Had the same issue a few weeks ago. Yahoo thought my account was hacked so they locked the account. I got the same errors till I logged into my account on my PC and changed the password.

Never had an issue with my iPad 3. So far I have been able to get one account running after changing password as suggested by iVegas. No luck with any additional account.
