If your app uses GraphQL. You are ready to go. Just spin up a Dgraph Cloud env and good to go. You just need to use all the Auth goodies in your Schema. It will work like a charm after you design your schema model.
If you wanna use DQL on the other hand. You gonna have to build an API. And there are other extra steps to secure your GraphDB.
Hum, you are probably looking for GraphQL indeed. The Auth feature supports some third-party auth. I’m not 100% aware of this, I gonna ping @amaster507 .
