I am new to Square and sent a "trial" payment link via email. A 2 factor authentication verifying a code from text message was required. I read this only happens if a transaction appears suspicious. I am wondering how often this happens. I am afraid the people I am sending my link to may not have access to text messages on the their computer, or will just be confused, and they will not be able to use link. Some of my recipients are not tech savvy. I was using Square to make collecting dues easier than people mailing check or give me cash, but I am concerned about possible tech, "glitches" that could be confusing to recipient. Please give me feedback
