AbsentKey – Secure, timed sharing of passwords and private data

Summary: AbsentKey is a zero-knowledge encrypted vault for sharing passwords, files, and private information with trusted contacts. It lets you control exactly when recipients gain access by approving or denying requests or setting a timeout from instant to one year. Data is end-to-end encrypted using libsodium, and servers store only scrambled information.

What it does

AbsentKey enables request-based access to sensitive data, allowing you to approve, deny, or automatically release secrets after a set waiting period. Its clients are open source for cryptographic verification.

Who it's for

It is designed for users needing secure, controlled sharing of private information with trusted individuals.

Why it matters

It solves the problem of inflexible emergency access by providing a transparent, user-controlled timed release of secrets without exposing data to servers.
