You can now use your openid to log into your account. This feature might still be a bit buggy though. To enable your openid: login to your account -> profile -> openID identities (tab) -> add identity.

If you don't yet have an openid identity you can get one eg from myopenid.com. If you don't know what openid is you can get a detailed intro at openid.net. Basically it is a digital identity which allows you for example to use the same userid and password on every openid enabled site (which is nice).
