Mac | Back Up or Export Your Client Certificate

Solution ID : TL238
Last Modified : 07/24/2025

After you generate and install your Client Certificate, we recommend backing it up. The backup copy saves you from needing to generate a new certificate should you transfer to a new computer.

The backup copy also allows you to import your certificate into a Keychain or Certificate Store, should you want to use a different browser to log in to your DigiCert account. Client Certificates may be limited to a specific browser(s).

  • Mac installs the Client Certificate in its own Certificate Store and can be shared by the keychain for Safari and Chrome.
  • Firefox installs the Client Certificate in its own Certificate Store and can only be accessed by Firefox (Windows or Mac).
  • Windows installs the Client Certificate in its own Certificate Store and can be shared by Chrome and Internet Explorer.

After you have exported your Client Certificate with private key, you can import the certificate into a Keychain or other Certificate Stores so that you can log into your DigiCert account using another browser. See (Mac) Importing Your Client Certificate.
