 * Recoverable: takes care of reseting the user password and send reset instructions.
+* Rememberable: manages generating and clearing token for remember the user from a saved cookie.
 * Validatable: creates all needed validations for email and password. It's totally optional, so you're able to to customize validations by yourself.

+    #   User.find(1).remember_me!  # regenerating the token
+    #   User.find(1).forget_me!    # clearing the token
