End of Life Planning

As I age, I have been looking for a complete guide for end of life planning which would include all information pertaining to my family having access to info like passwords, legal contacts, insurance, monthly bills,etc as they transition into handling issues I deal with daily. there are several retail products available, like nokbox but I was trying to see if AARP has any product or recommendation. Unfortunately, there is nothing on the website nor the agent I spoke with had nothing as well.

Perhaps this might be something that could be explored as a benefit or product.
