If you have been using a PIN or the last four digits of your stored payment card to login on-line you can opt to Password protect your account as an additional security measure.
To add a Password to your account:
1) Once logged in, click 
in the top right corner of the page and select 
from the displayed dropdown options.
2) Enter the Password you wish to add to the account in the 'New Password' field then 'Confirm New Password' by typing again before clicking 
to instantly apply the changes.
Once added you will be required to use the Password you generated instead of the PIN or last four digits of your stored payment card when next logging in on-line or to the iPhone app. Android users will still need to use the PIN or last four digits of your stored payment card to login to the app even with Password protection.
