I have a two part issue.
First, I did not authorize the new multi-factor authentication protocol that has recently shown up. I keep my accounts separate for a reason, so forcing me to access another one to get into this one constitutes a security violation and potentially opens the door to privacy issues.
Second, in looking at the "settings" option for a way to fix this problem, I find that there are virtually no settings available to review. You should be as ashamed of yourselves as I am of you.
