Many users are familiar with the situation of needing to connect a new device to their home network but hopelessly forgetting the access key. Fortunately, modern smartphones have built-in features that allow you to quickly restore this information without having to reset the router or search for your ISP contract. In most cases, the system automatically saves data about connected networks for easy re-authorization.
The process of restoring access varies greatly depending on the operating system of your device. Owners of devices based on Android And iOS There are different ways to solve this problem, determined by the security policies of each platform. Below, we'll detail all the current methods for both systems, including using QR codes and system settings.
It's worth noting that for this procedure to be successful, your phone must already be connected to the target network or have a connection history. If the device has never connected to this router, it will be impossible to obtain the key remotely without physical access to the router itself. Let's look at the step-by-step algorithms for various scenarios.
Password recovery on Android 10 and later
Starting with the tenth version of the operating system AndroidGoogle has implemented a native QR code access sharing feature, significantly simplifying user experience. You don't need root access or install questionable third-party apps. Simply access the standard settings menu, which is accessible on any modern smartphone.
To get started, open the section Settings and go to the item Wi-Fi or Network and InternetFind the network you're already connected to or saved to your device's memory in the list. Tap the network name or the gear icon next to it to open the detailed configuration menu.
In the window that opens, find the button Share or image QR codeThe system may require identification via a fingerprint, facial recognition scanner, or screen unlock PIN. Upon successful authentication, a square code will appear on the screen, with the password itself often (but not always) written in small print underneath.
- 📱 Open Wi-Fi settings on your device.
- 🔒 Click on the desired network to enter properties.
- 👁️ Select the "Share" or "QR code" option.
- ✅ Complete the security verification (Face ID/Touch ID).
⚠️ Note: On some smartphone models (for example, older versions of MIUI or OneUI), the password text may be hidden. In this case, the code is displayed, but the numbers underneath it are missing.
If there's no text underneath the QR code, don't despair. You can take a screenshot and open it through the app. Google Lens (Google Lens) or any other QR code scanner. The system will recognize the image and output a text string with the prefix P: The required access key will be indicated.
How to find the password on an iPhone (iOS 16+)
For product owners Apple was a little less fortunate in terms of longevity of support, as the function of viewing saved Wi-Fi passwords appeared only in the operating system iOS 16If your iPhone or iPad is updated to this version or later, the process takes just a few seconds and doesn't require any additional software.
Go to the menu Settings and select a section Wi-Fi. In the upper right corner of the screen, find the button Edit (or the three-dot icon on iPad). This will open a list of all the networks the device has ever connected to. Tap the blue information icon. (i) next to the desired network name.
In the menu that opens, you will see a field Password, which is hidden by dots by default. Tap this field once. The system will ask you to confirm the action via Face ID, Touch ID or device passcode. Once verified, the dots will turn into readable text that can be copied to the clipboard.
It's important to understand that this feature only works for networks your phone has previously connected to. If you're trying to find out a friend's network password while you're near it but have never entered the key on your iPhone before, this method won't work. In this case, your only option is to ask the router owner for a sticker or use the QR code from their device.
Using a Google Account for Recovery
One of the most effective, but little-known methods is synchronizing passwords through an account. GoogleIf password syncing is enabled on your Android smartphone, Wi-Fi network data is stored in the cloud. This allows you to access your keys even from another device, as long as you know your Google account login information.
To check, follow the path Settings → Google → Autofill → Autofill from Google. Make sure the switch is active. Then go to the section Passwords (or visit passwords.google.com from a computer). The list of saved data may display not only websites but also Wi-Fi network names.
However, it's worth considering security limitations. Google doesn't always display Wi-Fi passwords in plain text in the account web interface; they're often used for automatic logins. However, checking this section can help you find forgotten logins for other services you may have used to log in to captive portal networks (for example, at hotels or cafes).
| Method | Necessary rights | OS version | Complexity |
|---|---|---|---|
| QR code (Android) | No | 10+ | Low |
| Settings (iOS) | Face/Touch ID | 16+ | Low |
| Google Account | Account access | Any | Average |
| Root rights | Superuser | Any | High |
☑️ Check before recovery
Advanced Methods: Root Privileges and System Files
For advanced users whose devices have superuser rights (Root), there is direct access to the system file where all keys are stored. This method is universal and works on all Android versions, including very old ones, but requires some preparation and unlocking the bootloader.
You will need a file manager with root access support, such as Root Explorer or MT Manager. Follow the path /data/misc/wifi/There you will find a file called WifiConfigStore.xml (on newer versions of Android) or wpa_supplicant.conf (on old ones). Open this file with a text editor.
grep -r "psk=" /data/misc/wifi/wpa_supplicant.confFind the tag inside the file <SSID> with the name of your network. There will be a tag next to it. <PreSharedKey> or attribute psk, the value of which is your cleartext password. Be careful when editing system files: any incorrect changes may cause instability in the Wi-Fi module.
⚠️ Warning: Rooting your device will void your warranty and may create security vulnerabilities. Only do this if you fully understand the risks and the need for this access.
What to do if the file is empty?
If the configuration file is empty or doesn't contain the required entries, the data may be stored in the secure KeyStore. In this case, even root privileges won't allow reading the password in plaintext without specialized memory dump utilities, which requires extensive technical expertise.
Alternative methods and applications
There are many applications in Google Play, promising to reveal your Wi-Fi password. Most of them are either useless (as they can't work without root access) or malicious. However, there are legitimate utilities that help manage connections, although they don't always reveal the actual key.
Some smartphone manufacturers (eg. Xiaomi, Huawei) have their own cloud services for backing up settings. If you previously made a full system backup to the manufacturer's cloud service, restoring your phone from the backup may automatically reconnect to the network, even if you don't remember the password.
Physical access to the router is also worth mentioning. If you're at home, turn the router over. There's often a sticker on the bottom that says Wireless Password or WPA KeyIf the password has not been changed since the equipment was purchased, this combination of characters will be valid.
- 🏷️ Check the sticker on the router body.
- ☁️ Use your phone manufacturer's cloud backup.
- 💻 View saved passwords in the Chrome browser (Passwords section).
- 🔌 Reset the router using the Reset button (last resort).
Using third-party password scanners is not recommended. They rely on crowdsourcing (users upload passwords to the database themselves), which compromises privacy. Furthermore, such programs are often overflowing with ads and may contain hidden modules that collect your personal data.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if I've never connected to it?
No, it's technically impossible to find out the password for a network your device has never connected to and whose data hasn't been stored. WPA2/WPA3 encryption protocols are designed specifically to prevent unauthorized key guessing. The only option is physical access to the router or questioning the network owner.
Are password recovery apps safe to use?
Most of these apps either don't work without root access or are scams. They may request access to your contacts, photos, and location. It's recommended to use only built-in operating system tools or trusted file managers if you have root access.
What should I do if the QR code does not show the password text?
This is standard behavior for some Android operating systems. In this case, take a screenshot of the code, open the Google Lens app (or a similar scanner), and select an image from your gallery. The app will recognize the text within the QR code and allow you to copy the password string.
Will resetting network settings on my phone reset the password?
Yes, resetting network settings will delete all saved Wi-Fi passwords, Bluetooth settings, and cellular network settings. Your phone will "forget" all known networks. Therefore, before doing this, make sure you know the password or have saved it in another way.
Is it possible to find out the Wi-Fi password on an Android device using an iPhone?
There's no direct method due to differences in file systems and security policies. However, if QR codes were enabled on Android, you can take a screenshot, send the photo to your iPhone, and scan the code using the standard camera or the Shortcuts app to see the password text.
