Single Sign-On: Pros and Cons!

The single sign-on method of login to multiple websites is not a new technology. We know about it very well. Many businesses whether small or big had already integrated the technology to its websites. The need of single sign-on tool is increasing at an alarming rate. Everyone wants to provide seamless, easy and secure user authentication. Businesses know that today people have no time to spend on filling forms and going through frustrating user login process. They want everything quick and easy. And for this, there is no better option than the single sign-on solution.

If you are new to the term, don’t worry! You are at right place. I will explain to you all about SSO and what are the pros and cons associated with it and how it is going to benefits your business.

What is SSO?

SSO stands for single sign-on. SSO is a property of access control of multiple related but independent software system. That means by using this property a user can sign-in once and get access to all the systems without being prompted to login again and again at each of them. In simple words, we can say that it is a technology that provides users the ability to access more than one protected resource with one authentication credential.

SSO Pros:

Reduces password fatigue:

When you need to memorize a single username and password for your identity provider, instead of uncountable passwords for each system that you want to connect to, you get less frustrated or tired because of filling password only once. Forget the days of remembering separate passwords for different web services. Thus, single sign-on reduces the password fatigue.

Simplifies password and user management:

SSO is very important for IT administrators. If any of the employees is accessing multiple websites and wish to leave the organization then IT department only needs to decommission his/her account on the identity server to cancel access to all the service providers.

Improves productivity:

No doubt, by reducing the time of authentication, SSO improves the productivity. Users and IT team now can focus more on other works instead of spending their time on login and solving password request issues respectively.  

SSO Cons:

It doesn’t work if identity provider is down:

For any of the reason like due to an outage,  if your identity provider is not responding then the user cannot be able to access any of the web services or systems that are linked to it.
Although the single sign-on system is very secure but in case if a hacker hacks user account then he gets the access to all of the linked systems.

So these are some pros and cons of the single sign-on method, if you want to add further, let me know in the comments.
