may see a simple password prompt when you connect, or you may be prompted for addition information.
The Secure Shell protocol also supports the user of public/private key pairs or certificates for user authentication. For details, see Set Up Secure Shell Connections.
