Everyone is familiar with the situation of urgently needing internet access but running out of mobile data. At such moments, it's tempting to connect to a neighbor's hotspot without permission, using various apps or utilities. However, it's important to set boundaries right away: hacking someone else's WiFi is an illegal action that violates the rights of network owners and computer security laws.
Modern encryption protocols, such as WPA3, make password cracking virtually impossible for the average user without specialized equipment. Instead of searching for holes in someone else's security, it's wiser to focus on restoring access to your own forgotten keys or guest networks to which you were officially granted access earlier.
In this article, we'll explore the technical aspects of wireless network security, explain why popular apps from stores don't work as promised, and provide instructions on how to legally recover passwords on devices. Android And iOS.
Why can't I just connect to someone else's WiFi?
Many users mistakenly believe that having a smartphone and a special app gives them the magical ability to open any closed door in the digital space. In reality, architecture WPA2/WPA3 protocol The system is designed so that the handshake (the process of shaking hands between the device and the router) occurs using complex mathematical algorithms. Without knowledge of the original key, decrypting this data exchange in real time is impossible.
⚠️ Warning: Using brute-force attack software on networks you don't own is a violation of the law on unauthorized access to computer information.
Apps you can find in official stores Google Play or App StoreHacking-enabled apps are most often either marketing ploys or security analysis tools. They may show a list of available networks and signal strength, but nothing more. Operating systems Mobile devices have strict restrictions (sandboxing) that prevent applications from interfering with the network interface at such a deep level.
There's a myth about so-called "backdoors" or WPS vulnerabilities that allow you to bypass protection. Indeed, in older router models, the function WPS (Wi-Fi Protected Setup) could have vulnerabilities that allowed PIN recovery. However, modern routers either disable this feature by default or are equipped with PIN brute-force protection, making this method impractical for most modern networks.
Analysis of popular hacking apps
If you decide to explore the market for apps promising a "magic key," you'll encounter three main categories of software. Understanding how they work will help you avoid installing malware on your phone.
- 📡 Network scanners: These applications (eg Fing or WiFi Analyzer) are really useful. They display technical information: channel, channel width, encryption type, and airtime congestion. They don't know passwords, but they do help you choose the best location to install your router.
- 🗝️ Common password databases: Apps like WiFi Map They work like a social network. Users share passwords for cafes, hotels, or their public networks. There's no hacking involved, just data crowdsourcing. If your neighbor hasn't shared their password in the app, you won't see it.
- 🤖 Hacking simulators: Programs with names like "WiFi Hacker Prank" show a number-crunching animation, create the appearance of active work, but ultimately produce a random string of characters or simply do nothing. Their purpose is to display ads or collect user data.
⚠️ Warning: Downloading "hack" APK files from third-party websites often results in your smartphone being infected with Trojans that steal banking information and social media passwords.
It is important to differentiate between tools for security audit and tools for stealing access. Professional tools such as Aircrack-ng, require root access, an external WiFi adapter with monitor mode support, and a thorough knowledge of Linux. On a regular smartphone, launching a full-fledged network handshake attack without additional equipment is impossible.
Why do apps require strange permissions?
Many apps request access to geolocation, contacts, and the microphone under the guise of "improving network performance." In reality, precise location (GPS) is required by Android and iOS to scan WiFi networks, as the systems determine the device's coordinates based on nearby access points. However, access to contacts or SMS is completely unnecessary for a WiFi analyzer to function and indicates an attempt to collect personal information.
How to find your WiFi password on Android
If you've forgotten your network password, but you have an Android smartphone that's already connected to it (or was previously connected), recovering the access key is quite simple. Starting with version Android 10, the system allows you to view saved passwords without having to obtain root rights.
To do this, you need to go to the device settings. The path may vary slightly depending on the manufacturer's operating system, but the general logic is the same. You need to find the section responsible for connections.

Shareor an icon QR codeThe system will ask you to verify your identity using a fingerprint, Face ID, or pattern. Once verified, a square code will appear on the screen, followed by a text string containing the network password. You can copy this text or simply rewrite it.On some smartphone models, for example, Xiaomi or Samsung, the password may be hidden behind asterisks even in the menu. In this case, you can take a screenshot of the QR code and recognize it using any service (for example, Google Lens (or a built-in image analyzer), which will output a hidden connection string including a password.

Device owners Apple For a long time we were unable to view our saved passwords, but with the release iOS 16 This feature is finally here. The process is now identical to Android and doesn't require installing third-party software.
To see the key, open

Simply tap this line with your finger. FaceID or TouchID will ask you to confirm your identity. Once verified, the dots will turn into readable text, which can be copied to the clipboard.
For devices running older versions of iOS (15 and below), there is no direct method. The only legal option is to use iCloud Keychain on a Mac. By going to
Bunch of keys(Keychain Access) via Spotlight search on macOS, you can find the name of your network, double-click it, check the "Show password" box and enter the password for your Apple account.WPS Method: Does it Work Today?
Technology Wi-Fi Protected Setup It was created to simplify connecting devices without entering long passwords. The idea was to use a button on the router or enter an 8-digit PIN. For a long time, there was a vulnerability that allowed someone to brute-force this PIN and then obtain the main network password.
Today the situation has changed dramatically. Most router manufacturers (TP-Link, Asus, Keenetic) have either completely removed the WPS function from firmware or implemented brute-force protection. If you try to use a WPS testing app on a modern router, you'll likely get an error or be blocked after several attempts.
In addition, for any WPS-related methods to work on an Android smartphone, you must have root rightsA regular app can't send a special request to disable/enable the WiFi module in monitor mode, which is necessary for this operation. Rooting modern phones is difficult, dangerous (you can lose your warranty and access to banking apps), and often impossible due to bootloader locks.
⚠️ Warning: Attempts to activate WPS through third-party programs may cause the phone's network module to freeze or a driver conflict, which will require a complete reset of the device.
Legal aspects and security
Using someone else's WiFi without permission is not only a technical issue but also a legal one. In most countries, accessing a secure network without the owner's knowledge is classified as computer fraud or unauthorized access.
Even if you somehow managed to connect, you don't know who else is on that network. By connecting to untrusted access points (for example, "Free_WiFi_Moscow" in a park), you risk giving up your data, logins, and passwords to attackers. The owner of such a network can intercept all traffic unless encryption is used. HTTPS.
To protect your own network, it is recommended:
- 🔒 Use a complex password containing letters of different upper and lower case, numbers, and special characters.
- 🚫 Disable the function
WPSin the router settings. - 📡 Regularly update your router firmware to patch vulnerabilities.
- 👥 Create a guest network for visitors, isolated from your personal devices.
What does the network administrator see when you connect?
The router owner can see your device's MAC address, connection time, and the amount of data transferred. If the network is corporate or public and requires authentication, the domains visited may be visible (but not the page content if HTTPS is used).
Frequently Asked Questions (FAQ)
Is there an app that is guaranteed to hack any WiFi?
No, such apps don't exist in the public domain. Those that promise 100% success are either viruses or use stolen password databases. Modern encryption methods (WPA3) are mathematically resistant to simple brute-force attacks.
Is it possible to find out the password if the phone is already connected, but I forgot it?
Yes, it's possible. Android 10+ and iOS 16+ have built-in features for viewing saved passwords in WiFi settings. Older versions of Android require root access to access the system file.
wpa_supplicant.conf.Is it safe to use public WiFi networks in cafes?
Without additional security measures, no. It's recommended to use a VPN service to encrypt your traffic and avoid conducting financial transactions (such as banking) on open networks.
Is it true that you can read a password via NFC?
No, NFC (Near Field Communication) technology has a very short range (a few centimeters) and is not designed for transmitting WiFi network parameters over a distance. It is impossible to read a password through a wall using NFC.
