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.
-
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.
