validations on a LiveView form), this option can be set to `false`.

Generates a token that will be stored in a signed place,

tokens do not need to be hashed.
The reason why we store session tokens in the database, even
though Phoenix already provides a session cookie, is because
Phoenix' default session cookies are not persisted, they are
simply signed and potentially encrypted. This means they are
valid indefinitely, unless you change the signing/encryption
salt.
Therefore, storing them allows individual user
sessions to be expired. The token system can also be extended
to store additional data, such as the device used for logging in.
You could then use this information to display all valid sessions

Handles mounting and authenticating the current_user in LiveViews.
## `on_mount` arguments
* `:mount_current_user` - Assigns current_user
to socket assigns based on user_token, or nil if
there's no user_token or no matching user.
* `:ensure_authenticated` - Authenticates the user from the session,
and assigns the current_user to socket assigns based
on user_token.
Redirects to login page if there's no logged user.
* `:redirect_if_user_is_authenticated` - Authenticates the user from the session.
Redirects to signed_in_path if there's a logged user.
## Examples
Use the `on_mount` lifecycle macro in LiveViews to mount or authenticate
the current_user:
defmodule ComfycampWeb.PageLive do
use ComfycampWeb, :live_view
on_mount {ComfycampWeb.UserAuth, :mount_current_user}
