How To Use Trusted Credentials - Samsung Galaxy S4 Active

Learn how to use trusted credentials on your Samsung Galaxy S4 Active. If a certificate authority (CA) certificate gets compromised or for some other reason you do not trust it, you can disable or remove it.

  • From the Home screen, tap Apps icon > Settings > More > Security.

  • Tap Trusted credentials. The trusted credentials screen has two tabs:

  • System: Displays CA certificates that are permanently installed in the ROM of your device.

  • User: Displays any CA certificates that you installed, for example, in the process of installing a client certificate.

  • Tap a CA certificate to examine its details.
  • A scrolling screen displays the details.
    • Scroll to the bottom of the details screen and tap Disable to disable a System certificate or Remove to remove a User certificate.

    Note: When you disable a system CA certificate, the Disable button changes to Enable, so you can enable the certificate again, if necessary. When you remove a user-installed CA certificate, it is permanently deleted and must be re-installed, if needed.

    • Tap OK to return to the certificate list. When enabled, a check mark appears in the check box.

    Install from device storage

    Install encrypted certificates from an installed memory card.

    Note: You must have installed a memory card containing encrypted certificates to use this feature.

    • From the Home screen, tap Apps icon > Settings > More > Security.

    • Tap Install from device storage, then choose a certificate and follow the prompts to install.

    Clear credentials

    • Clear stored credentials.

    Note: This setting only appears if you have installed encrypted certificates.

    • From the Home screen, tap Apps icon > Settings > More > Security.

    • Tap Clear credentials to remove all certificates.
