Why am I getting "Web Login Required" message while connecting to Gmail via IMAP?

Question

I'm trying to connect and retrieve a list of message headers from Gmail via IMAP.

I'm getting a response from Google with "Web Login Required" and then a URL to continue the sign-in via the web interface. Log: http://hastebin.com/odufaducew.vhdl

Why does this happen? How to handle this case? I'm using the MailCore2 lib for iOS if that helps at all.
