The most important asset I have is my bank account. In case of death, wife can take over (the only thing needed from wife is to proof she's my wife... so pretty much her ID card and marriage papers). That's it. Subscriptions? GitHub account with private side projects? Digital libraries? HN account? Email? All of that is not that important. If my wife has access to my bank account she can either transfer all of it to hers and effectively cancelling all my subscriptions or reject individual subscriptions manually.
