I can't get yahoo to work with macbook air mail and a secondary security code

I can't get yahoo to work with macbook air mail and a secondary security code. Macbook air mail app keeps telling me it doesn't recognize this device please use secondary authentication, which I do both with phone number and email address and it just keeps bringing me back to the same page saying it doesn't recognize the device.

I have tried everything including deleting it and trying to re-install the yahoo account but I keep getting in this loop.

Does anyone at Mac or otherwise have a solution?

Thanks,

A
