When switching sites using the My Sites links in the admin menu, 
this plugin will automatically authenticate you into the site that you’re going to.
You do already have to be logged into a site in the network; 
this plugin just cuts down on having to log in again due to cookie isolation between domains.
Note: This plugin must be installed on all sites in a network in order to work properly.

Multisite Multidomain Single Sign On

Avoid having to separately sign in to separate-domain sites of the same multisite installation!

This plugin allows signing in users via JSON Web Token (JWT) in WordPress. It is used to allow users from another website/service/etc. to securely use their credentials for the WordPress site. 
Sample use case: There is an existing user database (e.g. in an intranet environment) and the users should be able to login to an external site that is powered by wordpress, without having to remember another password. This mechanism is also called Single Sign On (SSO). 
Please note that the user information and role mappings are updated each time the user logs in via SSO. If you do not want to sync the roles from your existing system to wordpress, you can disable the functionality via the settings page.
<h3>JWT Server</h3>
You will need to implement an endpoint on your website/app that has access to the logged 
in user (via login form or Kerberos-like authentication etc). That endpoint needs to create 
and sign a JWT with the HS256 algorithm and the below described information in the payload. 
It then has to redirect the user back to the WordPress site <code>https://example.org/?auth=jwt&code={jwt}</code> 
where <code>{jwt}</code> is the signed JWT as string representation.
