Not at all.  Any ISP doing a transparent proxy should be doing "IP
Spoofing" so that the connection still appears to come from the client IP
address. That's not to say that they all do, but...

That said, I would hope that the "authentication" is occurring over HTTPS,
and there's no reason any ISP should be running a transparent proxy for SSL
traffic.
