Wi-Fi devices follow a security protocol that makes it secure, which is to say that it will keep freeloaders that want to steal your internet out. The simplest way to explain this is that it creates a security protocol that only allows people with the key to gain access. For the time being, most home and personal use Wi-Fi distribution devices (such as routers) use the WPA2 (Wi-Fi Protected Access 2) security protocol, which has been in use since 2004.
Now, 14 years later, the Wi-Fi Alliance will begin to certify devices that follow the WPA3 protocols. For users, this won’t make a massive difference, since it will still follow a simple system of typing your Wi-Fi password and getting logged in. But the big differences here will affect hackers and anyone with malicious intent; typical password-breaking methods will be rendered useless by the new protocol.
Hackers will therefore have a harder time trying to get into your Wi-Fi. It’s specifically designed to protect against offline password guessing by attackers, and also block out older data on a Wi-Fi signal even if it happens to be compromised. All of this, as mentioned, is more advanced than what users need to be concerned about. As far as the lay user is concerned, your Wi-Fi is now more secure.

Actual adoption will take a while, since the Alliance is only now starting to certify products. At some point, you’ll be able to buy a new router that comes with WPA3 security, or if you’re lucky, your old router will be updated over the air to support the new protocol. Other companies, including Qualcomm, have already announced support, and will be rolling out a new chip for smartphones and tablets that will support the WPA3 protocol on the devices.
