Why i can't open my yahoo account even i type the right email account and password?
Try accessing it from a desktop or laptop if you're on a device. The same thing happened to me, it said I was locked out for security purposes.
Someone may have hacked it do a forgot password and change it.
Is Caps Lock on? Maybe that's why...
Is caps lock on? Try clicking the "forgot password" button.And get a Gmail account - way better than Yahoo.
Because your computer may have pareolics it happend to me before
all i know is that is the hardest place to get into. i tried so many times i quit and havent been there for almost two years.
