If we go a few years back, login to a network or resource is not a big hassle. Although the login process was very complex, but at least you had to do it once. The reason was, you only had one network to login. But today, the scenario is totally different. With the advent of web followed by cloud resources, the number goes to dozens and things get complicated. This is the main reason, why the concept of single sign-on is gaining popularity. With this, the user no longer needs to remember dozens of passwords.
Single sign-on or SSO solution is now required more than ever. Nowadays, to access the content of almost every website, authentication is required. With the rise of websites and online applications, centralized authentication has become a necessity.
There are many businesses who have multiple websites of their own. Because of that web development teams are facing a very common problem: they have developed a service at domain A and they want their new deployment at domain B by using the same login details as they used for domain A. In fact, they want more, they also want users to automatically login to domain B if they already logged in to domain A. This is what all about single sign-on technology.
How does it work?
Different SSO protocols share information in different ways but the concept is same for all. All the information and session is shared with domains under SSO, once the authentication is done by central domain. When a user attempts to authenticate systems that are protected with SSO, central domain generates a JSON web token and distributes among all related domains. When the user attempts to authenticate other related domains then a redirection is sent to the central domain for verification.
Once the token is verified by central domain, user gets the permission to access services. This all process is done backhand. End users only need to login to any of the application and will automatically get access to all related applications.
SSO solution is a perfect solution for such businesses who want to offer the best authentication experience to their users. The solution not only saves users time but also helps in improving productivity. So, if you are still using the old traditional ways of authentication for your business websites, it is a peak time to implement the single sign-on solution.
