Thanks for your suggestions, folks. Tuvok, not sure what that App/password thing is all about, but will check it out later. This is the second time that this Yahoo mail issue has happened with my desktop p.c. - and the last time, we switched to Edge for emails and it seemed to work. And then shortly after we switched to Edge, it came back to normal on Chrome. Thankfully, I've got other devices to access Yahoo mail on, but really appreciate your advice everyone. Cheers, Chox.
