This issue is resolved now, and Horizon should work as usual. Sorry for
the interruption!

Good morning!
As a side-effect of our response to the current gerrit vandalism
epidemic, the 2fa integration between Horizon and Wikitech has been
disabled. That means that existing Horizon sessions are still valid
but fresh logins will fail.
This problem is being actively worked on. In the meantime, don't
panic if you get an error while trying to log in.
