Hi Murielle,
There are two main types of integration on 3rd party sites - through iframes, and through LTI. In an iframe integration, you will see a button that allows you to log in on the top right corner of the Cerego learning application. In an LTI integration, an account will have been automatically created for you, and you will be already signed in.
Could you please provide some additional information on where you'd like to use Cerego?
