Blockchain Based Password Free Authentication

The traditional workflow of authentication uses passwords as the security for any kind of account a person uses on the internet. Passwords are the bane of online existence as they are easy to forget, susceptible to getting stolen and a virtual doorway to one’s personal information. Studies have determined that given a choice, most people choose very weak passwords such as birthdays and phone numbers that make them easy to crack. According to Verizon Data Breach Investigations Report, 81% of data breaches are caused due to hacked passwords. This paper proposes a reliable, secure and efficient solution to manage authentication, to enable passwordless authentication by leveraging the power of Decentralised Digital Identity (DDI). The Internet makes it possible to exchange information between peoples, servers, corporates and Business Enterprises and makes security more and more secure. To truly eliminate all dependencies by using biometric for identification and to access personal and important information, this paper optimizes the standards and build platform using blockchain technology.
