Laravel 5.1 Middleware to check the creation date from a user to change password

I'm developing a webapp with Laravel 5.1 and I'm building the authentication system and I have to check if the user has not changed his password in six months or more and I would use a middleware to check this but I didn't find how I can do it properly. I created a global middleware but it is not working because I can't get the authenticated user.

It is possible that I have to use an AfterMiddleware to check the password?
