Ever think about this that you’re sitting at home, watching YouTube or playing online games? You are connected to Wi-Fi, and everything appears to be perfect. But a question arises in mind: Is your Wi-Fi safe from any type of hacker? For the confirmation of these types of questions, then, security protocols like WPA2 and WPA3 come in. WPA2 and WPA3 are like invisible bodyguards that protect your internet connection. But here is a thing that will confuse: what is the difference between WPA2 and WPA3? And which one should you use? In this blog, we’ll find out about this in a fun and simple way.

What is WPA2?

WPA2 (Wi-Fi Protected Access 2) was first time back in 2004. WPA2 has been used for Wi-Fi security worldwide for many years. It uses strong encryption to protect data and is much safer than the earlier WPA and WEP protocols. As time passes and technology improves, hackers also find smarter ways to attack your data. So that’s why WPA3 was founded in 2018 as the next step in Wi-Fi security.

What is WPA3?

WPA3 is the latest and most advanced version of WPA2. It focuses on fixing WPA2 and WPA3 vulnerabilities and assists in making Wi-Fi connections safer for everyone. With more powerful WPA2 and WPA3 encryption strength, WPA3 makes it much harder for hackers to break into your network.

The Difference Between WPA2 and WPA3

Here are some main points that show the difference between WPA2 and WPA3:

Encryption Strength

The first difference is that WPA2 uses 128-bit encryption.
On the other hand, WPA3 uses 192-bit encryption, which is much stronger than WPA2.

Protection Against Password Guessing

In WPA2, if your Wi-Fi password is not strong (like “123456”), hackers can try to guess it using special software.
WPA3 makes this kind of attack much harder.

Public Wi-Fi Safety

In Public WiFi Safety, WPA2 doesn’t fully protect your data on open Wi-Fi like at airports or cafes.
WPA3 adds stronger protection, even without a password.

Device Connections

WPA3 uses a feature called SAE, abbreviated as Simultaneous Authentication of Equals, which makes it safer when devices connect.
WPA2 doesn’t have this feature.

WPA2 and WPA3 Advantages & Disadvantage

There are some benefits and some drawbacks of WPA2 and WPA3. These are available below:

WPA2 Advantages:

Advantages of WPA2 are

Firstly, it works with almost all devices (laptops, phones, smart TVs).
Secondly, it is still considered safe if you use a strong password.
Thirdly, WPA2 is stable and widely supported.

WPA2 Disadvantages:

The disadvantages of the WPA2 are:

Firstly, WPA2 is easier to hack if the password is weak.
Secondly, it doesn’t protect well on public Wi-Fi.
Thirdly, it is older technology with more known flaws.

WPA3 Advantages:

WPA3 advantages are:

Firstly, WPA3 is a stronger encryption for better security.
Secondly, it has better protection on public Wi-Fi networks.
Thirdly, WPA3 is harder for hackers to guess passwords.
Lastly, it is designed for modern smart devices.

WPA3 Disadvantages:

Disadvantages of WPA3 are:

Firstly, not all older devices support WPA3.
Secondly, the routers with WPA3 are often more expensive.
Thirdly, WPA3 may cause WPA2 and WPA3 compatibility issues when connecting older gadgets.

WPA2 and WPA3 Vulnerabilities

Both WPA2 and WPA3 assist you in protecting your data, but they still have some weaknesses. These are:

WPA2 Vulnerabilities: Hackers can use attacks like KRACK, which is a Key Reinstallation Attack, to steal your data. Weak passwords make it even easier to break.
WPA3 Vulnerabilities: While safer, researchers have found some flaws, like Dragonblood attacks. WPA3 is much harder to exploit compared to WPA2.

WPA2 and WPA3 Encryption Strength

Are you thinking of encryption as a secret code that hides your data? The more your code is, the harder it is for hackers to crack your password and data.

WPA2: good 128-bit encryption, but an older version.
WPA3: 192-bit encryption is a much stronger, future-proof, and updated version.

This means WPA3 provides better protection for the modern internet world.

WPA2 and WPA3 Compatibility Issues

There are some compatibility issues with WPA3. One of the biggest issues is that you can not connect all old devices to WPA3. Some older phones or laptops may not connect if your WiFi router supports only WPA3. To solve this, many routers allow a mixed mode, which allows both WPA2 and WPA3 devices to connect. However, this may slightly reduce security since WPA2 is weaker.

Which One Should You Choose?

Firstly, if you have new devices and a modern router, you must go for WPA3. It’s like upgrading from a bicycle lock to a bank vault.
Secondly, if you have an older device, then you must stick with WPA2, but always use a strong password.
Over time, WPA3 will become the standard, and WPA2 will slowly retire.

Conclusion

In the end, the main difference between WPA2 and WPA3 is like the difference between an old lock and a new digital lock. If you want to keep your WiFi safe, you must go for the WPA3.
