The family password notebook is a single point of failure

Most households have one. Bank logins in the back of a diary, a page of PINs in a kitchen drawer, or a note on one person's phone called IMPORTANT with every password the family depends on.

It's easy to see why. Paper is free, it works in a power cut, and everyone in the house understands it. Paper does have real strengths. One of them, that it survives things computers don't, is the reason our own Recovery Kit is a sheet of paper.

But as the *only* record of your family's passwords, the notebook lets you down in four ways.

Four ways it fails

There is only one of it. A fire, a flood, a burglary, or a house move where one box goes missing, and every account goes with it. Nobody made a copy, because copying it always felt like making things worse.

Whoever finds it can read all of it. The notebook can't tell your partner from a burglar. The moment someone finds it, every password in it is exposed at once.

It's always a little out of date. Passwords change and the notebook doesn't hear about it. The bank entry ends up two changes behind, the current password lives in one person's memory, and the notebook slowly turns into a list of hints.

Only one person understands it. Usually the person who started it. They know which crossed-out line is still current, what "the usual one" means, and that the electricity login is filed under the old supplier's name. It only works while they are around to explain it, which is exactly the situation it was meant to cover.

What safe sharing looks like

The fix has three parts.

A shared vault that is end-to-end encrypted. You each open it on your own phone, so there's no single object to lose, and a change made by one of you shows up for the other straight away. End-to-end encryption means the company storing it can't read the entries, and a vault is only as trustworthy as that. This is what the Passwords app in Vault For Us is for, but the idea matters more than the product. Any properly end-to-end encrypted vault you can both open is better than the notebook.

Share on purpose, not everything. Shared bills and the joint account belong in the shared space. Personal email doesn't have to. Sharing item by item lets you share the household without sharing everything.

Keep paper for the one job it's good at. A vault is protected by one secret, and that secret is what belongs on paper: a recovery code, written down and kept where the notebook used to live. One page instead of forty, and useless to a stranger without the rest.

What to do this weekend

This takes about an hour, most of it with a cup of tea.

1. Make the list. Sit down with the notebook, the phone note and the diary, and get every account into one list. About twenty minutes.
2. Sort it into three piles. Accounts you both need, personal accounts, and accounts nobody has used in years.
3. Close the dead ones. Every account you close is one less thing to protect.
4. Move the shared pile into a vault. As you add each one, change any password that is weak or used somewhere else. You're logging in anyway.
5. Write the recovery code on paper. Both of you should know where it is. This is the one page that still belongs in the drawer.
6. Retire the notebook. Shred it, or cross out every page. A half-retired notebook is worse than either system on its own, because nobody knows which record is right.

The goal isn't to become security experts. It's that on the day one of you has to manage alone, getting into the electricity account takes thirty seconds instead of an afternoon of guessing.
