BDP

BidiPass (BDP) describes itself as an identity authentication protocol built on Ethereum.

The BidiPass Authenticator aims to offer decentralized 3FA for enhanced infrastructure security. The BidiPass platform aims to offer a user-friendly, secure, and reliable method to authorize actions within connected platforms (e.g. approving transactions on a trading platform) by using a two-layer security protocol that operates in a distributed, peer-to-peer manner. The BidiPass blockchain architecture is based on a hybrid approach which combines private and public blockchains in order to achieve security, performance, and low operational costs.

BidiPass's goal is to create a solution that will adapt to technological innovations and greater infrastructure security in the long term. More information here: https://bidipass.org/
