## Presentation

LL::NG Null backend is a transparent backend:

- Authentication: will create session without prompting any credentials (but will register client IP and creation date)
- Users: will not collect any data (but you can still register environment variables in session)
- Password: will not change any password

You can use Null backend to bypass some authentication process steps.

## Configuration

In Manager, go in `General Parameters` > `Authentication modules` and choose Null for authentication, users or password module.

Then, go in `Null parameters`:

- Authentication level: authentication level for this module.
