I enabled QRZ.com's 2-factor authentication because I had to in order to participate in the online "swapmeet," but frankly, it's getting to the point where it's not worth it. I regularly clear the cookies in my browsers, and often change computers to one with a different IP address, and when I do the site insists that I log in again. This entails getting a text message, pulling my phone out, transcribing a number, and then going on with what I should have been able to do in 30 seconds without so much hassles! Worse still, the numeric code only seems to be valid for a minute or two. If a text is delayed by the cellular provider, or if my text inbox is full and I have to clear out some old texts to receive the text from QRZ.com, the code becomes invalid before I can enter it. A good password is, frankly, security enough. 2-factor authentication schemes do nothing but complicate legitimate logins. Please consider revising the 2-factor authentication and/or simply allowing full use of the site with a good password.
