I got mail form Nithin yesterday talking about new how Zerodha is debt free company and safe. It also stated that going forward in order to place order in CNC category you will have to apply 2 factor authorization. From when it is applicable? How it affects AMO?
If you’re placing a CNC sell AMO, you’ll be asked for 2FA while placing the AMO. There’s just an additional step. Nothing more. This is explained here: https://support.zerodha.com/category/trading-and-markets/trading-faqs/articles/pin-for-selling-holdings
Even after doing TOTP authentication, i was not allowed to place order in penny stocks for about 1-2 hrs and the problem then suddenly disappeared. I believe I will not face same issue from tomorrow.
