Does anyone know how to use a sites existing session user/pass login to, in order to login to phpbb3?

Everything I find talks about using phpbb3 as the primary login for a site. Thats not an option for me. I just want to insert phpbb3 and use my existing login

I haven't looked at the PHPBB code for a while (back in the 2 branch) but there is a file that controls logins.

Write a wrapper for the login function in phpbb3 and pass the username and password to both your site script and phpbb's script.

Though I wouldn't touch PHPBB's code with a 10-foot pole. I can't even understand it most of the time.
