Securing Your Crypto: Understanding Authentication
Authentication is a procedure that verifies a user’s identity using passwords, SMS codes, fingerprints and other forms of proof of ownership before granting access to sensitive and/or personal information.
What is authentication?
Authentication is the verification of a user’s degree of access to an account, platform, or personal space. Typically, users are recognized by a user ID, and authentication occurs when a user offers credentials, such as a password, that match that user ID. Most users are familiar with the use of a password, which is called the secret authentication factor, because it is a piece of information that should only be available to the user.
In addition to guest accounts, auto-login accounts, and computer centers, most human-computer interactions have some form of user authentication. To gain access to the system, the user must first select a username or user ID and enter the correct password. User authentication authorizes human-machine interactions on operating systems and applications, as well as on wired and wireless networks, providing access to the network and Internet-connected devices, applications, and resources.
Authentication is a method used by many organizations to verify users who connect to their websites. User data such as credit and debit card information and Social Security numbers (SSNs) can fall into the hands of hackers if proper security measures are not taken.
In most cases, adding additional authentication elements to the verification process strengthens the level of security. As a general rule, a protocol that involves at least two factors, each of which is of a different type, is considered strong. Another name for it is two-factor authentication (2FA).
Learning and setting up two-factor authentication may take a bit of effort, but the extra degree of security is definitely worth it. Blockchain authentication refers to systems that authenticate user access to resources on multiple blockchains.
To protect wallets or areas on the blockchain where currency or sensitive data is stored securely, blockchain uses public key cryptography (PKC). Thus, some interesting parallels can be drawn between blockchain technology and its security. Identity and Access Management (IAM) tools for blockchain usually come with cryptocurrency wallets as a core feature, but you may end up compromising on user experience (UX) and user interface (UI).
It should be noted that the interests of cryptographers and blockchain developers sometimes overlap, making blockchain developers an important component of the security and innovation environment.
A password-free interface in digital currency wallets and blockchain applications will solve this problem and attract more people to the next phase of these technologies and real-world scenarios for their use.
