A new “Email Magic Link” button is added to the standard WordPress and WooCommerce login screens. If there is a user 
account for the username filled out, they will receive an email with a link to log them in without a password.
All emails sent from WordPress will contain login codes in links pointing back to the website:
<ul>
<li>Comment reply emails</li>
<li>Abandoned cart emails</li>
<li>Membership reminder emails</li>
<li>etc.</li>
</ul>
No configuration is required, by default:
<ul>
<li>Autologin URLs work for one week</li>
<li>Emails to administrators are excluded</li>
<li>Emails on exclusion shortlist are not modified</li>
</ul>
An API is available for developers to use autologin codes elsewhere in WordPress, e.g. push notifications, and to conditionally disable the plugin’s use. Code is published on GitHub, uses WordPress Plugin Boilerplate, conforms (mostly) to WordPress Coding Standards, and is unit & integration tested.

This plugin allows you to create many-to-many relationships between posts of any type: post, page, custom etc. A few example use cases:
<ul>
<li>manually curated lists of related posts</li>
<li>post series</li>
<li>products connected to retailers</li>
<li>etc.</li>
</ul>
Additionally, you can create many-to-many relationships between posts and users. So, you could also implement:
<ul>
<li>favorite posts of users</li>
<li>multiple authors per post</li>
<li>etc.</li>
</ul>

It works great. The options are beautiful, thought for every need, for example change a label or show only "to" box.

Works great

I'm working with WordPress, after some updates or actions the plugin starts to work incorrectly. The code is completely unreadable and can not be changed, the author abandoned his creation.
You can use - https://wordpress.org/plugins/npc-neatekpostconnect/

Huge load, unreadable code, Alternative for that plugin

Efficient many-to-many connections between posts, pages, custom post types, users.
