Public wifi is free but potentially dangerous
Have you heard stories like not being able to open PayPal, bank accounts, even emails when using public Wi-Fi ? So what are the real dangers of using public Wifi ?

Scammers often set up fake Wi-Fi networks in public places in hopes of stealing passwords and personal information. If connecting to a network like Free Wi-Fi, which doesn't require a password or welcome screen, can be a pitfall.
