Integration

The integration of the digital certificate depends on the operating system and software used.

As soon as you use software that uses the Windows certificate store, you must import your digital certificate into this central certificate store:

  • Start → Internet Options (type) → Map: Contents
  • Certificates → “My Certificates” tab → Import…
    • At the password prompt, enter the password you chose when the certificate was issued.
    • In the import options, do not activate the field “Mark key as exportable”.

Software under Microsoft Windows that uses the central certificate store are Google Chrome , Microsoft Edge / Outlook.
