Sell shares without Tpin and otp

I sold a share (T1) yesterday without Tpin and otp. I am confused and how is it possible.

Request you to please share the screenshot of the scrip you sold yesterday, on feedback@dhan.co. will get this checked.

The same is happened with me.
But I think when you will buy and sell the shares on same day. Dhan don’t ask for Tpin. But if you sell shares next day. Dhan will definitely ask for Tpin
