Authentication backends and helpers for Starlette-based apps and frameworks.

**Note**: documentation is in progress — in the meantime, feel free to read the source code!

## Installation

```bash
pip install starlette-auth-toolkit
```

**Note**: you need to [install Starlette](https://www.starlette.io/#installation) yourself.

## Base backends

Base backends implement an **authentication flow**, but **the exact implementation of credentials verification is left up to you**. You can choose to perform a database query, use environment variables or private files, etc.

Base backends are user model agnostic, although we recommend you use a subclass of `starlette.authentication.BaseUser`.

The documentation below lists which [scopes](https://www.starlette.io/authentication/#authcredentials) each backend grants when authentication succeeds.

Please refer to the [Starlette authentication documentation](https://www.starlette.io/authentication/) for more information on Starlette's authentication and permissions interface.

### [Basic auth](https://tools.ietf.org/html/rfc7617)

**Abstract methods**

- `.verify(self, username: str, password: str) -> Optional[BaseUser]`

  If `username` and `password` are valid, return the corresponding user. Otherwise, return `None`.

**Scopes**

- `authenticated`

**Example**

```python
# myapp/auth.py
from starlette.authentication import SimpleUser  # or a custom user model
from starlette_auth_toolkit.backends import BaseBasicAuthBackend

class BasicAuthBackend(BaseBasicAuthBackend):
    async def verify(self, username: str, password: str):
        # TODO: you'd probably want to make a DB call here.
        if (username, password) != ("guido", "s3kr3t"):
            return None
        return SimpleUser(username)
```
