## 설명

WebFinger allows you to be discovered on the web using an identifier like `you@yourdomain.
com` — similar to how email works, but for your online identity.

**Why is this useful?**

 * **Fediverse & Mastodon:** WebFinger is essential for federation. It allows Mastodon
   and other ActivityPub-powered platforms to find and follow your WordPress site.
 * **Decentralized Identity:** People can look you up using your WordPress domain,
   making your site the canonical source for your online identity.
 * **Works with other plugins:** This plugin provides the foundation that other 
   plugins (like the ActivityPub plugin) build upon.

**How it works:**

When someone searches for `@you@yourdomain.com` on Mastodon or another federated
service, their server asks your WordPress site: “Who is this person?” WebFinger 
answers that question by providing information about you and links to your profiles.

**Technical details:**

WebFinger is an open standard ([RFC 7033](http://tools.ietf.org/html/rfc7033)) that
enables discovery of information about people and resources on the internet. It 
works by responding to requests at `/.well-known/webfinger` on your domain.

## 설치

### From WordPress.org (recommended)

 1. Go to **Plugins  Add New** in your WordPress admin
 2. Search for “webfinger”
 3. Click **Install Now**, then **Activate**
 4. Make sure pretty permalinks are enabled (**Settings  Permalinks** — select any 
    option except “Plain”)
 5. Visit **Tools  Site Health** to verify everything is working

### Manual Installation

 1. Download the plugin from [WordPress.org](https://wordpress.org/plugins/webfinger/)
    or [GitHub](https://github.com/pfefferle/wordpress-webfinger/releases)
 2. Upload the `webfinger` folder to `/wp-content/plugins/`
 3. Activate the plugin in **Plugins  Installed Plugins**
 4. Enable pretty permalinks if not already active
 5. Check **Tools  Site Health** to confirm the setup

## FAQ

### How do I customize my WebFinger identifier?

Go to **Users  Profile** in your WordPress admin and scroll down to the “WebFinger”
section. There you can set a custom identifier (the part before the @) and see all
your WebFinger aliases.

### How do I check if WebFinger is working?

Visit **Tools  Site Health** in your WordPress admin. The plugin adds checks that
verify your WebFinger endpoint is accessible and properly configured. If there are
any issues, you’ll see guidance on how to fix them.

### Does this work with Mastodon?

Yes! WebFinger is the standard that Mastodon and other Fediverse platforms use to
discover users. When someone searches for `@you@yourdomain.com`, WebFinger tells
them where to find your profile.

### Do I need pretty permalinks?

Yes. WebFinger requires pretty permalinks to be enabled. Go to **Settings  Permalinks**
and select any option other than “Plain”.

### For developers: How do I add custom data to the WebFinger response?

Use the `webfinger_data` filter to add your own links or properties:

    ```
    add_filter( 'webfinger_data', function( $data ) {
      $data['links'][] = array(
        'rel'  => 'http://example.com/rel/profile',
        'href' => 'http://example.com/profile',
        'type' => 'text/html',
      );
      return $data;
    } );
    ```

### For developers: How do I add alternate output formats?

Use the `webfinger_render` action to output custom formats (like XRD):

    ```
    add_action( 'webfinger_render', function( $webfinger ) {
      // Set custom headers and output your format
      // ...
      exit;
    }, 5 );
    ```

See [https://github.com/pfefferle/wordpress-webfinger-legacy](https://github.com/pfefferle/wordpress-webfinger-legacy)
for a complete example.

### Where can I learn more about WebFinger?

 * WebFinger specification: [RFC 7033](http://tools.ietf.org/html/rfc7033)
 * Community resources: [http://webfinger.net](http://webfinger.net)

 [Khürt Williams](https://profiles.wordpress.org/khurtwilliams/) 2023년 11월 11일

I installed Webfinger and typed in the domain for my website into Mastodon instance
photog.social. Mastodon immediately found ky ActivityPub endpoints.

### 󠀁[No config easy way to add webfinger for your existing users](https://wordpress.org/support/topic/no-config-easy-way-to-add-webfinger-for-your-existing-users/)󠁿

 [ffpf](https://profiles.wordpress.org/ffpf/) 2023년 1월 20일

Adding this plugin adds handling for the WebFinger protocol for your existing users.
For example, when someone searches for you on Mastodon, your server will be queried
for accounts using an endpoint that looks like this: GET ${MASTODON_DOMAIN}/.well-
known/webfinger?resource=acct:${MASTODON_USER}@${MASTODON_DOMAIN} So, if you have
a WordPress blog with the URL blog.domain and that blog has a user (you can see 
users in the Users admin panel) named user1, then the webfinger URL for that user
would be: blog.domain/.well-known/webfinger?resource=acct:user1@blog.domain This
plugin implements handling for such requests for any user on the WordPress site 
without any additional configuration.

There’s no admin panel and the documentation isn’t clear about how to configure 
the plugin.
