@github.awesome: What happens to your password manager if you’re gone tomorrow? After concussions and a documentary about memory loss, a developer built ReMemory: a cryptographic dead man’s switch using Shamir’s Secret Sharing.

Each share is an offline HTML file—no servers, installs, or internet—built to work even decades later. #github #opensource
