# Routers
We're almost there! The last step is to configure the `FastAPIUsers` object that will wire the user manager, the authentication classes and let us generate the actual **API routes**.
## Configure `FastAPIUsers`
Configure `FastAPIUsers` object with the elements we defined before. More precisely:
* `get_user_manager`: Dependency callable getter to inject the
user manager class instance. See [UserManager](../user-manager.md).
* `auth_backends`: List of authentication backends. See [Authentication](../authentication/index.md).
```py
import uuid
from fastapi_users import FastAPIUsers
from .db import User
fastapi_users = FastAPIUsers[User, uuid.UUID](
get_user_manager,
[auth_backend],
)
```
!!! note "Typing: User and ID generic types are expected"
You can see that we define two generic types when instantiating:
* `User`, which is the user model we defined in the database part
* The ID, which should correspond to the type of ID you use on your model. Here, we chose UUID, but it can be anything, like an integer or a MongoDB ObjectID.
It'll help you to have **good type-checking and auto-completion**.
## Available routers
This helper class will let you generate useful routers to setup the authentication system. Each of them is **optional**, so you can pick only the one that you are interested in! Here are the routers provided:
* [Auth router](./auth.md): Provides `/login` and `/logout` routes for a given [authentication backend](../authentication/index.md).
* [Register router](./register.md): Provides `/register` routes to allow a user to create a new account.
* [Reset password router](./reset.md): Provides `/forgot-password` and `/reset-password` routes to allow a user to reset its password.
* [Verify router](./verify.md): Provides `/request-verify-token` and `/verify` routes to manage user e-mail verification.
* [Users router](./users.md): Provides routes to manage users.
* [OAuth router](../oauth.md): Provides routes to perform an OAuth authentication against a service provider (like Google or Facebook).
You should check out each of them to understand how to use them.
