# 🔌 SSO

# The principle

Single Sign-On (SSO) is the feature that allows a user to authenticate once for the duration of a session regardless of the number of applications that require authentication. Then, users can directly access their data, without enter a new pair of username / password again.

# The goal

To work, the ComexposiumConnect widget must be installed on all pages of your application / platform. Once the widget is installed, you can create an account and test SSO connexion.

# How it works

Once the widget is correctly installed and initialized, the transition from a Comexposium platform to your application / platform must be possible without the user need to connect again.

To ensure the operation from one of the Comexposium platforms to your application / platform, you have at your disposal all the methods offered by the Comexposium API in addition to those available below.

You can accept by connecting threw the SSO connexion, or you can refuse and disconnect.
