Il existe de nombreuses façons de gérer la sécurité, l'authentification et l'autorisation.

Et c'est normalement un sujet complexe et « difficile ».

Dans de nombreux frameworks et systèmes, le simple fait de gérer la sécurité et l'authentification demande beaucoup d'efforts et de code (dans de nombreux cas, cela peut représenter 50 % ou plus de tout le code écrit).
