just updated my new hAP ac2 to v6.48.7 earlier. i dont know if this problem came from this update or something else. For some weird reason, it will not take a new password for the admin. it just liked it blank !!!! So I created another admin user under group full. gave the user a tough password. Exited, came back, OK. Exited again, waited. Logged back in, and there you go, will not take the password. So I logged in as the default admin and it went through without a password. The ghost or a new bug!!
Anyone has the same issue?
