The technologies and connectivity around the world have made it possible to access services offered anywhere in the world. This worldwide connectivity because of the internet, empowers and improves users experience towards the websites and businesses. Billions of transactions and other activities are not possible without this connectivity.
In order to gain access, users have to authenticate their identities first. Man invented several methods of authentications like seals, tokens, secret questions etc. But when it comes to digital the world, all the mentioned methods are of no use since they all are physical factors.
Users have to prove their digital identity to get access to services based on the internet. Some of the most common ways of authentication are social login, email login, using 2FA, etc.
In this article, I am going explain three different types of authentication methods.
Single factor authentication
When a single element from any authentication factor which is used as an identity factor, it is known as single factor authentication. Generally, in this type of authentication users have to verify their identities proving only single factor that is a password in most of the cases. SFA is the weakest level of authentication. The passwords alone are no more secure.
As I mentioned, the passwords alone are not secure enough. There is a need to add an additional layer. Two-layer authentication or 2FA is one such method. Here users have to verify their identities twice in order to get access.
The 2FA solution is secure and it is not possible for hackers to hack the systems protected with it. OTP verification, biometrics etc are some of the factors used as the second factor for 2FA.
Multiple factor authentication
When more than two factors are added to the list of verifying users identity, it becomes multi-factor authentication. The authentication offers an elevated level of security as users have to verify their identity by providing more than two factors.
The solution is applied where safety requirements are higher for example in banking systems, finance related businesses etc.
These are some of the three factors of web authentication. For any doubts and suggestions, please make a comment in the comment section below.
