Alto

Alto lets you verify your identity using your domain name.

To get started, add the following meta tags to the head tag on your website:

<link rel="authorization_endpoint"
    href="https://alto.jamesg.blog/auth">

<link rel="token_endpoint"
    href="https://alto.jamesg.blog/token">

You will also need to add a rel=me link that is either an email or GitHub link, like:

<link rel="me"
    href="mailto:example@example.com">

When you sign into a service that supports web sign in (i.e. the Artemis web reader), you will be able to log in using Alto.
