What are the Authentication techniques in information security?

There are various techniques of Authentication which are as follows −

Password-based authentication − It is the simplest approach of authentication. It needed the password for the specific username. If the password connect with the username and both details connect the system's database, the user should be strongly authenticated.

Vault authentication − In vault systems, authentication appear when the information about the user or machine is checked against an inside or outside system. The typical authentication forms for these systems are appearing through API or CLI.

Email authentication − There are several different approaches to email authentication. The typical used standards are SPF, DFIM, and AND DMARC. All of these standards additive SMTP because it doesn’t contain some authentication mechanisms.

Database authentication − In this method, authentication is important to make secure that the right people access a specific database to use the data for their work. In this case, authentication appears either with the Security Socket Layer (SSL) protocol or utilizing third party services.

Single Sign-on − SSO stands for Single Sign-on. It is an approach to enable access to multiple applications with an individual group of credentials. It enables the user to sign-in once, and it will automatically be signed in to all other web application from the similar centralized directory.

Social Authentication − Social authentication does not needed more security. Rather than, it can validate the user with the existing credentials for the applicable social network.

Passwordless authentication − In this approach, the user doesn't require any password. Rather than, it receives an OTP (One-time password) or link on the registered mobile number or phone number. It can also be said OTP-based authentication.

Multi-factor authentication − Most organization are warming up to the fact that truly secure identity management needed multi-factor authentication, defining two different authentication requirements, including a password and an eye-scan.

While one authentication factor can be hackable, it’s exponentially complex to hack two or more. Hand-in-hand with MFA are time-sensitive, one-time passwords. This method enables the user to acquire exclusive access to a password that will only operate for a short amount of time, creating it useless to steal after that period has dead.

Transaction Authentication − The transaction authentication method operate on the one-time identification number that is true for one-time use. The transaction authentication number insert a layer of security to the system creating it more secure.

Payment authentication − This type of authentication exists to provide that someone is not misusing other people's information to create online transactions. Sometimes, identity confirmation appears at least twice, or more. The typical approach are 3D secure, Card Verification Value, and Address Verification.

Server and network authentication methods − It can only like in any other form of authentication, network-level authentication methods validate that users are who they declare to be. In this method, the system categorize legitimate users from invalid ones. The typical forms are two-factor, tokens, computer identification, and single-sign-on authentication methods.
