web-sign-in: Difference between revisions

Revision as of 23:56, 3 June 2025

Use the (Web sign-in) button on a site to sign-in with your personal web address.

When you click a (Web sign-in) button, the site will ask you for your web address, e.g.:

Web address: [........................] (Sign-in)

or:

Web address:
[........................]
(Sign-in)

Enter your personal web address and press return / click (Sign-in).

set up

Your personal site must be set up for web sign-in.

Link from your personal site to your other profiles. Add rel="me" to those hyperlinks. E.g.:
<a rel="me" href="https://github.com/your_github_alias">...
Edit your other profiles, e.g. your GitHub profile, and set link (🔗) text field to your personal web address. E.g.
🔗 http://yoursite.example.com/
When you use your personal site with web sign-in the first time*, your browser will redirect you to to your online profile, e.g. GitHub, and ask you to:
- Sign-in with your account on that profile (e.g. sign in to GitHub) if you're not already signed-in.
- Authorize the site to use your account, e.g. your GitHub account:
  Authorize Site to use your account?

* Subsequent sign-ins to the same web sign-in form should be pre-filled with your domain name (e.g. via a cookie from the site) so all you have to do is click (Sign-in). In addition, if the site is properly using HTML5 <input type=url>, browsers will help you auto-complete your personal web address for you across all sites that do web sign-in.

user interface

For the Web sign-in UI, see the text mockups at the top of this page as a design starting point.

Important details:

The web address input "[........................]" MUST accept
- a "plain domain" e.g. tantek.com and canonicalize that to http://tantek.com/ or preferably to https://tantek.com/
- an http(s) domain without a path e.g. http://sixtwothree.org or https://sixtwothree.org and canonicalize http://sixtwothree.org/ or https://sixtwothree.org/ respectively

protocol

See the RelMeAuth page for documentation on how to support Web sign-in protocol on your site.

example implementations

RelMeAuth prototype demonstrates Web sign-in for both read-only/read-write permissions, and provides a simple interface for Tweeting when read-write permissions are provided.
IndieAuth not only uses Web sign-in but also provides a web sign-in authentication API!
- IndieWebCamp: Try out IndieAuth by signing-in to IndieWebCamp.com.
