laravel authentication, create your own user?

Question

Laravel

is it possible to create a User extends Authenticatable (so that you can log in) and extends Model (I have this class associated with the rest using hasOne / hasMany)? so that these 2 classes are for inheritance, otherwise you have to create a separate User, which is needed for authentication and a second User, which contains fields with data and is associated with the rest of the tables in the database
