When we discussed single sign-on, we mentioned how you can have another application log you into Help Desk. From the perspective of the user logging-in, this happens in the background. They do not see the log-in screen for your ActiveCampaign product:

Rather, they log-in to an entirely different application, and upon successful authentication, they are simultaneously logged-in to your ActiveCampaign product. When they visit the ActiveCampaign product, they are not required to log-in, which provides a more seamless experience.
Login sources could be considered the opposite – instead of logging into another application, you log directly into the ActiveCampaign product with credentials from that other application.
The difference is the log-in screen presented to the user. With SSO, it’s the external application log-in screen. With login sources, it’s the ActiveCampaign product log-in screen.
They are both achieving the same result, but where you log-in is the difference.
This illustration may help visualize this concept:

Above, you’ll see that as your ActiveCampaign product sits in the middle, you either authenticate to ActiveCampaign from single sign-on, or from ActiveCampaign to a login source.
Either way, your users gain access to your ActiveCampaign product in a manner more conducive to your business needs or system flow.
