Please, my people on Nairaland, I have been having challenges on using my Yahoo! email account. The login page says "Invalid ID or Password: Please try again using your full Yahoo! ID". I have done this many times. I have also used "I can't access my account" to get help and the system keeps showing "The security code you entered wasn't correct". I have tried different codes and it has not opened. A friend of mine noticed this some days ago and we thought it could be because he was using his phone to check his mails and it could be conflicting with his ID on laptop. Please if anyone has overcome this challenge recently, let him/her share the experience on how it was resolved.

I have been having the same problem. A good thing I switched to googlemail when I did
