What if I see a message about having the wrong credentials?
This usually means that the password or the email address has been entered incorrectly. Be sure that you have setup an "app-specific password" on the webmail server settings of the email account if you have enabled the 2 factor authentication or if you require such a password to access IMAP (for example -Fastmail accounts need an app specific password even if you do not have the two-step authentication enabled).
