Flickr (Yahoo) upcoming support for OpenID

According to Simon Willison, Flickr look set to support OpenID by allowing your photostream URL (eg. for me, to serve as an OpenID, ie. something you can type wherever you see “login using OpenID” and be bounced to Flickr/Yahoo to provide credentials instead of remembering yet another password. This is rather good news.

For the portability-minded, it’s worth remembering that OpenID lets you put markup in your own Web page to devolve to such services. So my main OpenID is “” , which is a document I control, on a domain that I own. In the HTML header I have the following markup:

<link rel="meta" type="application/rdf+xml" title="FOAF" href="" />
<link rel="openid.server" href="" />
<link rel="openid.delegate" href="" />

…which is enough to defer the details of being an OpenID provider to LiveJournal (thanks, LiveJournal!). Flickr are about to join the group of sites you can use in this way, it seems.

As an aside, this means that the security of our own websites becomes yet more important. Last summer, DreamHost (my webhosting provider) were compromised, and my own homepage was briefly decorated with viagra spam. Fortunately they didn’t touch seem to touch the OpenID markup, but you can see the risk. That’s the price of portability here. As Simon points out, we’ll probably all have several active OpenIDs, and there’s no need to host your own, just as there’s no need for people who want to publish online to buy and host their own domains or HTML sites.

The Flickr implementation, coupled with their existing API, means we could all offer things like “log into my personal site for family (or friends)” and defer buddylist – and FOAF – management to the well-designed Flickr site, assuming all your friends or family have Flickr accounts. Implementing this in a way that works with other providers (eg. LJ) is left as an excercise for the reader ;)
