Comment(by dcf):

 Replying to [ticket:6986 dcf]:
 > 1. we can keep the master Gmail password offline, and only allow the
 facilitator access to IMAP under a different password. A breakin on the
 facilitator would not, for example, allow the intruder to set a new Gmail
 forwarding rule.

 I have tried setting this up, and now I'm not so sure that the
 application-specific password cannot be used to access the Google account.
 When I create the password, there is a notice:

   "Note that this password grants complete access to your Google Account."

 On the other hand, when I try to use that password to log in to Gmail with
 a web browser, it fails with the message

   "Please use your account password instead of an application-specific
 password."

 So I don't know exactly what the privileges are of this password. I think
 that having an application-specific password is good for security, even if
 it turns out to be root-equivalent and bypass SMS verification, because
 1. We can in the worst case completely delete the account using the master
 password, if the account is compromised.
 2. We can in theory detect when the application-specific password has been
 unauthorizedly used by examining the "recent activity" page in Gmail.
