If you'd like to have any kind of arrangement like that for your account, the best way to do it is to include your password (or the password to your email account so they can reset your DW password) in your estate planning documents -- for instance, my wife and I both have the master passwords to our password managers in our files so anyone settling our affairs will be able to handle our online accounts as well. We don't require any personal information or identity verification when someone opens an account, so there's no way for us to verify that a user has passed away or that the person contacting us has legal authority over their affairs. We do have the ability to set accounts to "memorial" status, which indicates that the account is a memorial and the owner has passed away, and we'll apply that status when we're contacted by someone's next of kin, but we won't give out any access to the account, its contents, its login, etc.
