MySpace will join the OpenID alliance to begin letting its users take their online identity to other sites and social networks without having to register again.
The move comes after the network decided in May to let its users globally share their MySpace profile information on some other sites.
OpenID is an open source alliance that, by letting users take one identity to multiple websites, aims to eliminate the need to create multiple user names and profiles.
This would allow MySpace users to have MySpace accounts even when they're not on MySpace. However, members of MySpace will not be able to use their MySpace OpenID log into a site like Yahoo, which is also an OpenID member, or vice versa as both are considered "providers" and not "relying parties."
Providers can create new OpenIDs. Relying parties can accept OpenID members from other sites.
OpenID has already been embraced by any sites, including Yahoo, Plaxo, Wetpaint, Technorati, and LiveJournal.
