Authentication stands as an important pillar of cybersecurity in our digital world. Authentication is the process of verifying the identity of a user, device, or system to ensure that the person or entity attempting to access a resource is authorized to do so. Communication protocols like Secure Sockets Layer (SSL) use secret key authorization to ensure the security of data transfer, like between a web browser and a website. In a system that uses secret key authentication, the user and the system share a cryptographic session key that\u2019s only known to the two parties. Network authentication refers to the identification of users who are trying to gain access to a network or server. In addition to extra convenience, passwordless authentication can provide more security because many users continue to use weak passwords or fall victim to phishing attacks that attack credentials.<\/p>\n<\/p>\n
