My wife and I save all of our passwords and log-in details, and other important stuff in an Excel spreadsheet, protected with a complex password. Each of us have the same copy on our own laptops, and when either of us makes a change or addition, we highlight it in yellow and re-save. Then once a month I combine the 2 files into one making all of the changes to have one new file that is, at least for a while, up to date and the same on both machines. Both of our adult kids know the master password and can use the file when ever they need to. They both have Power of Attorney for both of us so, to say we trust them, is an understatement. It is my understanding that an Excel spreadsheet that is password protected is almost impossible to crack. I hope that I am correct in this. If not, I will have to find another method, but to date this works well for us.
