Security questions are an additional level of security for customers who don't have a current account Visa debit card. They are required to use our Internet Banking service and must be enrolled for. Because only you know the answers to your security questions, they offer peace of mind when you carry out transactions on our Internet Bank
If you haven't been asked to enter a security question, don't worry. You will only be asked to answer a question if you're carrying out an activity you wouldn't normally do, so it could be some time before you have to do this.
Please remember that Nationwide will NEVER ask you for your security questions or answers over the phone or by email.
