How do I share logins with WordPress MultiSite? Please don't mark it duplicate cause I have never seen a post with Multi Site. I only see multiple sites. I have 5 multi-sites. I have a main site with domain.com. Login goes through accounts.domain.com/login. After logging in, they are redirected back to refer site. But the site again asks to login. I never got this issue when I was working as a super admin. I only realized this when I made a dummy account. Please help me.
