So I am currently staying at a hotel and I don't have my mi-fi with me which is usually how I get on the Internet when I am away. After I connected to the hotels wifi I tried going to Facebook and I get a pop up that says "safari can't verify the identity of the website "www.facebook.com."" What does this mean? It says that the certificate is invalid and that I might be connecting to a website that is pretending to be "www.facebook.com", and also asks if I want to connect anyways. Is this safe? Am I being dooped? Sorry if this was a noobish question but I get concerned about the safety of my information
