Myself, and many others, have difficulties entering our auth codes before they expire. Could someone please confirm the expiration time limit for entering auth codes? They seem to be expired upon arrival in some instances; is this due to the expiration time being set so low that network delays will be a significant factor?

It seems as though there is only ~1-2 minutes of time before the code expires. Is this accurate? What should someone do if your emails are not getting sent quickly enough to be able to enter the code on time?
