Intercepting Filter pattern

I want to implement intercepting filter pattern in JAVA to find if the password entered is as per the requirement. For this I can create a filter class. But how do I handle the situation when password is incorrect, should I pass it to the target class or return false from filter class. I was following some online tutorial to authenticate request but in that they have not mentioned what to do when authentication fails. Also I don't think my understanding of target class is correct, for me the target class is something which is called after all the filters show that the request is authenticated.

Thanks
