Not authorised message when trying to get into my Macair Yahoo mail account

[wandering+dream]

I have a longstanding Sky/Yahoo email account on my Apple MacAir laptop.   I returned to Sky a week ago and had to set up a new password etc but now, I am unable to get mail on my laptop.   Iphone, Web access to Yahoo is fine but, when I try to get into the mail on my laptop, I am asked to put in my password, when I do, 2 step authentification pops up, I put in the code then it comes up 'not authorised'.   I have tried the old password but that does not work either.   I have phoned Sky, but they can't help either.   Has anyone else had this problem and resolved it?

To repeat - password works on the web, my phone and to access Sky but...not on my laptop.

Are you trying to login to the Sky website on your laptop ?

When the 2FA asks for a code, are you receiving that on your phone?

You say it works on the web, so just how are you trying to access your email on the laptop?
