IndieAuth

IndieAuth is a way to allow users to use their own domain to sign into other websites and services.

It supports adding links to your WordPress posts, pages, and comments, indicating where a syndicated copy is, in the form of a text or icon link. You can do this 
manually or with supported plugins. Also contains a generic UI for syndicating to other sites through your site or a Micropub Client.
<h3>Privacy and Data Storage Information</h3>
This plugin stores syndication links, which can be attached to any post, page, or comment. They can be added to custom post types by filter.
For webmention initiated comments, this information will be added by parsing the source of the webmention. 
It is assumed if you send a webmention, you consent to share this information if it is publicly shared on your page. Our recommendation 
is that site owners should take down information on request.
For comments initiated on the site, there is built-in way to add these links. For posts, they are typically added by retrieving information stored by other plugins for display. It is assumed 
that by installing this plugin, as its intent is to display these links, that you wish to display them.
<h3>Settings</h3>
Settings for the Syndication Links plugin can be found in the main WordPress “Settings” tab in the 
admin dashboard, or if the <a href="https://wordpress.org/plugins/indieweb" rel="ugc">Indieweb plugin</a> is installed, under the Indieweb tab. The options provided allow for various ways of presenting the syndication links in posts. Syndication Links by default will add links to the content. You can remove this in your plugin if you wish to call the display function directly.
The settings include the following options as follows with either a set of buttons, a check box (with a check indicating that the feature is “on”) or an optional text field:
<ul>
<li>Display Text – Offers options to display text only, icons only, icons and text, and no display(hidden icons).</li>
<li>Size – Choice of small, medium, or large size icons.</li>
<li>Black Icons – Checking the box defaults to a “black” social media icon set.</li>
<li>Show on Front Page, Archive Page, and Search Results – If checked the icons will show on pages other than a single view. If not checked, the icons will be hidden by the links will remain.</li>
<li>Show on Feed – If checked the icons will show in your RSS feed as well</li>
<li>Text Before Links – This is the text that appears before the Display Text/Icons (as indicated above). The default text is “Syndicated to:” but can be modified if desired.</li>
</ul>
Note: The particular CSS of your theme may change the display and output of the text and some of the icons.
<h3>Supported POSSE plugins and implementations</h3>
The plugin supports automatically pulling data from plugins that syndicate your content so you don’t need to do it manually. For anything not built in, integation is easy with a simple filter for potential use with any other plugin.
<ul>

</ul>
Using the optional Syndication feature(disabled by default) you can syndicate your posts to:
<ul>
<li><a href="https://brid.gy" rel="nofollow ugc">Bridgy</a> – Bridgy is a service that allows you to post to various sites. Signup is required. It currently supports Github, Mastodon and Flickr. The plugin supports Bridgy Publish via Micropub by default.</li>
<li><a href="https://fed.brid.gy" rel="nofollow ugc">Bridgy Fed</a> – Bridgy Fed is a service that allows you to interact with federated social networks using webmentions.</li>
<li><a href="https://micro.blog" rel="nofollow ugc">Micro.blog</a> – Micro.blog is a social network and publishing platform for independent microblogs, created by Manton Reece. It uses a custom feed you can add to Micro.blog to support this.</li>
<li><a href="https://pinboard.in" rel="nofollow ugc">Pinboard</a> – Pinboard is a bookmarking site. The support for this is currently only enabled if you have Post Kinds enabled, due to the difficulty in getting a URL. It will bookmark the URL of any object you are citing.</li>
<li>Custom Webmention Syndication – Add any site that supports publishing by sending a webmention by configuring it in the settings page</li>
</ul>
Will be looking to integrate with other plugins to add more options and invite developers to add support if they wish as the interface is simple. 
The goal of the interface is not only can you syndicate via Micropub, but in the editor using a simple checkbox.

Syndication Links

This plugin is not perfect but is very useful and a great way of getting involved in the indieweb.

Get on board

Easy to use, works with Gutenberg!


It's convenient to have remote links all in the footer, where they're noticeable but not obtrusive, and marked up so that IndieWeb software will recognize them. Works great with both WordPress and ClassicPress.



I've had less success trying to auto-post through Bridgy, but that's at least partly on Bridgy's side.
