Solution ID : TL237
Last Modified : 07/23/2025

After you generate your Client Certificate, we recommend that you open up your keychain or browser(s) that you intend to use and verify that the Certificate is installed in the appropriate keychain or Certificate Store.


How to Verify that Your Client Certificate Is Installed

Safari
Chrome
Firefox


Safari | Verifying that Your Client Certificate Is Installed

  1. Open Keychain Access.

    In the Finder window, under Favorites, click Applications, click Utilities, and then click Keychain Access.

  2. In the Keychain Access window, under Keychains, click Login, under Category, click Certificates, and you should see your Client Certificate if your certificate was installed in your keychain.

    If the certificate is in the Keychain, you should be able to use Safari or Chrome to log into your DigiCert account.

  3. If you receive the “This certificate was signed by an unknown authority” warning message, do one of the following things:

    • Ignore the message.

      The reason that you are receiving this message is that the Intermediate Certificate was not included in the Certificate Chain.

      The certificate was signed by DigiCert, and this message will not prevent you from logging into your DigiCert account.

    • Remove the message.

      If you want to remove the warning message, all you need to do is install the Intermediate Certificate, as follows:

      4. After Safari downloads the Intermediate Certificate, double-click the certificate to open it and install it in your login keychain.
