I am trying to access webmail via CPanel and get this error "Authentication Failed"
using the following url https://id.cpanel.net/authorize/login. I can get in using the normal webmail url, but I want to set up my emails in Thunderbird please.
Additional System Details

I have no idea why you are referencing a cpanel login to use a mail client.
Your hosting provider will be able to advise you on the correct servers to use to use a mail client.
