check input against laravel5.1 generated password (bcrypt / hash / application key)

I'm using laravel5.1 in my main application, where users can register account etc. Now I need to authenticate users input (username and password) on a second server against the userdata I stored on my database server created by laravel. Checking username is easy, but is there an PHP function for bcrypt where I can put my laravel application token into, so I can check, if a password, entered by a user is the same password the user used to register through laravel?
