It's not hot news but I think it's useful info.OpenID provides you with an identity you can then re-use on several internet site. OpenIDFrance is the french site to achieve the same goal.
You can then use this identity by providing the URL that OpenId gave you when you register to the site you are visiting. The first time your login/password will be asked.
Thus, you can manage your information centrally and automatically fill forms with it.
Cherry on the cake. If you have a google account or others (see here) you already have an openID account.
