Information
To assure accountability and prevent unauthenticated access, privileged and non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system.
Multifactor authentication uses two or more factors to achieve authentication.
Factors include:
1. Something you know (e.g., password/PIN);
2. Something you have (e.g., cryptographic identification device, token); and
3. Something you are (e.g., biometric).
The DoD CAC with DoD-approved PKI is an example of multifactor authentication.

Note: Verify with the SA/ISSO as to the location of the "server_ca.pem" file.
MFA-URL = https://pmfa.example.com:6793/policyAuth/
