This is a comparison guide between WPA2 vs WPA3. Wifi and Security have been getting bigger and bigger lately; with more devices coming to market that requires high-security standards.
One of the most popular methods for securing a Wifi connection is through the use of WPA2 – but it’s not perfect, as recent events have shown.
WPA3 (Wifi Protected Access 3) is now on the market and introduces some improvements that will help to make us all feel more secure and increase Wifi performance.
But is it really any better?
In this WPA2 vs WPA3 comparison guide, we’ll break it down, and you can decide!

What is WPA2?
WPA2 is the most widely used security standard for wireless networks today.
In fact, it’s the only one that has been officially sanctioned by the Wifi Alliance.
It is used to secure public access points in public places such as libraries, restaurants, and coffee shops – but it can also be used on networks at home and in offices.
WPA2 is a set of standards that were introduced in 2004, and there have been incremental improvements made since then.
When WPA2 was first introduced, it used an encryption protocol called TKIP (Temporal Key Integrity Protocol).
But this was quickly replaced by a more secure method called AES (Advanced Encryption Standard) in 2006.
In the early days of WPA2, there was some vulnerability reported in the protocols, leading to the use of Wifi Protected Setup, or WPS.
This system allowed customers to connect and secure their devices without ever entering a password.
There have also been other vulnerabilities reported, including one that allowed someone to decrypt a network even if they were only ever in the physical location of a router.
These vulnerabilities have been patched and fixed in succeeding updates, however.
What is WPA3?
WPA3 is a new standard in the Wifi world, and it’s set to be a big improvement on the old WPA2 methods.
It adds some extra security measures and functionality too.
It also allows for more flexibility, providing access to new features in your router that may have been previously reserved for advanced users.
The Wifi Alliance has said that there is no evidence that WPA2 itself is insecure, but they do advise customers to upgrade their router firmware when they can.
WPA3 has been designed to allow support for future versions, should they become necessary in the future.
It is backward compatible with WPA2 and earlier versions and will work on most modern routers.
WPA3 was introduced in 2018 and is now being used by the world’s largest ISPs and the biggest Wifi vendors.
It has an AES-256 key with a dynamic key management system (KMS).
It is designed to use 128-bit keys that are important in modern networks, and it uses AES-GCMP to generate encryption keys.
This completes a different dynamic key management system than WPA2.
What is the difference between WPA2 and WPA3?
There are definitely a few differences between the two, and some of them are certainly more noticeable than others.
We’ll debunk some of the myths, and explain how they work.
Encryption
WPA2 uses WPA-TKIP, which is a Temporal Key Integrity Protocol (TKIP), and it uses a master key only.
It is not encrypted or signed in any way.
This means that an attacker could easily intercept the key or crack its function.
Therefore, an attacker can decrypt any connection on the network with this method, even if they are not physically present in the area of the router.
WPA3 uses a modern and more sophisticated key algorithm, which is called the Simultaneous Authentication of Equals (SAE).
This protocol uses a private key to install a new and unique session key on every device, which provides superior encryption.
The main difference between WPA2 and WPA3 is that SAE uses the Extra Nonce method instead of the TKIP.
It also uses a more robust key exchange process.
Authentication
In WPA2, each device that connects to the network must create its own personal key.
This means that when a device is first connected to the network, it generates a key for itself and sends it to the access point (AP).
When a new device is connected, the AP downloads this key from the first device and starts using it for encryption.
WPA3 uses secure certificates, which allows each user to have their own unique session keys.
This enables all devices to negotiate their own keys.
It also uses a Protected Management Frames (PMF) to protect the data from being altered or snooped on by any attackers.
This protocol is known as Opportunistic Wireless Encryption (OWE), and it will help prevent the eavesdropping of frames on public networks.
Wireless Protocol
When it comes to WPA2, it works with an encryption technology called WPS (Wifi Protected Setup).
This protocol makes it easy for wireless devices to connect with protected Wifi networks without having to enter a long and complex passphrase.
WPA3 does not use WPS.
Instead, it uses the Password-Based Authenticated Key Management (P-AKM), which is an individualized and unique key for each device.
This makes it harder to hack into your network or access anything you don’t want them to see.
It also has a powerful system known as Device Provisioning Protocol (DVP), which can be used to automatically add new devices to your network using QR Codes or NFC tags.
Updating and Connectivity
WPA2 uses a relatively simple system for updating the access point firmware.
This is implemented through a process called a TKIP migration.
It can upgrade the firmware of older routers, even if they do not support WPA3.
However, this needs to be done when all wireless devices on the network support WPA3 or newer versions of it.
TKIP migration is not necessary for WPA3.
This means that it has a newer method to update router firmware and apply updates automatically.
WPA3 vs WPA2: Which one is better?
If you are looking to buy a new router, you might want to consider using WPA3 encryption instead of WPA2.
It offers a more secure and robust security system and uses modern and advanced technology in a way that will make your network more secure.
It is still completely compatible with most Wifi devices that are using the older WPA2 protocol.
With that being said, there are no plans to phase out devices that support only WPA2.
FAQs
Should you use WPA3?
Well, it is a good idea to consider using WPA3 encryption instead of WPA2, especially if you need to buy a new device in the future to support older devices.
WPA3 is the latest and most advanced security system supported by all newer wireless devices, but there are no plans to remove support for WPA2 soon.
