[WPF-MVVM]] Double passwordbox

Bonjour à tous,

J'ai un souci avec mes Passwordbox en WPF en essayant de respecter le MVVM, j'arrive a le faire fonctionner sans souci pour ma vue de login, mais l'utilisateur à la possibilité de changer son mot de passe, donc il y a un Passwordbox , et un de confirmation.

Avec ce que j'utilise actuellement j'ai la possibilité de récupérer qu'un seul Passwordbox.

Code de ma vue:

Pour le moment je vais faire une vue intermédiaire, dans la vue ci dessus il n'y aura qu'un seul mot de passe, puis après validation, une seconde vue avec juste la confirmation du mot de passe.

Merci de votre aide
