Locate the idCAT

The first thing you need to do is check that the idCAT is in the browser's certificate store:

  • With Mozilla Firefox : Go to Tools - Settings - Privacy and Security - Certificates - Show certificates - Your certificates
  • With Google Chrome : Go to Settings > Privacy & security > Security > Manage device certificates > Personal
  • With Safari : Open the "Finder" menu and type the word "keyboards", then the "keyboards" folder on your computer will open. In the subsection "My certificates" you can check if the certificate appears.
  • Microsoft Edge: Go to Settings > Privacy > Security > Manage Certificates > Certificates > Personal
