It could be that because you have logged in to your account using your mobile devices that Yahoo believes your account has been compromised. I've had this happen to me also. You should follow the steps that Yahoo offers when having login problems.

Try clearing all caches and cookies and allow pop ups. Also Yahoo might not be able to log you on ecause you are already loggoed on on your mobile device. Try to log off there before changing anything on your computer. Hope this helps.
