So that takes care of the ‘forgetting’ problem, unless, of course...

Well, you recognize one problem. But just in a general way, writing stuff down does not necessarily "take care of the 'forgetting' problem". My late mother-in-law lived to be 97. Never really suffered from dementia -- she was pretty cogent right up to her death. But her memory did decline as she got older. So somewhere in her '70s she started writing everything down. Then she started to forget where she'd put the notes. You can print out your 1Password 'emergency kit' but then you have to remember where you put it. If you put it in your desk drawer or safe at home, well, it might have been incinerated with the rest of the house (as you acknowledge). So you can put it in the bank, but see the OP above for problem of getting into bank. You can give it to your daughter to keep at HER house but then you have to remember that you did that, or she's got to remember that you gave it to her AND she has to remember where SHE put it. (My oldest daughter is a surgeon. Her memory's awesome for some things but absolute cr*p for others.) Not saying writing stuff down is a BAD idea. Print out your emergency kit from 1Password and give it to all THREE of your daughters. And then be nice to them.
