You'll need to set a Security Question & Answer in your account in order for us to offer certain features to you. In order to do this, follow the below steps:
If you've previously set a Security Question and an Answer, you'll be informed contextually by an alert telling you that your security question is enabled. If you see this, then everything is working correctly.
We can't show you your previous answer as it's encrypted, so you'll be updating your existing answer here.
