Privacy & Security of this form This login is private and secure: the information you submit is encrypted, used only used to search for a matching customer account, and then discarded. Technically savvy users may wonder why this isn’t a true 2-factor login; it is a thoughtful design choice.?Security and convenience are diametrically opposed. The goal of the access system on is to have security that’s just casual enough that no one has to worry about saving a password, but of course still good enough to prevent most abuse. Technically this is a “single factor” authentication system — you just have to be able to identify yourself — which I believe to be adequate for our purposes here. The Google privacy popup in the lower-right is there only so I can use their “reCAPTCHA” service to prevent automated abuse of this form.
