Yahoo mail (ATT) (sbcglobal.net) requires password change after switching devices
I have used sbcglobal.net for decades - since I got it at a firm I worked at. It’s now ATT. It works fine on my iPhone. It works fine on my Mac. It works fine on my Windows 10 PC. But EVERY TIME I switch from the phone to a PC or Mac it tells me I have used the wrong password too often and directs me to change my password.
