# `security`

Here's the reference for the authentication helpers provided by the `security` module.

You can import them directly from `fastapi_toolsets.security`:

```python
from fastapi_toolsets.security import (
    AuthSource,
    BearerTokenAuth,
    CookieAuth,
    APIKeyHeaderAuth,
    MultiAuth,
    oauth_build_authorization_redirect,
    oauth_decode_state,
    oauth_encode_state,
    oauth_fetch_userinfo,
    oauth_generate_state_token,
    oauth_resolve_provider_urls,
)
```
