Password directed to certain page

IS there a way to write code so that I could have a client log-in page that when a specefic password it is entered it goes to a specefic hidden page on my website. Example: Client A receives daily communication via the website. Client A enters their specefic username and password and it goes to client A’s page. Client B, Client C Client D etc would all have the same thing. None of them would be able to access each others pages.
thanks for your thoughts
