The Take

Client-side encryption, AES-256 blobs and Argon2id for the master password show the author really thought about attacker models; the missed check-in + beneficiary notification flow is a neat, practical UX for a fraught real-world problem. The idea itself isn’t new — password managers and legacy services already touch this space — so the product’s value will live or die on the nitty-gritty of recovery UX, legal edge cases, and how reliably that emergency trigger works in practice.

Post Description

I realized something uncomfortable about my life.

We’ve moved most of our lives online, like for banking, investments, subscriptions, crypto, cloud storage, etc. But what if someone needed to step in and manage any of it during a crisis? Not just access but clear instructions.

A secure way to document digital accounts so the people I trust know exactly what to do if they ever need to. It only gives them access when it's actually needed. Until then, everything stays encrypted and invisible.

Turns out I'm not the only one with this thought. So I turned it into Lineage: keeplineage.com
