Why each option
This question asks to identify the network protocol that transmits authentication credentials, specifically passwords, in an unencrypted clear-text format during the login process.
Telnet is an unencrypted network protocol used for remote login and command-line communication, which means all data, including usernames and passwords, is transmitted in clear text across the network. Its lack of encryption makes it highly vulnerable to eavesdropping and interception, rendering it insecure for authenticating users over untrusted networks.
HTTPS (Hypertext Transfer Protocol Secure) encrypts HTTP communication using SSL/TLS, protecting data such as passwords during web transmissions.
