I have learned today from a friend that Mitsu.in has enabled the two step authentication services. I have just logged in to my re-seller account and it has shown a banner to enable for two step authentication.
I have tried to test the same and it has worked like a charm. Its simple and easy to follow the on-screen instructions. Thank you logicboxes and Mitsu for bringing such service for .IN registrants. So now my domains at Mitsu.in are more secure. I really hope other logicboxes powered .IN registars will follow the same route and bring the similar services for registrants.
You want to enable the same and need more info then access the logicboxes help link @How to enable 2 step verification?
