Password Autofill must be disabled.

macOS allows users to save passwords and use the Password Autofill feature in Safari and compatible apps. To protect against malicious users gaining access to the system, this feature must be disabled to prevent users from being prompted to save passwords in applications.

Check

Verify the macOS system is configured to disable password autofill with the following command:

/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowPasswordAutoFill').js
EOS

If the result is not "false", this is a finding.

Fix

Configure the macOS system to disable password autofill by installing the "com.apple.applicationaccess" configuration profile.
