OpenID is gaining popularity! Hyves is now also OpenId-provider, as published on the (Dutch) site Webwereld. This means you can use your hyve account to login to any site that provides OpenId. Saves remembering passwords. Unfortunatelly, you can't login to Hyves using another OpenId - Hyves is not a OpenId consumer. If Hyves would be an OpenId consumer you could login using for example your Hotmail account or Gmail account.
