My parents. All written down on paper in handy notebooks for anyone that breaks in. Two entire lives and everything in them just there for the taking.
If I recall, a few (most) security experts now support written-on-paper passwords. Why? Because it is the solution for users who would otherwise commit far a more egregious security faux pas otherwise.
In most circumstances, it is easier to keep the notebook secure than your wallet, your car, etc. And let’s be honest, the list of suspects are REALLY short if someone breaks into your house, opens the third drawer, grabs the notebook and runs. And if it’s more than that and somebody ransacks your entire house, I guarantee having to change your passwords is the least of your headaches.
Ultimately, physical compromise is the lowest possible security risk for most people throughout their lives. Yes, it happens. Yes, it sucks. But having your bank password out in the wild with nobody realizing it is possibly far more dangerous.
My grandma does this, but they’re in one of the many Bibles she has in her home.
