stored in your device. You receive notification if the
identity of the server is not authentic or if you do not
have the correct certificate in your device.
You can download a certificate from a web site, or
receive a certificate as a message. Certificates should
be used when you connect to an online bank or a
remote server to transfer confidential information.

Tip: When you add a new certificate, check its
authenticity.
