Personal peer-to-peer vault. Zxbase is a free, open-source personal vault replacing legacy password managers and cloud solutions. Encrypts and syncs all your mobile and desktop devices peer-to-peer. With Zxbase - short for Zero Exposure Base - you build your personal vault by pairing your own devices. The data is transferred directly between devices (peer-to-peer) and never through the cloud. All communication is encrypted point-to-point. Encryption keys are never available to the Zxbase service. Zxbase doesn’t collect PII (Personally Identifiable Information) about its users. It only knows the Zxbase Identity Key, consisting of a public key and a unique identifier. • • • ORGANIZE SECRETS • Organize all your secrets in one place. • Create strong, unique passwords.
