Spend only a couple of minutes on reading this article on MLWebTechnologies and forget about problems with data leak.
Is public Wi-Fi better than a mobile one?
Certainly! It offers free access to the network. Besides, you won’t have to pay for it.
However, this communications path is hardly protected, as a rule, and it doesn’t belong to you. To put it otherwise, Wi-Fi settings are unknown and you are to share it with other users.
Alas! Malefactors can be among these users around you. They target your data and know how to capture them.
Now we come to the wart. You’ll know about them only at the moment when they start using your data.
Don’t make this fatal error and use modern web technologies to interconnect Wi-Fi safely.
