Ask HN: What's your death plan? Deadman switch?

Curious about what folks have concocted as best practices upon death regarding passwords / accounts / keys / securities / etc.

Do you have a deadman switch? Have you "tested" it?

Do you have your master password (to a PW manager) printed and in a safe?

Considering the technical nature of certain post-mortem unraveling, have you designated a particularly competent friend as executor?
