What Is Single Sign-On (SSO)? The Most Comprehensive Guide

Single sign-on, or SSO, is a unique implementation of access control. The purpose of single sign-on is to provide a streamlined process for authenticating users and authorizing them to access multiple applications using only one set of credentials.

Hi Guys Sumer Here with another exciting topic: SSO, What is it, How it works, and the benefits of using this technology.

What is Single Sign-on?

Single Sign-on (SSO) is a type of authentication that allows users to log into multiple applications using a single set of credentials. SSO eliminates the need for users to remember different usernames and passwords for each application or service.

what is sso

Large enterprises with many applications usually use single sign-on, but it can also be helpful for small businesses. In this article, we’ll walk you through some examples of how an organization can use SSO to improve security and usability for users.

A Simple Breakdown Of How Single Sign-on Works.

Single Sign-On (SSO) is a service that allows a user to sign into multiple applications with a single set of credentials. This can be done by storing the user’s login details on a central server, which then uses OAuth or OpenID Connect to grant access to any application that uses the same SSO provider. 

The Benefits of SSO

Below I mentioned the benefits of single sign-on technology that we are getting in today’s time.

  • SSO Provide Multiple Services with a single login
  • It saves our time to type password multiple time
  • It helps us get rid of the headache of remembering multiple passwords for a single company.

Disadvantages Of SSO

Although SSO is a great technology that many big companies use, there are some issues with this technology. Because of this technology, passwords are stored in a central server that is used to access other applications.

So if a central server gets hacked, then all our accounts will be hacked associated with that sso. But the possibility is very low because every big company implements this technology with highly-secured servers.
