This makes a change from the UK government’s approach of focussing on the use of ID cards as a means of control. In Estonia, every eID holder (around 80% of the Estonian population) has been given an unique OpenID . Their online identity can never be stolen because the OpenID is attached to their real identity: it is always possible to replace your stolen eID card and reclaim control of your identity.
