Frequently Asked Questions

Common questions about IndieAuth

IndieAuth is a way for doing Web sign-in, where you use your own homepage or author post URL( usually /author/authorname ) to sign in to other places. It is built on top of OAuth 2.0, which is used by many websites.

IndieAuth is an extension to OAuth. If you are a developer, you have probably used OAuth to get access to APIs. As a user, if you have given an application access to your account on a service, you probably used OAuth. One advantage of IndieAuth is how easily it allows everyone's website to be their own OAuth Server without needing applications to register with each site.

IndieAuth was built on top of OAuth 2.0 and differs in that users and clients are represented by URLs. Clients can verify the identity of a user and obtain an OAuth 2.0 Bearer token that can be used to access user resources. You can read the specification for implementation details.

The goals of OpenID and Web Sign In are similar. Both encourage you to sign in to a website using your own domain name. However, OpenID has failed to gain wide adoption. Web sign-in prompts a user to enter a URL to sign on. Upon submission, it tries to discover the URL's authorization endpoint, and authenticate to that. If none is found, it falls back on other options. This plugin only supports searching an external site for an authorization endpoint, allowing you to log into one site with the credentials of another site if that site is listed as the website URL in your user profile.

Indieauth.com is the reference implementation of the IndieAuth Protocol. If you activate this plugin you do not need to use this site. IndieAuth.com uses rel-me links on your website to determine your identity for authentication, but this is not required to use this plugin which uses your WordPress login to verify your identity.

As of version 3.2, the endpoints return the display name, avatar, and URL from your user profile.

No. When you provide the URL of the WordPress site and authenticate to WordPress, it will return the URL of your author profile as your unique URL. Only one user may use the URL of the site itself. This setting is set in the plugin settings page, or if there is only a single user, it will default to them.

That, as mentioned, depends on the server. By default, the built-in IndieAuth server uses the WordPress login. By adding Indieauth support, you can log into sites simply by providing your URL.

We recommend your site uses HTTPS to ensure your credentials are not sent in cleartext. As of Version 4.5.5, this plugin requires Proof Key for Code Exchange(PKCE), whether or not the client supports it.

Once you have proven your identity, the token endpoint issues a token, which applications can use to authenticate as you to your site. You can manage and revoke tokens under User->Manage Tokens. You will only see tokens for the currently logged in user.
