Single Sign On

Single Sign On (SSO) is a system that allows users to log in once and securely authenticate to multiple apps and websites using a single set of credentials. (username and password). With SSO, the application or website that the user tries to access depends on a trusted third party to verify that the user is the person.

How Does Authentication Without SSO Work?

Without a single login, each website maintains its own user database and credentials. When you try to connect to an app or a website, here’s what happens:

The website first checks if it is authenticated. If you have one, you can access the site.

If you are not logged in yet, you are prompted to log in and verify your username and password against the information in your user database.

 

Once Connected

The site transmits authentication verification data when browsing the site to ensure that it is authenticated each time a new page is accessed.

Authentication verification data is typically passed as a cookie or token containing session data. Tokens do not follow sessions and are quick to process.
