My security code isn’t being accepted

  • When you’re inputting your six digit security code, it’s best to type it in instead of copying and pasting it.
  • If you’ve gone back in the journey, to try again, then you might be putting the original code in, when the system is looking for the new one. Please wait a couple of minutes for a new code to come through and try again.
