Trusted Credentials
If a certificate authority (CA) certificate gets compromised or
for some other reason you do not trust it, you can disable or
remove it.
1. From the Home screen, tap
More ➔ Security.
2. 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.
3. Tap a CA certificate to examine its details.
A scrolling screen displays the details.
4. Scroll to the bottom of the details screen and tap Disable
to disable a System certificate or Remove to remove a
User certificate.
➔ Settings ➔
Caution! 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.
5. Tap OK to return to the certificate list.
When enabled, a check mark appears in the check box.
