Code memo
Instead of having to remember all the different
security codes (for credit cards, etc.) you can save
them in the code memo in your phone. Then all you
need to remember is the password to open the code
memo. You can save a maximum of ten codes in the
code memo.
Checkword and security
To confirm that you have entered the correct
password for the code memo and to prevent
unauthorized access to your codes, you must enter a
checkword. When you enter your password to open
the code memo, the checkword is shown for a short
time. If the password is correct, the correct codes are
shown. If you enter the incorrect password,
the checkword and the codes that are shown are
also incorrect.
Factors strengthening the security of the Code memo
function are:
• You get no feedback about whether the password is
correct, except for the checkword, and only you
know the checkword.
• All codes are encrypted in the mobile phone.
• When you access your codes, they are shown for a
limited time only.
