Mac OS Unable to add Yahoo to internet accounts

[Keith-f]

I had problems getting my mail via my mail accounts on my mac.

I tried removing my mail account from Mac OS and reinstalling. But when I try to add the yahoo account via 'internet accounts', I can enter my emaill address and password, I get the two factor code via my phone and enter that.

then i just get the message 'authentication failed'

This happens whether using the dedicated 'Yahoo" account set up or selescting 'other' and entering ther server details manually.

I can log in fine via safari on my mac and the accounts work fine on my ipad and iphone, but refuse to authenticate on Mac OS  (10.15.7).

Any ideas?
