Change password
The Change password feature allows you to change your current
phone password to a new one. You must enter the current
password before you can specify a new one.

of a password feature.
Once you enter a new password, you are asked to confirm it by
entering it again.

in a safe place. If you forget your password, your phone will
require service to have it unlocked.

your PIN each time you switch on the phone. Consequently, any
person who does not have your PIN cannot use your phone
without your approval.
