 * Hello,
 * This is my scenario.
    I have several WordPress installations, which are all multisites
   in nature, which in turn form, WordPress Networks. Main installation is “parent.
   com”
 * Installation one is Africa, a multisite which is ‘parent.com/africa,’ and has‘
   parent.com/africa/site1,’ ‘parent.com/parent.africa/site2,’ ‘parent.com/africa/
   site3,’ ‘parent.com/africa/site4,’ and so on..
 * Installation Two is America, also a multisite which is ‘parent.com/america,’ 
   and has ‘parent.com/america/site1,’ ‘parent.com/america/site2,’ ‘parent.com/america/
   site3,’ ‘parent.com/america/site4,’ and so on..
 * Installation Three is Asia, also a multisite which is ‘parent.com/asia,’ ‘parent.
   com/asia/site1,’ ‘parent.com/asia/site2,’ ‘parent.com/asia/site3,’ ‘parent.com/
   asia/site4,’ and so on..
 * All main network sites, “**parent.com/africa**,” “**parent.com/america**,” and“**
   parent.com/asia**” are connected and being controlled from Parent Site; “**parent.
   com**” (theme, plugin and user management)
 * Now, on ‘user management’ is where I’m having a bit of a challenge.
    When a user
   visits “parent.com/america” or any of America’s child sites, they synchronized
   and do no need to login.
 * but when the same user visits jumps from ‘America’ to ‘Africa,’ they are no longer
   recognized. They have need to register, that’s when they can login.
 * I would like the user to be able to sign in, without multiple ‘registrations,’
   just as we do on ‘wordpress.org,’ ‘buddypress.org,’ ‘bbpress.org,’ and ‘wordcamp.
   org,’
 * Anyone know of free plugin that can synchronize users on separate WordPress installs??
 * Many Thanks..

 * [@prakharmonga](https://wordpress.org/support/users/prakharmonga/),
    I’m only
   controlling “network sites”
 * >  All main network sites, “parent.com/africa,” “parent.com/america,” and “parent.
   > com/asia” are connected and being controlled from Parent Site; “parent.com”(
   > theme, plugin and user management)
 * and I’m using this [plugin](https://wordpress.org/plugins/wp-multi-network/).
   I can easily install specific required plugins & themes for that specific network
   only, by accessing the “network site dashboard” from the “parent.com” site..
 * Now the challenge is, users..

 * The only method of sharing users is [CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE](https://codex.wordpress.org/Editing_wp-config.php)
   but the WP instances have to use the same database; but using different table
   prefix.
 * OP – If I had to do what you are doing, I would have tried to do it all under
   one WP multisite instance using the [WP Multi Network plugin](https://wordpress.org/plugins/wp-multi-network/)
