WiFi has become ubiquitous and is used in most homes — everything from mobiles to TV and even smart bulbs use WiFi. And, since the internet is vital to our daily lives, we often tend to share our home WiFi password with guests, among other people. However, there can be many security implications when it comes to sharing the password with everyone. So, let’s take a brief look into WiFi security and whether sharing your WiFi password is a good idea or not.
Hacking WiFi Passwords
Anyone can quickly attack your network with the Man in Middle or Identity Theft attack if they’ve got access to your network. Using these attacks, the hacker can steal your social media passwords, control the smart devices in your home. They can gain access to important information about your network and the devices.
Hacking WiFi is not a heavy task, even if you don’t share your WiFi with anyone. The hacker only needs to gain access to the WPA handshake, decrypting to hack your network easily.
You can use airmon-ng, airodump-ng, aireply-ng, aircrack-ng commands in the Kali Linux to gain access to the WPA handshake and brute force the network password.

The success of these attacks also depends on the wordlist that a hacker maintains. A wordlist is a list that has all the common passwords that usually people use, like “12345678” or “password”. Even if the hacker’s word list does not have your password, it won’t take much time for him to crack your password using various hacking methods available. After all, your password is just an alphanumeric string.
In your router settings, you will find something known as secondary SSID, using which you can create a secondary network. You can then use the secondary network to share with your friends and family or with smart devices. Thus, increasing the protection of your WiFi.
You can also hide your WiFi from the public; thus, it will be accessible by your devices only. However, some tools in Kali Linux can find hidden WiFi too.
The best practice, thus, would be not to share your WiFi password with everyone, and even if you do, share the secondary network so that your devices remain safe.
