Sharepoint 2013/2016 and Custom Web Api with custom database.

Question

How do I authenticate to a Custom Web Api from a SharePoint 2013/2016 single page app? I've seen a couple examples of using session which i really don't want to use, I'm thinking maybe a custom security token service or would it be better to add the web api as a provider hosted app (high trust) since this is on premises?
