What's the difference between a Service and Authentication?

There are nuanced differences between a custom Authentication Service and an Authentication created using that service. At a high level:

• The auth service is really a custom template that you define in order to create individual authentications.
• An authentication can then be instantiated using your pre-defined template (the service).
• This arrangement allows you to create multiple authentications which fit an API authorization schema.
• However, each authentication API Key and Secret Key are unique to the individual authentication that you define rather than the auth service. Remember, the service is just the template.
