Why is using a public Wi-Fi dangerous and how to protect yourself?

The Wi-Fi hotspot at the airport, at your university, the library, or your favorite coffee shop might be dangerous, compromised, or even malicious. It’s because most of these are public connections, and the keyword describing a public Wi-Fi is definitely “unsafe”. This means that if you are accessing, receiving, or sending sensitive information, the same information might be accessed by someone else.
