Answer options

• A. PAMAuthentication
• B. ChallengegeResponseAuthentication
• C. PermitPlaintextLogin
• D. UsePasswords
• E. PasswordAuthentication

To completely disable password-based logins, both ChallengegeResponseAuthentication and PasswordAuthentication must be set to 'no'. The other options, while related to authentication, do not directly prevent password logins as effectively as these two settings.
