Alto

Alto lets you sign into websites using your domain name.

How to Use

Step 1: Add Alto to your website

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">

Step 2: Add a social profile or email address

You will also need to add a rel=me link. You can add links to any of the following profiles:

• Mastodon
• Tumblr
• GitHub
• Your email address

Here is an example:

<link rel="me"
    href="https://github.com/capjamesg">
<link rel="me"
    href="mailto:example@example.com">

Step 3: Use your domain name to sign in

When you sign into a service that supports web sign in, you will be able to log in using Alto.

Here are a few sites that support IndieAuth for sign in:

• Artemis, a calm web reader.
• The IndieWeb wiki, a community wiki for the IndieWeb community.
• IndieBookClub, a book tracking tool.
• webmention.io, a tool for accepting Webmentions.
• Telegraph, a tool for sending Webmentions.
