It's a common situation when you need to connect a new device to the network, but you've forgotten the password or written it down somewhere in a notebook that's now impossible to find. Fortunately, modern smartphones powered by Android or iOS, often store this data in memory if you've successfully connected to the same access point before. This eliminates the need to reset the router or search for a sticker on the bottom of the device, allowing you to quickly access the information you need directly from your mobile phone screen.
There are several proven methods for retrieving a saved security key, but their availability directly depends on the operating system version and the user's access rights. On newer versions Android 10 and above, as well as in iOS 16, the process is extremely simplified and doesn't require any complicated manipulations. Owners of older devices will have to resort to using special utilities or ADB commands, which requires a little more technical training.
It's important to understand that all the methods described below only work if your phone has previously connected to this network and saved the connection profile. If you've never logged into the network from this device or the data has been deleted, you won't be able to recover the key using standard tools. Below, we'll detail the steps for different platforms, focusing on security nuances and potential manufacturer restrictions.
How to view your password on Android 10 and later
Starting with the tenth version of the operating system AndroidGoogle has implemented a native QR code feature for quickly connecting devices. This feature also allows you to view your saved password in text format, making the process extremely simple and accessible to the average user. You don't need third-party apps or root access; access to the settings menu is sufficient.
To begin, open the default application Settings on your smartphone and go to the section Wi-Fi or ConnectionsIn the list of available networks, find the one you're currently connected to (it will be marked "Connected") and click the gear icon or the network name to the right of it. On some models, for example, Xiaomi or Samsung, the interface may differ slightly, but the logic remains the same.
In the menu that opens, you'll see a "Share" button or a QR code icon. Tapping it will prompt you to verify your identity with a PIN, fingerprint, or Face ID. Once successfully authenticated, the QR code will appear on the screen, along with a text string containing your password. If the text is hidden by asterisks, simply tap the code area or the eye icon to reveal the symbols.
- 🔑 Click the gear icon next to your active Wi-Fi network.
- 📱 Select the "Share" or "QR code" option in the network menu.
- 👁️ Complete biometric verification or enter your unlock PIN.
- 📝 Copy the password displayed under the QR code or scan it with another device.
⚠️ Note: On some custom ROMs (such as older versions of MIUI or EMUI), the password text may not be displayed explicitly, only a QR code. In this case, use another phone's camera to scan it: many cameras can read the code and display it in a notification.
Extracting data on older Android versions (without rooting)
Owners of devices running on Android 9 and earlier versions face security restrictions that hide Wi-Fi configuration files. Viewing saved passwords on these systems is impossible using standard settings menu tools. However, there is a method that doesn't require root access, which relies on creating a backup copy of the settings.
The method involves using Google's backup feature or the manufacturer's built-in tools. You need to create a backup of your device settings and then analyze the resulting file. Often, the settings archive contains a file wpa_supplicant.conf or similar, where all ever saved networks and keys to them are stored in open form.
To implement this method, you may need to connect to a computer and use Android Debug Bridge (ADB)This is a command-line tool that allows you to interact with the Android shell. If USB debugging is enabled on your phone, you can upload the configuration file directly. The command for this looks like this:
adb pull /data/misc/wifi/wpa_supplicant.confThe resulting file can be opened with any text editor on your computer. Inside, you'll find blocks with the network name (ssid) and the corresponding password (psk). If the file is encrypted or inaccessible without root access, this method, unfortunately, will not work without first hacking the system.
What if the file is empty or inaccessible?
If you receive an access error or the file is empty when trying to extract a file, this means that additional security or data encryption mechanisms are enabled on the device. In this case, accessing the password via ADB without root access is impossible. Try using the QR code method if it's available in your firmware version, or contact your network administrator.
Using Root Privileges to Access System Files
The most reliable, but also the most risky way to obtain passwords on old Android smartphones is to have Root rightsObtaining superuser rights removes all access restrictions to system partitions, allowing access to any configuration files. However, this action voids the device's warranty and may lead to system instability.
If your phone is already rooted, you will need a file manager with Root support, such as Root Explorer or Solid ExplorerAfter launching the application, grant it superuser privileges when prompted. Then go to the following path: /data/misc/wifi/This is where the main wireless network configuration file is stored.
Find the file named wpa_supplicant.conf (or wpa_supplicant.conf.bak) and open it as text. Inside, you'll see a list of all networks in the following format:
network={ssid="MyWiFi"
psk="SuperSecretPassword123"
}
Here ssid — is the name of the network, and psk — the password you're looking for. Be extremely careful when editing this file: any syntax error may prevent the Wi-Fi module from working properly until the reset.
- 📂 Install a file manager with Root support (for example, Root Explorer).
- 🔓 Grant the app superuser privileges when prompted.
- 📁 Go to the directory
/data/misc/wifi/. - 📄 Open the file
wpa_supplicant.conftext editor.
⚠️ Warning: Modifying system files without proper knowledge can brick your phone's communication module. Before making any changes, be sure to create a full backup copy of the file by copying it to another folder.
How to find the password on an iPhone (iOS 16 and later)
For a long time the ecosystem Apple was extremely closed when it came to accessing saved Wi-Fi passwords, but with the release iOS 16 The situation has changed dramatically. Now iPhone and iPad owners can easily view the password for any network they've ever connected to, right in their device settings. This feature requires Face ID, Touch ID, or a passcode to be enabled on the device.
To access the data, open the application Settings and go to the section Wi-FiOn the right side of the screen, next to the name of the active network (or any other saved network from the list), a blue information icon, shaped like the letter "i" in a circle, will appear. Click it.
In the menu that opens, find the "Password" line. Initially, the characters will be hidden by dots. Tap this line, and the system will prompt you to complete biometric authentication or enter the screen unlock code. After confirmation, the password will be displayed in clear text and can be copied to the clipboard.
This method doesn't work for devices running older versions of iOS (below 16). The only legal way to find out the password in such cases is to view it on an already connected computer (Windows or Mac) through the network properties or use the router if you have physical access to it.
Specifics of working with different routers
Regardless of the device you're using to access the network, it's important to consider the features of the router itself. Different manufacturers, such as TP-Link, Asus, Keenetic or MikroTik, may implement security protocols and key storage differently. Knowing the router model can sometimes help restore access if standard methods on the phone fail.
Many modern routers support WPS (Wi-Fi Protected Setup), which allows you to connect without entering a password by pressing a button on the router or using a PIN code. Although this feature is considered vulnerable and is often disabled by default, it may be enabled on older models. There are scanner apps that attempt to brute-force the WPS PIN code, but their effectiveness is likely to be negligible by 2026 due to security patches.
It's also worth considering the encryption type. If the network uses an outdated protocol WEP, it is much easier to hack it or recover the password than a network with modern encryption WPA3However, using WEP is strongly discouraged, as such networks are easily eavesdropped on by intruders.
| Security protocol | Year of implementation | Level of protection | Recommendation |
|---|---|---|---|
| WEP | 1999 | Critically low | Replace immediately |
| WPA (TKIP) | 2003 | Short | Not recommended |
| WPA2 (AES) | 2004 | High | De facto standard |
| WPA3 | 2018 | Maximum | Recommended |
⚠️ Note: Interfaces and menu names may vary between router manufacturers. If you can't find the security settings, please refer to the official documentation for your model or the manufacturer's website.
Security measures and protection of your network
Understanding how easy (or difficult) it is to obtain a Wi-Fi password should prompt network owners to consider their own security. If the password can be found via a QR code on the screen of an unlocked phone, then physical access to your smartphone gives access to the entire home network. Therefore, setting a secure PIN code or biometrics on the phone itself is critical.
Furthermore, regularly changing your router password and using complex character combinations (capital letters, numbers, special characters) make life much more difficult for potential hackers. Avoid using simple combinations like your date of birth or a sequence. 12345678Modern video cards are capable of trying millions of simple combinations per second.
It's also recommended to disable the WPS feature on your router if you're not using it, and hide the network name (SSID) if you want to minimize the visibility of your access point to outsiders. Remember that network security is a complex process, not just a single, complex password.
- 🛡️ Use WPA2-AES or WPA3 encryption.
- 🔢 Create passwords that are at least 12 characters long.
- 🚫 Disable WPS in your router settings.
- 📱 Protect access to your phone settings with biometrics.

Frequently Asked Questions (FAQ)
Is it possible to find out a Wi-Fi password if the phone has never connected to this network?
No, this is not possible legally. The phone only stores the data previously entered for successful authorization. If the device has no network record, it has no information to display. In this case, access to the router itself or another device already connected is required.
Is it safe to use Wi-Fi hacking apps from the Play Store?
Most of these apps are either fake or contain malicious code. Real security audit tools (like Kali NetHunter) require in-depth knowledge and often system modification. Apps that promise "one click and you have your password" most often simply steal your personal data or display ads.
What should I do if the QR code doesn't show the password in text?
This depends on the Android version and the manufacturer's shell. If the text isn't displayed, take a screenshot of the QR code and open it with Google Lens or any other QR code scanner on another device. Often, the code will contain a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;, where after P: and your password is found.
Will my phone reset my Wi-Fi password when I update my system?
Typically, an over-the-air (OTA) update preserves all settings, including saved Wi-Fi networks and passwords. However, upgrading to a major Android version (for example, from 11 to 12) or performing a factory reset will erase all data.
