Secure Shell is a network protocol that allows data to be exchanged using a secure channel between two networked devices. SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, rendering them susceptible to packet analysis. The encryption used by SSH is intended to provide confidentiality and integrity of data over an unsecured network, such as the internet.
Secure Shell access is for advanced users who wish to have command line access to their web hosting accounts to make changes directly on the server. To enable SSH, you need to log into the Account Manager and click on the Secure Shell tool under the Website Settings section. You can then enable, or disable, Shell Access as well as define the Shell Interpreter, then click Update to finish the process.
Please note that once you have enabled SSH, your account access information will be listed in the Secure Shell section in the Account Manager. You must use those settings if you wish to use SSH to access your web hosting accounts.
