For non-POA users, to sell their stocks under Demat holdings it is mandatory to authorise the sell trades/ transactions with a TPIN from CDSL.

Once approved from CDSL, authorisation gets applied to all stocks under Demat holdings for that trading day.

Eg. User has 5 stocks under Demat holdings as

Stock Name	Quantity
Reliance	10
TCS	4
Infosys	66
ITC	12
SBIN	43

Now, if a client placed a sell request for 2 quantities of Reliance, he/she will be asked to authorise the transaction with a TPIN. Once TPIN is authorised at CDSL, all the stocks under his/her holdings get authorised automatically. Clients now can place sell orders on any of the stock under holdings without authorising again at CDSL.

What if the client wishes to remove shares from the authorisation list?

To do so, the client can use ‘Revoke shares authentication’ and select stock he/she wishes to unauthorise. Once unauthorised, the client has to again undergo the CDSL authorisation process if he/she wishes to sell the stock again the same day.
