The first thing you have to do is check that the idCAT is in the browser's certificate store:
- With Internet Explorer : Go to Tools > Internet Options > Content > Certificates > Personal
- With Mozilla Firefox : Go to Tools - Settings - Privacy and Security - Certificates - Show certificates - Your certificates
- With Google Chrome : Go to Settings > Show advanced options > HTTPS/SSL > Manage 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
Check that your first name, surname and document number listed in the idCAT are the same as those appearing in your identification document.
Otherwise, you will have to go to an idCAT Registration Entity to request the revocation and reissuance of the certificate, as you will not be able to identify yourself with the public administration.
To confirm that your idCAT is working correctly, you can try to identify yourself on the website of a public administration or at the DEMO e-TRAM Testing Center (the procedures carried out have no legal validity).
In this regard, access the Generic Instance from the "Start" button and select the "Digital Certificate" option:
If you can access it correctly, your certificate is properly installed in the internet browser and is working properly.
