# Single Sign On

The **myConnectedFleet portal** supports **Single Sign On** (SSO) using the **OpenID Connect** standard.

**SSO** avoids the **myCoonnectedFleet portal** user having to remember another username/password combination as the user can access the **myCoonnectedFleet portal** using their company’s authentication details. 

To enable SSO for a user, use the API to set a value for the **external identifier** against the user. 

* The external identifier is used to associate a user in your Authorization Server to a user in the **myCoonnectedFleet portal**.
* The external identifier is returned by your Authorization Server once the user has been successfully authenticated by your Authorization Server.
* A **myCoonnectedFleet portal** user enabled for SSO cannot use the **myCoonnectedFleet portal** functionality to reset their password.
