What Is Authentication? How it's work with example 

Authentication is the confirmation of a user's degree of access to an account, platform, or private space. Users are typically recognized by a user ID, and authentication takes place when the user offers a credential, such as a password, that corresponds to that user ID. 

the confirmation of access to private space

Most users are acquainted with using a password, which is referred to as a knowledge authentication factor since it is a piece of information that should be available only to the user. 

Aside from guest accounts, auto logged-in accounts, and kiosk computer networks, most human-to-computer interactions have some form of user authentication.

 To access a system, a user must first pick a username or user ID and enter a valid password. User authentication authorizes human-to-machine interactions in operating systems and applications, as well as wired and wireless networks, allowing access to the network and internet-connected devices, applications, and resources.

Authentication is a method used by many organizations to verify users that connect to their websites. User data, such as credit and debit card information, 

as well as social security numbers (SSN), might get into the hands of hackers if proper security precautions are not taken.

The process of authentication is also used to recognize and regulate a user’s access to corporate networks, computers, servers and sensitive digital resources.

 It is also used by businesses to allow remote personnel secure access to their apps and networks.

Adding extra authentication elements to the verification process enhances security in most cases. A protocol is typically considered strong that entails the use of at least two factors, each of which is of a different type. 

Two-factor authentication is another name for it (2FA).

A user is encouraged by many organizations and exchanges to use two-factor authentication to safeguard their account data, especially in the world of cryptocurrency. 

The main reason for this is that, unlike your bank account, there is no fraudulent protection or method for recovering stolen assets if your crypto accounts get hacked!

It may take a little effort to learn and set up two-factor authentication, but the extra layer of security is definitely worth it.

Blockchain Authentication refers to systems that authenticate users' access to resources on multiple blockchains.

To secure wallets or the areas on the blockchain where currency or sensitive data is safely held, the blockchain employs public key cryptography (PKC). 

As a result, there are some fascinating parallels between blockchain technology and its security. Identity and access management (IAM) tools for blockchain usually come with cryptocurrency wallets as a primary feature, but you may end up compromising on the user experience (UX) and user interface (UI) interface part.

It is worth noting that cryptography experts and blockchain developers sometimes have overlapping interests, making blockchain developers an essential component of the security and innovation environment.

The ecosystem was in dire need of the modernization of technology in the early days of Bitcoin adoption and blockchain use cases, so the wider public with less technical knowledge could start using it without compromising their privacy and security. 

One response to this call was password-protected wallet applications with high-level authentication protocols.

 A genuine password-less interface in digital currency wallets and blockchain apps will solve this problem and will welcome more people into the next phase of these technologies' development and real-world use cases.
