I'm looking for an online service/app or something that my spouse should access immediately if I die

I had a neighbor who was recently killed in a car accident at 43 years old. He left a wife and two kids. We were not close friends but our kids hung out together. Unfortunately he managed all the payments, 401K's, bank accounts, credit cards, etc. etc. Since his death his wife has been struggling to get passwords, access to accounts, life insurance, credit card statements, etc. etc. It has really been a nightmare.

Is there some type of online service or software you can recommend where my spouse and I can both upload all our critical information (passwords, 401K info, life insurance, etc.) where neither of us have to go through this nonsense if the other one passes?

I tried on service called Trustworthy. I couldn't get the trial to synch with some of my important info such as my mortgage or a few credit cards. It's also $250/year. I'd love to find alternatives.
