You will be asked to confirm your security questions for a number of reasons. The questions are your guarantee that only you can access your Betfair account, and ensure that your details are secure and that no-one else can access your account.  
The most likely times you will be asked are:  

• When contacting Customer Servide via the phone or chat
• If you use the Forgotten Password option

If you have any issues resetting your password at the security question stage, please contact us by chat or telephone.

Please be aware that Betfair will never ask you for your password or security questions by email. If you have any queries over any email that is sent purporting to be from Betfair, please contact us.
