Stronger Security.. MFA?

Hello Support. A great product which I have used since the early days. I’ve had a nagging concern for awhile about a single password protecting critically sensitive data. Has any progress been made to provide MFA validation on mobile and desktop versions of Codebook? I’ve seen the Mar 2017 discussion, “Stronger Security for Codebook” and was wondering what Zetetic’s final decision was.
Thank You.
