I don't use yahoo, but I have had this issue in the past with Gmail. It was due to using two factor authentication, so if you have that (not sure if yahoo does) I recommend disabling it for at least now. There may be a better solution but I don't have one.

This happens frequently on my PlayBook, has happened once on my Z10, and never happened on my earlier BBOS BlackBerry models that were of course on BIS. I don't know the exact problem, but I see it (at least in my case) as a hiccup of sorts between the email client on the devices and the Yahoo system. It never happens with Windows Live, not even on the PlayBook.
I don't know what can be done.

Here is the answer to your problem. It drove me crazy trying to resolve until I found the answer.
This above link goes to: https://help.yahoo.com/kb/yahoo-account/SLN15241.h
With second sign-in verification with Yahoo, your device needs a special app password.
My only comment is to SAVE the password generated as inevitably you will have to retype it in whatever device may lose it and need it again. It is easier to save and retype than to do the above all over again, although it is easy enough to do.
Hope this helps. I even had to assign one for my PC because I automatically download all my Yahoo messages to my MS Office Outlook program on my PC and the second sign-in verification doesn't work with Outlook program unless you use the App Password. Works find again after all is done.
