<div>Yes - native non-browser Flickr applications like iPhoto and the Flickr Uploadr can be authorized using Google's OpenID service!</div><div><br></div><div>One of the interesting things about Flickr is that due to Yahoo's security policies, the Flickr service never had access to the user's Yahoo password. In order to get around this issue, Flickr had to develop a browser based auth scheme, so Flickr clients have always had to pop open a browser for the user to authorize access. Because Flickr clients have always had to open a browser for authorization, it was possible to add OpenID support for existing clients without forcing clients to be upgraded.</div>
<div><br></div><div>It is possible to support OpenIDs in general, however we had a business requirement to get the user's verified email address when logging in. The email address is necessary in order to send notifications to the user and also for the user to identify themselves out of band (such as when telephoning/emailing customer care). We were also hoping to use the email address to determine if the user already had a Flickr account and to automatically log them into their existing account, however due to lots of messy edge cases we decided to defer account linking until after we've proven the effectiveness of OpenID logins.</div>
<div><br></div><div>Given that we had a business requirement to get the user's verified email address, it's not really feasible to let a new user login with OpenID, then force the user to manually verify their email before continuing. The user probably would be better off registering a traditional YahooID instead.</div>
