With OpenID SeatBelt plugin (developed by VeriSign) you can now manage your OpenID identities and delegations right inside Firefox. This plugin automatically fills-in OpenID input fields on websites and blogs that support OpenID authentication. It also enables fast identity provider (IdP) switching and protects against OpenID phishing attempts.
In one of the future posts I will explain how to add a SeatBelt configuration file to phpMyID single indentity provider software so that it can be used with your privately installed OpenID.
