IMPORTANT: Apps such as Email that support certicates

allow you to install certicates directly from within the app.

For details, see the Help or other instructions that come

with each app.

Work with CA certicates

If a certicate authority (CA) certicate gets compromised, or for

some other reason your organization doesn’t want to trust it, you

can disable or remove it. To do so, follow these steps:

1. Touch

Settings > Personal > Security > Credential stor-

age >Trusted credentials. The trusted credentials screen has

two tabs:

System displays certicate authority (CA) certicates that are

permanently installed in the ROM of your tablet.

User displays any CA certicates that you have installed your-

self, for example in the process of installing a client certicate.

2. To examine the details of CA certicate, touch its name.

A scrolling screen displays the details.

3. To remove or disable a CA certicate, scroll down to the bot-

tom of the details screen and touch either Disable for system

certicates or Remove for user certicates.

When you disable a system CA certicate, the button at the

bottom of its details screen changes to Enable, so you can

enable the certicate again if necessary. When you remove a

user-installed CA certicate, it is gone permanently and must

be re-installed if you want it back.

4. In the conrmation dialog that appears, click OK.
