Digital certificates confirm ID and allow you to access restricted websites without having to type in a password etc. They are usully valid for a year and are then renewed.
My problem is that I now have 4 on my work P/C (insurance stuff) - one is current and three are expired certificates. When I log-on to an insurance site all 4 show up - rather than just the current one. Hence my question - so that I can remove the old ones from my P/C.
