<p><strong><a href="http://developer.yahoo.net/blog/archives/2009/12/yahoo_openid_now_with_attribute_exchange.html?utm_source=feedburner&amp;utm_medium=feed&amp;utm_campaign=Feed%3A YDNBlog %28Yahoo%21 Developer Network Blog%29">Yahoo! OpenID: Now with Attribute Exchange!</a></strong></p> The nice thing about this is that an e-mail address obtained from Yahoo! via attribute exchange has already been verified, so you don’t need to perform the e-mail roundtrip yourself. I expect a lot of OpenID consuming sites will end up with internal whitelists of OpenID providers who they trust to provide verified e-mail addresses, with users of sites not on the whitelist still getting e-mailed a verification link. <p>Tags: <a href="https://simonwillison.net/tags/attributeexchange">attributeexchange</a>, <a href="https://simonwillison.net/tags/email">email</a>, <a href="https://simonwillison.net/tags/openid">openid</a>, <a href="https://simonwillison.net/tags/verification">verification</a>, <a href="https://simonwillison.net/tags/yahoo">yahoo</a></p>
