I am working on a web app where users submit their email in the invitation page. OAuth should only allow signups from approved users. Existing users can sign-in without any issues. I am currently using Google OAuth.
How can I achieve the above requirement?
Summary
Developers seeking to implement invite-only OAuth logins can achieve this by creating a whitelist of approved email addresses. By checking incoming sign-up requests against this whitelist, only approved users can create accounts through OAuth. Existing users can sign in as usual.
