Good thread with a subject I think a lot of people aren't necessarily thinking about so much. I have already set this up on the main, personal Gmail account I've had for 15+ years and the address "everyone" knows about. It's a fairly simple process technically speaking, but it's an odd feeling to prepare things for when you're dead. It's found on

The long and short of it is that you can specify when the "I'm dead" switch engages (3, 6, 12 or 18 months), the phone number for extra verification that you're actually still alive, the 1-10 people who should be notified, the mail that will be sent and the autoreply that will come into effect. You can also specify what account data to share. I.e. you
can leave out your account's search history.
I've already had a brief talk with my (20-something) daughter about it so she knows what to expect; a (very short) list of peripheral irl and online acquaintances that otherwise wouldn't know that I'm dead, the login details to
my password vault (in which ACF is also found), how to unlock my phone and my computer(s), the safebox in the basement and other stuff. The same info is in a note in the password vault. There's also some wishes for my burying ceremony (aka the very-lost-in-translation "walk across"). She already has future, official, formal power of attorney in case I'm legally incapacitated in some way, plus she's the benefactor of the life insurance and all my stuff.
But even though I was brought up with death being a natural thing and not some kind of taboo or a thing best not talked about, the "I'm dead, now what?" mail was very hard to write. But I thought it was better to do it before I knew my date.
