Does Telnet have authentication?
Telnet is inherently insecure. Credential information (usernames and passwords) submitted through telnet is not encrypted and is therefore vulnerable to identity theft. However, users can establish an Secure Shell connection instead to prevent this type of intrusion.
What is Telnet used for?
TELNET is commonly used by terminal emulation programs that allow you to log into a remote host. However, TELNET can also be used for terminal-to-terminal communication and interprocess communication. TELNET is also used by other protocols (for example, FTP) for establishing a protocol control channel.
