I would like to be able to know the creation date or last modification of my single-use verification codes in two steps in the Settings tab -> Security at https://accounts.firefox.com/. If it is not possible to know it, I would like it to be implemented, adding the date "created dd/mm/yyyy and hh:mm" in the same way that appears under Settings -> Profile -> Password. To know if the ones I have are the last created and I have not created others later, to be sure that I will not lose access to my account.
