Cannot Login to iCloud with 2-Factor Authentication

#1762

Hi :)
I just tried to add a new iCloud account to MailMate but it doesn't work.

The iCloud account was set up using 2-factor authentication.
I can log onto the account using terminal, Apple Mail etc, but MailMate doesn't connect.

I know there are messages on the IMAP server because I can see them using iCloud from a web browser.
I can also see them using Apple Mail.

In MailMate, the 'Synchronise' option is greyed out for the mailboxes for this account,
and no emails are downloaded when I select 'Sync All'.

I don't get any error messages when I try to sync.

The Activity Viewer displays :-

07:58:12 S: A0 NO [AUTHENTICATIONFAILED] Authentication failed
07:58:12 Error: Server response: “A0 NO [AUTHENTICATIONFAILED] Authentication failed”. Command attempted: “A0 AUTHENTICATE PLAIN ••••••••••”.
07:58:12 Retrieving password (keychain or user request)
07:58:12 C: A1 AUTHENTICATE PLAIN ••••••••••
07:58:12 Error code: 9
07:58:12 Failed action (1000). Reset observed read/write timeouts: 8/8

07:58:12 Handling reply

I know I'm using the correct password etc because I can log into the IMAP server using Terminal ...

Any suggestions ?

    Since Terminal is working then I'm probably not right, but I just need to make sure you are aware of application specific passwords.

    (It works in Apple Mail because Apple, and Apple only, has access to a different authentication method which does not need an application specific password.)
