Federated identity on Google App Engine

Question

I am successful with the both methods below, to log on using federated log in for my site on Google App Engine (Python)

users.create_login_url("\", "google", "https://www.google.com/accounts/o8/id")
users.create_login_url("\", "yahoo", "http://open.login.yahooapis.com/openid20/www.yahoo.com/xrds")

I wish to provide more log in options to my users. Can anyone help me with getting federated identity of Facebook, MySpace, Wordpress, etc..

Answer 1

Google documentation mentions following direct providers of federated identities ...

• google.com/accounts/o8/id (shorter alternative: gmail.com)
• yahoo.com
• myspace.com
• aol.com
• myopenid.com

... as well as username provider federated identities:

• flickr.com/USERNAME
• USERNAME.wordpress.com
• USERNAME.blogspot.com
• USERNAME.livejournal.com
• openid.aol.com/USERNAME
• USERNAME.myopenid.com
• www.myspace.com/USERNAME

Facebook is not an OpenID provider, forcing its own standard Facebook Connect.

Facebook started to accept OpenId a while ago: developers.facebook.com/blog/post/246 The linked article show how to achieve a user-friendly login with multiple providers. You basically create links to the services you want to support using users.create_login_url(federated_identity=...). – Brushwood

I think you can log into Facebook with OpenID but you cannot use Facebook account to log into for example stackoverflow.com. – Ventricose

Very thanks for the response dose google accepts microsoft live ids and in.com ids via open id i found some publishers using these two for open id, may be not on google frame work. – Pandanus

but what is the login url for facebook if we want to use it as open id provider – Cabaret

Answer 2

There is a partial list of OpenID providers on Wikipedia; Facebook is not an OpenID provider, preferring to make you use Facebook Connect. Myspace uses "myspace.com/username" as the federated identity, while wordpress uses "username.wordpress.com".

Here is an excellent resource for Open ID providers in the form of a nice JQuery plug-in: http://jvance.com/pages/JQueryOpenIDPlugin.xhtml

The OpenID site itself also provides a nice list of know providers: http://openid.net/get-an-openid/ – Lemur
