I have used the same PC every day for 3 years, yet I can't sign in without authorizing my device from another device. I do not use 2 layer authentication. It is turned off. I don't have cell service where I work, yet yahoo always asks to send a code to my cell phone. Makes it impossible for me to use Yahoo.
