# MongoDB
**FastAPI Users** provides the necessary tools to work with MongoDB databases thanks to [mongodb/motor](https://github.com/mongodb/motor) package for full async support.
## Setup database connection and collection
Let's create a MongoDB connection and instantiate a collection.
```py hl_lines="6 7 8 9 10 11"
{!./src/db_mongodb.py!}
```
You can choose any name for the database and the collection.
!!! warning
You may have noticed the `uuidRepresentation` parameter. It controls how the UUID values will be encoded in the database. By default, it's set to `pythonLegacy` but new applications should consider setting this to `standard` for cross language compatibility. [Read more about this](https://pymongo.readthedocs.io/en/stable/api/pymongo/mongo_client.html#pymongo.mongo_client.MongoClient).
## Create the database adapter
The database adapter of **FastAPI Users** makes the link between your database configuration and the users logic. It should be generated by a FastAPI dependency.
```py hl_lines="14 15"
{!./src/db_mongodb.py!}
```
Notice that we pass a reference to your [`UserDB` model](../models.md).
!!! info
The database adapter will automatically create a [unique index](https://docs.mongodb.com/manual/core/index-unique/) on `id` and `email`.
!!! warning
**FastAPI Users** will use its defined [`id` UUID](../models.md) as unique identifier for the user, rather than the builtin MongoDB `_id`.
