Issues with Yahoo Mail

Ever since I made the switch to Windows 10 at home—even though I've been a loyal Chrome user forever—I’ve run into this annoying little hiccup whenever I try to log into my Yahoo mail. It isn't even a matter of typing in my password anymore; instead, I have to grab my phone or tablet and manually approve the login request just to prove it's actually me sitting at the computer. It’s a bit of a hassle, really. Just about a month ago, back when I was still running Windows XP, Chrome would just remember my credentials without any of these extra hoops to jump through.
Does anyone have any thoughts on what might be causing this or how I can fix it?

It looks like you manually set it up to require identity verification whenever you log in from a new device. You should probably dig through your email settings to double-check that; I can't tell you exactly where it's buried since I've never actually used that specific service myself.
