For someone else
If everything else in this series is about getting organized, this is the single artifact that makes it usable by someone else: one page, findable by the people you trust, that says where everything is and how to reach it. Not the keys themselves — a map to them. It's the difference between "it's all handled" being a feeling and being true.
Think of it as the note you'd want to find if the roles were reversed — calm, short, and enough to get someone started on a hard day.

One page
Made to be found
A single page, kept where the people you trust will look, saying where everything is and how to reach it. Because it's a map and never the keys themselves, finding it can't hand your life to a stranger.
The sheet
What goes on the page
Keep it to four things — enough for a trusted person to find their footing, none of it a key in itself.
Your emergency contacts, and the professionals: doctor, lawyer, accountant, insurer.
Which bank, which email, which phone carrier — named, so nobody has to guess where you bank.
The vault, the safe, the trusted person — how to get in, not the passwords themselves.
Allergies, key conditions, and where your directives or will can be found.
The one rule
Point to the keys — don't write them down
The sheet is a map, not a keyring. It should survive a lost phone and a changed password — and finding it shouldn't hand your life to a stranger.
Live passwords, PINs, full account numbers, security answers. Anything that is a key — it goes stale, and it's dangerous if the page is found.
A pointer to where the keys live and who can grant access — a vault, a safe, a trusted name.
Five minutes, every year and after any big change — a new phone, a move, a new account. A sheet nobody's touched in a decade is a sheet that misleads.
Keep the actual keys where they belong — in one place only you can read — and decide who can be let in if you can't do it yourself. When you're ready to fill it out, organizing your family's information walks through the rest.
Assemble once. Share on your terms.
Simply Once holds the details this sheet points to — encrypted so only you can read them, with trusted access ready for the day someone needs it.
