Google, IBM, Yahoo, Microsoft and VeriSing are five of the most powerful and famous tech companies at the moment, so the fact that they have all joined the OpenID Foundation Board make’s the organization’s dream more likely to come true. The five companies are expected to help OpenID Foundation Board build a single-sign-on service for the Web, according to the foundation’s Thursday statement.

The five tough companies’ addition to the project is highly important for the upstart organization that has been charged with promoting the work of the OpenID community, which is represented by many developers and companies. OpenID community’s main goal is to create the technology that would allow people create single identity for signing on to any web site they want without having to create separate accounts. Practically, OpenID’s project’s idea is to relieve people of the need to remember and manage a wide number of IDs and passwords.

But, although the mechanism promoted by OpenID sounds great for Web surfers, the organization’s proponents haven’t convinced many web sites to accept the new system. Still, the fact that Google and Yahoo!, IBM and Microsoft eventually said “Yes” might make the others change their mind.

Founded in 2006, the OpenID Foundation said in a recent statement that the addition of the new members and the resources they brought along will help the organization to “better serve the needs of the entire OpenID community.”
