Why do I get a warning about an “untrusted certificate” at some hotspots?
Most commercial hotspots present a digital certificate as a way to establish their authenticity. Since a digital certificate can’t be faked, this prevents phony hotspots (known as evil twins) from posing as legitimate ones, and subsequently stealing your username, password and other sensitive data when someone inadvertently connects to them. Before Easy Wi-Fi automatically logs you in to a hotspot, it examines the digital certificate supplied by the hotspot and verifies that it has been signed by one of trusted certificate authority (CA) certificates. Your Nokia phone, however, may only have a limited set of trusted CA certificates. If your phone does not have a required CA certificate, then you will be prompted to accept the unknown certificate from the hotspot during the login process. This may reduce your ability to safely use a wide variety of public hotspots. In order to improve your security you can download and install a larger collection of trusted CA certificates from here.
