In many cases, the security of WiFi passwords does tend to be overlooked. Often people prioritize stronger passwords for their online accounts over their WiFi networks. There are some reasons behind this.
The Lazy Factor: Default WiFi Passwords and convenience of remembering an easy password, thinking they are unimportant
Many people are too lazy to change the default passwords on their WiFi routers. Default passwords are often simple to guess or even publicly known.
Another reason why WiFi passwords may be less secure is the convenience factor. People often prefer easy-to-remember passwords for their WiFi networks because they don't want to go through the hassle of constantly entering a complex password on all their devices. This convenience can lead to the use of simpler and less secure passwords.
Also most people think, its very unlikely to be hacked, since an attacker needs to be in range in order to capture a handshake and to connect to the access point (AP).
Why attackers want your WiFi access? The underestimated risk
Although many owners think, they are not interesting or important enough in order to be hacked.
This is not the case, with access to your WiFi, an attacker gains a free, unrestricted AP without logs to engage in illegal activities like downloading copyrighted content, distributing malware, or conducting cybercrimes.
Also access to your AP makes it easier to intercept your internet traffic, potentially compromising your online privacy and capturing sensitive information, or even exploit vulnerabilities within your network, potentially compromising other connected devices or the network infrastructure itself, providing them lots of other possibilities.
Cracking WiFi password - Easier than assumed
WiFi passwords are actually much easier to crack compared to online passwords. Attackers can capture a handshake and then crack the WiFi password offline, without needing to stay within range of the network. In contrast, online passwords are typically attacked from anywhere, the risk of your account being compromised is significantly mitigated by the heightened competition among potential targets and they are also often better protected.
WiFi passwords are often less complex due to easily guessable default passwords and the convenience of easy-to-remember passwords. Also many people believe it is unlikely being hacked due to low WiFi range, and assume their AP does not provide a high value for an attacker.
