Overview

Using Launchpad, you can log into other websites and services that support OpenID. In OpenID terms, Launchpad is an OpenID provider.

Here's how it works:

  1. You visit a website that supports OpenID and it asks you to log in.

  2. Enter the Launchpad login URL - https://id.launchpad.net/

  3. If you're not already logged into Launchpad, it'll ask you to enter your username and password.
  4. Once you're successfully logged into Launchpad, it'll return you to the site you want to use.

Simple! This means that you only need to remember your Launchpad username and password in order to use websites that support OpenID.

There are a couple of things you need to know:

I've come across an error

If you encounter an error, it probably means that the site does not support OpenID 2.0.

To log in to these sites, visit your profile page and copy the URL from the "OpenID login:" field, then paste it into the OpenID Login prompt.

For example: https://id.launchpad.net/DDD/your_nickname

{i} Note: this id is case-sensitive.

How do I delegate my OpenID?

If you prefer, you can easily make a page on your website into your OpenID identity URL, while still using Launchpad as the underlying provider.

All your need to do is insert a snippet of markup between the <head> and </head> elements of one of your web pages: 

<link rel="openid.server" href="https://id.launchpad.net/" />
<link rel="openid.delegate" href="https://id.launchpad.net/DDD/your_nickname" />
<meta http-equiv="X-XRDS-Location" content="https://id.launchpad.net/DDD/your_nickname/+xrds" />

{i} Note: You'll need to replace the https://id.launchpad.net/DDD/your_nickname with your actual Launchpad OpenID.

Now, rather than presenting your Launchpad OpenID, you can enter your OpenID as http://mywebsite.com. When you show up as a commenter - on LiveJournal, for example - it'll display your web page as your OpenID. However, as Launchpad is still providing the back-end, you'll still need to log-in at Launchpad.
