Wordpress Fix

This is about WordPress development subject, I need a "User Center" to replace WooCommerce's "My Account" with single sign-on, separate domains, like Google does www.google.com; accounts.google.com; and myaccount.google.com. I hope my other websites can successfully call this user information to achieve single sign-on. But please don't use the SSO service of a third-party company, we need our own Mysql and CAS server. I hope you include enough APIs in your development so that you can continue to develop and call in the future. Regarding the expansion of the "User Center", this may be the second phase of work, so I hope you can take into account the future availability. If the first cooperation is pleasant, hope for long-term cooperation.
