Technologies are emerging as fast as the blink of our eyes. Each day lots of new technologies are added to the existing list especially in the field of a digital world.
Digitization has changed the world, it changed the way we think and work. Everything has gone online today, so we have numbers of online resources to access on the daily basis. In short, numbers of accounts and associated credentials are growing continuously.
So, the numbers of passwords we need to remember are increasing alarmingly. This is seriously an issue, people hate passwords. They are a boring set of some numbers and alphabets. But don’t worry, here is a solution which can save users from remembering passwords.
The single sign-on method or SSO is one of the solutions that is tremendously gaining popularity among businesses with multiple online resources. The solution makes the authentication not only simple but also quick and secure.
In the article, we are going to understand three important standards and protocol behind the working of SSO solution.
The very first wide-spread standard protocol was OAuth that was released in the year 2010. The functioning of Twitter is based on OAuth. It is an open standard protocol which allows users authentication in a very simple and secure way.
The protocol allows end-users information to be used by third-party services such as Facebook without demanding their passwords. It acts as a mediator on the behalf of end users. It provides a token that authorizes specific account data and information to be shared.
The OAuth protocol is best for allowing users to post Instagram selfies to their Twitter account. In the year 2012, the second version of OAuth2 was released.
Next, comes the OpenID standard. It is a protocol that allows users to login multiple accounts, without the need of creating a new set of credentials. With this protocol, user’s password is only given to the identity provider. The identity provider confirms user’s identity for the applications they visit. Only the identity provider has the right to see user’s passwords, thus no other websites can have access to users passwords that make it secure.
The SAML protocol is next in the list. The SAML protocol is basically an authentication protocol that exchanges XML file between the authentication server and the website. In this protocol, a user requests a service from the service provider. The service provider obtains an identity assertion from the identity providers. Based on this assertion, the service provider makes a decision over access control.
These are the three most common SSO protocol standards. If you have any doubt or questions, feel free to mention them in the comment box.
