It's quite common to have friends over or need to connect a new gadget to your home network, but you've completely forgotten the Wi-Fi password. Fortunately, modern smartphones running the operating system Android They store this data and make it easy to retrieve without having to delve into router settings or remember complex character combinations. This is a built-in security and convenience feature that has become standard in the latest versions of mobile OS.
However, the process of recovering a forgotten character combination directly depends on the software version installed on your device. Owners of newer models from Samsung, Xiaomi or Google Pixel Users of older devices can do this with just two taps, while those with older devices will have to resort to more complex methods or third-party software. In this article, we'll cover all available options in detail, from built-in system tools to advanced techniques for experienced users.
Standard tools for Android 10 and later
Starting with the tenth version of the operating system, engineers Google We've implemented a convenient network access sharing mechanism that automatically generates a QR code. This code contains all the necessary information for connection, including the network name (SSID) and a security key. To use this feature, you don't need special apps or superuser rights; you only need access to the settings menu of your current connection.
The process is as follows: first, you need to unlock the screen and open the quick settings panel or the main settings menu of the device. Find the icon Wi-Fi and tap it to see a list of available networks. If you're already connected to the desired router, simply tap the active network name or the gear icon next to it. A connection information window will open on the screen, with the same QR code at the bottom or center.
- 📱 Point the other phone's camera at the code to automatically connect without entering a password.
- 👁️ Click the eye icon or use the "Show password" feature if it's available in your shell.
- 📸 Take a screenshot of the screen with the code so you can easily scan it with any QR scanner.
- 🔒 Please note that to access these settings, the system may require unlocking via PIN or fingerprint.
It's important to understand that visual display of the text password itself (a set of letters and numbers) is not available on all smartphones, even with the latest Android operating system. Some manufacturers, such as Huawei or Honor in their shells EMUI And Magic UI, may hide the text version, leaving only the QR code for security. In this case, to find the actual text string, you'll need to use additional methods, which will be discussed below.
Using a QR code to get a text password
If your phone only displays a graphic code but doesn't display a text password, that's not a problem. Modern technology makes it easy to decode this information. You'll need any smartphone with a camera and a QR code scanning app installed, or a built-in scanner in the camera, which is found in most modern models. Xiaomi, Samsung and other brands.
After scanning the code you generated on the first phone, the app will return a data string. It will look something like this: WIFI:S:MyNetwork;T:WPA;P:SuperSecret123;;. Here WPA indicates the encryption type, MyNetwork — the network name, and after the symbol P: The password you're looking for is hidden. In this case, it will be SuperSecret123.
It's worth noting that the QR code format is standardized, so it can be read by almost all applications. However, be careful when copying it: sometimes extra characters may be added to the end of the string, which the system will interpret as part of the password, leading to a connection error. Always ensure that the scanned string ends correctly, without any extra spaces or punctuation after the password.
⚠️ Attention: Don't use online services to decrypt QR codes containing passwords for your personal networks. By uploading the image to a third-party server, you are potentially transmitting information about your network to third parties. Use only offline scanners or built-in system tools.
Checking saved networks on older versions of Android
Owners of devices running on Android 9 (Pie) and earlier versions face security restrictions imposed by Google. In these OS versions, direct access to Wi-Fi configuration files is blocked for regular apps. However, if your smartphone has Root rights (superuser rights), you can still access the system files where all the passwords ever entered are stored.
To view the data you will need a file manager with root access, such as Root Explorer or ES File Explorer (in older versions). After obtaining access rights, you need to navigate to the system path: /data/misc/wifi/In this folder there is a file called wpa_supplicant.confIt is here that the names of networks and access keys to them are stored in open form.
| Parameter | Description | Where to find |
|---|---|---|
| ssid | Wireless network name | Inside the network block |
| psk | Passphrase (security key) | The string psk="your_password" |
| proto | Security protocol | Usually RSN or WPA |
| key_mgmt | Key management method | Often WPA-PSK |
Opening the file wpa_supplicant.conf Using any text editor, you'll see a list of all networks the device has connected to. Look for the block corresponding to your router and the line pskThe value in quotation marks after the equal sign is your password. If instead of text there is a set of characters like #WPA_KEY, this means that the password is encrypted or hashed, and it cannot be read directly without additional utilities.
What are Root rights?
Root access is the equivalent of administrator rights in Windows. Gaining full access to the Android file system allows you to modify system files, remove built-in apps, and access hidden settings, but it also voids the device's warranty and can cause instability.
Third-party apps for access recovery
If the built-in methods don't work and you don't want to get root rights, you can try using specialized software from the store. Google PlayThere are many apps that market themselves as "Wi-Fi managers" or "password recovery" apps. They attempt to circumvent system restrictions by exploiting special APIs or accessibility features.
One of the popular solutions is the application WiFi Password Viewer or similar. The principle of their operation is based on an attempt to read stored data through channels permitted by the system. On some phone models (especially Xiaomi with MIUI shell or Samsung) these applications can successfully display the password due to the specifics of the interface implementation by the manufacturer.
- 📥 Download a proven app with a high rating and many reviews.
- 🔐 Grant the app the necessary permissions (often access to location and storage is required).
- 📋 Click the scan or view saved networks button.
- 👀 If the app is not rooted, it may only show a QR code or not find data at all on newer versions of Android.
Be careful when installing such software. Many "free" programs are cluttered with ads or may contain malicious modules. Always check the permissions the app requests: if a simple password viewer asks for access to your contacts or SMS messages, it's a clear sign of a scam. It's better to choose products from reputable open-source developers.
⚠️ Attention: App interfaces and features may change after operating system updates. What worked on Android 8 may no longer work on Android 13. Always check the app requirements against your software version in the store description.
Using a Google account for syncing
Ecosystem Google Offers smart home functionality and password syncing via your account. If Chrome or system password syncing is enabled on your device, saved Wi-Fi keys can be accessed through your Google account's web interface. This is especially useful if your phone is broken or lost, but you need to know the password to connect to another device.
To do this, you need to go to the page passwords.google.com From any computer or another smartphone, log in with the same account as the one on the phone that lost access. You can sometimes find your Wi-Fi network name in the list of saved data. However, this feature doesn't work with all providers or on all devices, as it depends on the smartphone manufacturer's security policies.
If the password is there, you can view it by completing an additional security check (entering your Google account password). This is one of the most secure methods, as it doesn't require physical access to the phone itself, which was previously connected to the network. The main thing is to remember the password for your Google account.
Resetting your router as a last resort
When none of the software methods work and the password is urgently needed, physical access to the router itself remains. On the case of most routers (for example, TP-Link, Asus, Keenetic) There's a sticker with the factory network name and password. If you never changed this information during initial setup, the problem is solved—just look at the bottom of the device.
If the password has been changed and lost, you can reset the router to factory settings. To do this, find the small indentation marked Reset On the back panel. With the power on, press it with a paperclip or toothpick and hold for 10-15 seconds until the lights blink. After rebooting, the router will use the password printed on the sticker.
☑️ Steps to reset your router
This method has a serious drawback: after resetting, you'll have to reconfigure your internet connection settings (username and password from your ISP) if they weren't automatically updated. Therefore, only use this method if you're confident you can restore your ISP settings, or if they don't require additional authorization (e.g., Dynamic IP connection type).
Questions and Answers (FAQ)
Is it possible to find out someone else's Wi-Fi password if I'm connected to it?
Technically, if you're connected to a network on Android 10+, you can generate a QR code to connect another device. However, this doesn't grant you permission to use the network without the owner's permission. From the system's perspective, you're an authorized user, so the phone will allow you to share access, but it's only ethical to do so with the network owner's consent.
Why is there no "Show Password" button on my Android 11?
Smartphone manufacturers implement the interface differently. In stock Android (Pixel, Motorola), they often only show a QR code. In custom skins OneUI (Samsung) or MIUI (Xiaomi) may have an "eye" button. The absence of a button doesn't mean the password can't be found out—use another phone's camera to scan the QR code.
Is it safe to save Wi-Fi passwords to my Google Account?
Yes, Google uses encryption when transmitting and storing data. However, if your Google account is hacked, the attacker could gain access to your password history. We recommend using two-factor authentication to protect your account.
What to do if the wpa_supplicant.conf file is empty?
If the file is empty or missing, it means there are no networks saved on the device, or the app doesn't have read permissions for this system folder. Make sure you've granted the file manager full root permissions. Also, the file path may differ on some newer devices.
