If you have ever set up a wireless connection from home, you may have run across something asking for a WPA2 password. WPA2 is short for “Wi-Fi Protected Access 2.”

The WPA2 protocol was introduced in 2006, and many people use it to provide greater Wi-Fi security for their families. You can usually find your WPA2 password in your router’s security settings and will get asked for a new password when setting up your home network.

You may get tempted to skip adding a WPA2 password during your wireless setup because you fear forgetting a password. The problem is, using Wi-Fi without a password comes with the danger of someone else hacking into your network. Keep reading to learn why you need to use this protocol for your Wi-Fi network before accessing any internet sites, and how you can add even more Wi-Fi security with one of the best VPN apps.

What is a WPA2 password?

A WPA2 password is the second-generation protocol for Wi-Fi Protected Access. When you set up your home network system, you will create a Wi-Fi password in your router settings using this protocol.

You will not have to meet specific requirements for a WPA2 password. A general guideline for a strong password is to use at least 16 characters. That will make it harder for internet hackers to crack, which is the ultimate goal of having a WPA2 password.

We recommend you use a combination password to make it more secure. When using a combination password, ‌include upper and lowercase letters. You also want to use at least one special character and, at minimum, one number.

When it comes to choosing your WPA2 password, you don’t have to overthink it. Some people try to make it complicated and get frustrated in the process. Although you want a strong password, you also can think of some combinations that make sense to you. The sky's the limit because you can use any characters you choose. Have some fun with it until you find what works for you.

It is a good idea to use something that others would not guess. Never use your name or the name of a family pet. A strong combination password could be something like “ITexpert$et4life.” You can arrange the characters any way you want.

Alternatively, you can use one of our recommended password managers to create a WPA2 password for you.

The history of WPA2 security protocol

The WPA2 password security protocol was established in 2006 to prevent unauthorized users from accessing your home network. The WPA2 password protocol is still getting used 16 years later because it continues to provide security protection.

WPA is the security standard to make any wireless network safe. Before WPA, the gold standard was WEP but got replaced because of security vulnerabilities. The WPA protocol uses a 256-bit key for encryption, rather than the 64-bit and 128-bit used by the Wired Equivalent Privacy (WEP) protocol system.

For instance, on a 256-bit system, it would take a hacker approximately twice as long to decipher the password than it would to guess the password for a 128-bit system. The higher the number, the more possible combinations you have available.

The outdated WEP protocol was able to use the 64-bit encryption, which is the lowest protection standard now. Hackers could break into the network with more ease than they can now with the stronger encryption that WPA uses.

• WEP: WEP is the first network security protocol. This was the security standard in 1999 and claimed to offer the same security as a wired network connection.
• WPA: When the original WPA security protocol began, it was the first to accept human-friendly passwords and phrases. It also introduced the Temporal Key Integrity Protocol (TKIP). TKIP prevents attacks that were once possible on WEP networks.
• TKIP: TKIP made it possible to join other network connections without showing unauthorized users your secure information. That change was a definite improvement over WEP technology.

With WEP, everyone on the wireless network could share the same information. All users became vulnerable to anyone else who joined the same network. The traffic that flowed through it could get intercepted by another user nearby. That happens because the WEP protocol uses the same key that gets shared with everyone using the network. 

WPA technology made it possible to connect to a public network that uses the same password for everyone, and your traffic remained more private because of stronger encryption.

What is a WPA3 password?

The WPA3 password is the third generation of the security protocol developed by the Wi-Fi Alliance. It is the updated version of WPA2.

The Wi-Fi Protected Access 3 (WPA3) protocol is a newer security protocol designed to encrypt your data using an automatic and frequent encryption type. The encryption used is called Perfect Forward Secrecy.

The WPA3 security protocol may be considered more secure than the previous version, WPA2. It uses more robust data encryption. WPA3 guards against offline dictionary attacks that attempt to guess passwords by using Simultaneous Authentication of Equals (SAE) authentication.

One of the ways a WPA3 password keeps communication secure is with advanced encryption practices. For instance, when connecting devices, WPA3 security uses a 384-bit Hashed Message Authentication Mode. If a hacker picks up the communication between these devices, the unauthorized user cannot figure out the encryption key used for the connection.

WPA3 password security also won’t allow remote access. It uses near-field communication (NFC). That is a short-range technology that authenticates devices by tapping them together. For example, where WPA3 is used, you can take your smartphone and tap it against the WPA3 router and get instant network access.

Some may consider this a security issue because anyone within tapping distance can access the network. However, it also means that anyone not within tapping distance cannot access the network. Hackers cannot grab a remote NFC session.

Another feature you may like about WPA3 passwords is that your guests can access your network without a password. With a simple tap, they will enter the network without having to type anything into their devices. You must be using a device that supports NFC technology to use this function. Most smartphones can download apps to work with these.

Should you upgrade to WPA3?

When you want the most advanced network security available, the WPA3 is the ultimate system. It uses the most recent security standards on the market. WPA3 is also the fastest of the three WPA protocols.

If you wonder if you need to start using WPA3, you should consider your hardware devices. Some hardware may not support the more advanced features of WPA3. Whether you should go for WPA3 depends on the age of your hardware and how concerned you are about internet security. Because WPA3 security technology has only been around since 2018, some devices are not compatible with the newer protocol.

When you want the most advanced network security available, the WPA3 is the ultimate system. It uses the most recent security standards on the market. WPA3 is also the fastest of the three WPA protocols.

You will get a protected network by choosing WPA2 or WPA3. Both provide strong encryption to guard against hackers. WPA3 does come with upgrades that protect passwords from cyber attacks. Whether you should go for WPA3 depends on the age of your hardware and how concerned you are about internet security. Since WPA3 security technology has only been around since 2018, some devices are not compatible with the newer protocol.

Another point to consider regarding WPA3 is how often you will use public networks and if you will be allowing people to use your home network. If you use your internet for casual browsing, you will most likely be safe with WPA2.

Technology is constantly changing. There will always be new updates and upgrades to keep your network safer. You may find that you don’t need as much protection as someone who travels often or uses unsecured networks.
