Typically the 'forgot your password' button will then go to a screen for the user to enter the email address that's attached to the account and then the system will look up, from a server side database, the password attached to that email and then email the password to that email address.
You'ld have to know the structure of the user database and any associated usernames/passwords in place to access it, plus perhaps have an FTP account to get your code on to the hosting server.
If the owner of the website doesn't know any of this then you'll have to be authorized to talk to tech. support on his behalf to access, I'm assuming, PHPmyAdmin or some such program to query the database.
This post is based on my experience with SQL and PHP with my hosting service.
Hope this helps point you in the right direction!!!
