Eddie login process can reveal our VPN service provider so an ISP firm at least can determine which customer uses which VPN service. If a AirVPN customer don't want to be known by an ISP, mostly uses VPN over ToR to conceal its real IP from VPN server and also conceal its VNP server IP & service provider name from ISP company. Thus an ISP can't expose neither VPN server IP that you connect to at the first hop nor VPN service provider name.
That's why I'm using Eddie client to make VPN over ToR but client primarily requires log in with AirVPN account of users. This log in process basically posts your password & username to a server on the Internet. Eddie post mine to 18.104.22.168 (amazonaws.com). If ISP contacts to Amazon may reveal the VPN service provider.
Why Eddie client doesn't post these data over ToR, if user configure Proxy/Tor section? Eddie doesn't use TOR and post these data with our real IP. It doesn't make sense.
