I also need an auth system that when someone registers or updates their account, it also updates in the different databases. first example logged into [login to view URL] It also starts automatically in [login to view URL] in [login to view URL] and in [login to view URL] and that when someone wants to close in any of those domains they close in all at the same time second example Someone registers or updates their account, the data goes to the different database 1 database2 and database3
