Is it okay to list the projects I've worked on for a web agency for my portfolio website?

I'm currently planning my portfolio website and I'm wondering if it's cool to list out (+ screenshots of the website + details of the processes that went into developing it) a few agency projects that are mainly developed by my self and is created for public viewing? If not would it be ok to make the project listing page password-protected so that only the interviewers can view it?
