Plaintext Authentication

Caution: Using plaintext credentials is not recommended. Use encrypted authentication methods when possible.

If a secure method of performing credentialed checks is not available, users can force Nessus to try to perform checks over unsecure protocols; use the Plaintext Authentication options.

This menu allows the Nessus scanner to use credentials when testing HTTP, NNTP, FTP, POP2, POP3, IMAP, IPMI, telnet/rsh/rexec, and SNMPv1/v2c.

By supplying credentials, Nessus may have the ability to do more extensive checks to determine vulnerabilities. HTTP credentials supplied will be used for Basic and Digest authentication only.

Credentials for FTP, IPMI, NNTP, POP2, and POP3 require only a username and password.
