# Command-line

Secure Shell (SSH) is a cryptographic network protocol to access the command-line interface. The WiFi extender offers various ways to access the command-line interface.

## **Web Terminal** <a href="#web-terminal" id="web-terminal"></a>

After accessing the admin, go to `System` > `Terminal`. Input the default username `root` and the extender password. You will then receive the welcome message on the web terminal interface.

*\* The web terminal is unavailable under the Traversal Cloud mode.*
