Halifax@helpdesk.co.uk Subject: Existing Halifax customer Update Date: Sun, Dec 14, 2014 08:20 AM Dear customer, Starting from tomorrow, 15/12/2014 we are introducing new online banking authentication procedures in order to protect the private information of all online banking users. You are required to confirm your online banking details with us as you will not be able to have access to your accounts until this has been done. As you're already registered for online banking all you need to do is to proceed securely below. Internet Banking Verification. Once you've completed this you'll be able to manage your money whenever you want, giving you more control of your finances. Best wishes, Security Team. Halifax Banking Services.
