Blockchain is being hailed as one of the most revolutionary and disruptive technologies out there. Blockchain has been disrupting the cybersecurity solutions-based CIA security triad principle. 2FA has been critical in security measures for several years; however, attackers sometimes manage to compromise these systems. We will understand how blockchain can transform the 2FA system to achieve an improved security method.
By design, blockchain is a decentralized technology that allows transactions of any kind of value among multiple participants without the involvement of a third party. By leveraging blockchain, we can ensure that this sensitive information never remains on one database; instead, it can be within blockchain nodes that have immutability and can't be modified or deleted. The following diagram shows a blockchain-based 2FA.
In this system, user devices will be authenticated by a third-party 2FA provider through the blockchain network...
