I forgot the password of the certificate of deposit made with grandpa's ID card. Grandpa has passed away. What should I do? Seek an answer

Hello, because your grandfather has died and his household registration has been cancelled, according to relevant laws and regulations, your grandfather's household registration information can't be found on the public security network, and the public security network is the identity information provider of the bank, so the bank can't find your grandfather's information.

Normal certificates of deposit don't need any formalities to pay, but now I have to report the loss because I forgot my password to pay. Specifically, you can provide a copy of your grandfather's death certificate (the original has been recovered) and your grandfather's notarized and legally effective property distribution will (if there is no will, I suggest you consult the bank and what supporting materials you need to provide. The general bank will ask for a household registration book or other proof that you are an immediate family member, which is included in the street letter).
