Signature Regarding Doubt

I want to know that can I keep different signature in demat account as of in Aadhar Card and Pan card? Or it is necessary to have the same signature in demat account which I have in the Aadhar and PAN card. Can anyone please tag zerodha officials.

A signature is used for the verification within the respective departments. You can have different signatures in different accounts but when you’re about to verify yourself using signature make sure to do the same signature which is there in the account already. As long as you are able to verify yourself no matter how many signatures you have in how many accounts.
