+:::info User SDL
+We created a User model in Chapter 4 when we set up authentication for our blog. Redwood's `setup auth dbAuth` command generated two files for us that manage authentication: the `auth` file in `api/src/lib/`, and the `auth` file in `api/src/functions/`. Both of these files use our PrismaClient directly to work with the User model, so we didn't need to set up an SDL or services for the User model.
+
+If you followed our recommendation in the Intermission to use the Example repo, the User SDL and service is already added for you. If not, you'll need to add it yourself:
+
+```bash
+yarn rw g sdl User --no-crud
+```
+
+We'll comment out the sensitive fields of our GraphQL User type so there's no chance of them leaking:
