What is single sign-on (SSO)? What is the difference between SSO and vBSSO?

Think about it: how many accounts do you have out there on the internet? 10? 20? 50? Seriously? Can you imagine trying to remember dozens of passwords? Secure? Yes. Easy? No way.
Luckily there is a way out of this awkward situation. It is using the SSO technology.

So, what does Single Sign-On (SSO) mean? Let's take a quick overview.

Single sign-on (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials. With SSO, a user logs in once and gains access to different applications, without the need to re-enter log-in credentials at each application.

SSO advantages:
✓Reducing password fatigue from different user name and password combinations
✓Reducing time spent re-entering passwords for the same identity
✓Reducing IT costs due to lower number of IT help desk calls about passwords

And, what is vBSSO?

vBSSO is a vBulletin plugin that helps you connect to different software platforms like content management systems, blogs, and online stores using a secure Single Sign-On.
It gives you an opportunity to access control of multiple related, but independent software systems. With this property a user logs in once and gains access to all systems without being prompted to log in again at each of them. And conversely, vB Single Sign-Off is the property whereby a single action of signing out terminates access to multiple software systems.

The vBSSO system has two components:

✓First, there’s a vBulletin plugin. vBulletin platform acts as a Master platform and creates an interface for authenticating, controlling access, and managing user profile data.
✓The second component is plugin for other platform (or Slave platform - like WordPress, Prestashop, Magento etc.) that teach it to talk to vBulletin and exchange data.

When users attempt to access a Slave platform, the vBSSO plugin redirects the user to the Master platform, where the user signs in. After successful authentication the web browser redirects back to the requested web application, and the user can access the application or web content (the main features of the vBSSO plugin are listed here).

When an already authenticated user accesses another web application, the vBSSO on the Slave platform retrieves the user's validated credentials, thus eliminating any need for the user to sign on again.

The vBSSO is multifaceted plugin and allows you to connect as many accounts and platforms as you have - allows control of 1 account across multiple platforms.

Have fun!

    Single sign on is a user authentication technique which helps to manage the same account credentials across all web properties of an organization. Nicely explains the difference between single sign-on and vbssso. The article worth to read. Thank you for sharing the article.
