+    Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and; therefore, cannot be relied upon to provide confidentiality or integrity, and DOD data may be compromised.
+
+    {{{ full_name }}} systems utilizing encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules.
+
+    FIPS 140-3 is the current standard for validating that mechanisms used to access cryptographic modules utilize authentication that meets DOD requirements. This allows for Security Levels 1, 2, 3, or 4 for use on a general-purpose computing system.
