Verify the macOS system is configured to not allow automatic logon with the following command:

/usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep "DisableAutoLoginClient"

"com.apple.login.mcx.DisableAutoLoginClient" = 1;

If "com.apple.login.mcx.DisableAutoLoginClient" is not set to "1", this is a finding.
