The industry's latest promise to end Wi-Fi passwords is WPA3 : A protocol that allows access to securely authorized devices to a router. Something that can be very practical in our smartphones.
We all had to put a WiFi password sometime on our cell phone. It's the only way to connect to a Wi-Fi network, unless it's open and unsafe. This happens in our own homes, in the homes of our friends, in the bars and restaurants, in the hotels … and it happens so often that we are already accustomed.
But, even though it's getting used to it, it's still a nuisance to have to enter a password manually. There are tricks to trying to facilitate, like using NFC or QR codes, but it's still a nuisance. And this is something the protocol called WPS tried to solve, though not to much success.
WPS security flaws
WPS has never been very successful because, apart from being a complicated process, it is not safe. It has been advising, since 2013, the deactivation of WPS on compatible routers for this reason: even with a password and a secure protocol, the WPS served for to enter the router quickly and easily.
The reason for this is that WPS uses a PIN to connect between devices and the specification does not require much security. This enabled an attacker to test the 11,000 possible combinations for brute force obtaining access in a matter of hours . And so the best thing you could do was disable the router's function to prevent attacks.
WPS3, a solution with extra security
Because of all this, WiFi Alliance has released a new WPS standard. This would be the third version since the protocol was launched in 2006. And, to avoid all that we have just commented, puts much more emphasis on security .
As we can read in PCWorld WPA3 has individualized data encryption and includes measures for to prevent brute force attacks . In theory, the router may even warn you when someone tries to access by force. Although this probably depends on the router we have at home.
The best routers of quality / price "
The advantage to our devices is clear: we can forget to enter passwords long or confusing, without leaving aside security . With WPA3, it will be much easier to enter a Wi-Fi network and we will not make the network less secure.
The bad thing is we'll have to wait to see it working. Routers and devices are still missing the new standard. Once they are in operation, we can begin to see all these improvements in real life.
