[Plugin: Spam Free WordPress] Disable or Remove Password field

Spam Free WordPress only works with the password field, otherwise all comments will be blocked if the visitor can’t type in the password. This problem will be solved by a new plugin that will be out soon. Check back in a few months.

New plugin is newest version of SpamFree WordPress, or other plugin?

The new plugin will be available on https://www.toddlahman.com in a few months.
