I asked the same question to the delivery executive, whom I know quite well since he mostly delivers in my area.
He said that they have both option while delivering and it depends on the delivery executive. Usually, they ask for the OTP if they are delivering to someone other than the original recipient.
In my case, I received two different OTPs (one for the cheque and one for the debit card), but I didn’t provide any of them to him, and he still successfully delivered both.
Unless the seal 👀 on the package is broken, I honestly don’t think anyone needs to worry.
