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 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
