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.
