Moniker has their "Domain Maxlock" feature:
How it works:
Upon sign-up:
- Provide a government I.D. number for verification of your identity.
- Set-up custom security questions and answers, further safeguarding your domain assets.
To perform critical functions that affect your portfolio:
- Login to your account
- Answer your two custom security questions
Your custom security questions & answers can NEVER be retrieved or modified online. All modifications must be done through our security team after a thorough off-line verification process has been completed.
