 As you can see, instantiation is quite simple. You just have to define a constant `SECRET` which is used to encode the token and the lifetime of the cookie (in seconds).

+* `cookie_path` (`/`): Cookie path.

 !!! tip
     The value of the cookie is actually a JWT. This authentication backend shares most of its logic with the [JWT](./jwt.md) one.
