place separate from your device. If you forget the code,

Certificate management
Digital certificates do not guarantee safety; they are used
to verify the origin of software.
In the certificate management main view, you can see a
list of authority certificates that are stored in your device.
Press to see a list of personal certificates, if available.
Digital certificates should be used if you want to connect
to an online bank or another site or remote server for
actions that involve transferring confidential information.
They should also be used if you want to reduce the risk of
viruses or other malicious software and be sure of the
authenticity of software when downloading and installing
software.
Important: Even if the use of certificates makes the
risks involved in remote connections and software
installation considerably smaller, they must be used
correctly in order to benefit from increased security. The
existence of a certificate does not offer any protection by
itself; the certificate manager must contain correct,
authentic, or trusted certificates for increased security to
be available. Certificates have a restricted lifetime. If
Expired certificate or Certificate not valid yet is shown
even if the certificate should be valid, check that the
current date and time in your device are correct.
