I am trying to generate an app specific password, as I can not get Thunderbird on Ubuntu, to connect to the icloud server. I found a few posts on the web that infer, you now have to generate an app specific password, using the manage your apple id site. the instructions at the apple site say to log into your account
and click on the edit button in the security section, and then to click on "generate password". When I do this, no option appears to "generate password"
Steps outlined by Apple:
Sign in to your Apple ID account page.
In the Security section, click Edit.
Click Generate Password and follow the steps on your screen.

It appears that app specific passwords are not needed to access icloud on Ubuntu, using Thunderbird. I refired up an old box, I had stashed away; and, it connected to icloud fine, on Ubuntu using Thunderbird. I set up this account nearly 2 years ago and it works, with no app specific password. However, I never was able to set an app specific password at the apple site. So, I am closing this as, I don't actually need one.
