Your site is unfriendly, my issue is that I'm ALWAYS asked to enter 6 digit code sent to my recovery email. I don't want to add my phone, and cookies are not saved. What's worst, when I tried to make a suggestion here: https://help.yahoo.com/kb/account?sclb=1, "Contact Us" is not working: "Support from a Yahoo specialist is not available."
As a user I'm tired and will move most of my stuff to google or microsoft. I do want a simple mail with username / password to get in, I need to DISABLE any double secure authentification.
