It's quite common to need to connect a new device to a wireless network but have forgotten its password. Owners of flagship smartphones such as Samsung Galaxy S10, often find themselves confused because the Android system hides password characters by default for security reasons. However, in modern versions of the operating system, this problem can be resolved using built-in tools, without the need for jailbreaking or complex utilities.
You don't need to search through old notes or try to guess the combination by trial and error. All you need is a phone that's already connected to the desired network or has connected to it before. Android system stores connection data in a secure vault that can be accessed through the standard settings menu if you have permission to access the device's lock screen.
In this article, we'll detail the steps for retrieving a saved access key. We'll cover the built-in features, cloud backup capabilities, and the nuances of working with QR codes. This will allow you to quickly restore internet access on any device.
Using the QR code feature in Settings
The easiest and fastest way Samsung offers in One UI is to generate a QR code for connection. This feature was introduced to simplify users' lives, allowing them to share network access with a single scan. To get started, open your smartphone's settings and go to Connections.
Here you should select the item Wi-Fi and find the name of the network you need the password for. A button or QR code icon will appear next to the network name (or when you tap the gear icon, depending on your firmware version). Tapping it will generate a pattern. An image will appear on the screen containing encrypted information, including the network's SSID and the password itself.
- 📱 Open
Settingson your Samsung S10. - 📡 Go to the section Connections and select Wi-Fi.
- 🔍 Click the gear icon next to your active network.
- 📸 Click the button QR code at the bottom of the screen.
However, simply seeing the image isn't enough unless you have a second phone to scan it. Fortunately, Samsung's interface often allows you to see the password in text directly beneath the QR code, or it can be scanned with any barcode scanner that displays a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;In this line, the characters after P: and before ;; and there is your desired password.
⚠️ Attention: To display the QR code and password, the system will require you to verify your identity. You will need to enter your screen unlock PIN, fingerprint, or iris scan, as this action is considered a disclosure of confidential information.
It's important to understand that this method only works if your Samsung S10 is already connected to the network or has connected in the past and saved the profile. If you've never connected to the router from this device, this method won't work. It's also worth noting that on some corporate networks with advanced security settings, password display may be blocked by the administrator.
The menu interface may vary slightly depending on your Android version and One UI. If you don't find the QR code button right away, try tapping the network name or the gear icon to the right of it—the functionality is often hidden in a secondary menu.
View saved networks via Google Account
The Google ecosystem offers another reliable way to restore access. Starting with Android 10, Wi-Fi passwords are synced with your Google account if the backup option is enabled. This means that even if you reset your phone, your passwords will be restored automatically when you sign in to your account on a new device.
To view saved keys, you need to go to your Google account settings. On the Samsung S10, this is done via Settings → Accounts and archiving → Account managementSelect your primary Google account and find the section related to security or sync. In newer versions of the interface, it's easier to navigate this path. Google → Autofill → Google Autocomplete.
Inside the autofill menu, select Wi-Fi networksHere you'll see a list of all the networks for which passwords are saved in your profile. Clicking on a specific network will prompt you to confirm your identity (FaceID, fingerprint, or pattern). After successful authentication, you'll see the network name and the password field, which you can expand by clicking the eye icon.
- 🔐 Log in
SettingsSamsung smartphone. - 👤 Select a section Google or Accounts.
- 📂 Go to the menu Autofill → Google Autocomplete.
- 📡 Select an item Wi-Fi networks to view the list.
This method is particularly convenient because it allows you to view passwords not only from your phone but also through a computer browser by logging into your Google account at passwords.google.com. This makes managing wireless network access cross-platform and device-independent.
⚠️ Attention: If you recently changed your Google account password, syncing may take some time. Make sure your Samsung S10 has a stable internet connection to update your security information.
Why might the password not sync?
Wi-Fi password syncing may not work if Google Backup is disabled on your device, you're using an enterprise profile with security policies that prohibit cloud key storage, or if your device was reset to factory settings without first uploading data to the cloud.
Using the Google Wi-Fi app and Google Home
Samsung S10 owners often use additional utilities from Google to manage their smart home and network. The application Google Home (formerly known as Google Wi-Fi) can also store and display passwords for networks you manage or are connected to. This is especially useful if your router supports Google's management protocols.
Launch the application Google Home on your smartphone. In the main menu, select the "Wi-Fi" device or your access point. In the network management menu that opens, find the section Password or ShareThe app may prompt you to show a QR code or a text version of the password. The functionality here is similar to the system version, but sometimes the Google Home interface provides more convenient access to the connection history.
It's worth noting that for this method to work, your phone must have an active internet connection so the app can verify the data with the Google server. If the network you're looking for the password for isn't currently providing internet access (for example, the router is frozen), this method may not work, and it's better to use Android's local settings.
The advantage of using ecosystem apps is their deep integration. You don't need to search for hidden menus or enter commands. All data is structured and accessible in a clear format. Furthermore, Google Home not only lets you view your password but also create a guest network with temporary access, enhancing the security of your primary connection.
Checking the password via the router (web interface)
If none of the phone methods work, or you want to change the password to a more complex one, you can access the router's settings. The Samsung S10 makes it easy to access the router's control panel if your smartphone is connected to its network (even without internet access, via a local network).
Open any browser on your phone (Chrome, Samsung Internet) and enter the router's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1The exact address is often written on a sticker on the bottom of the router. After entering the address, the system will ask for a username and password to access the admin panel. By default, this is often admin/admin or admin/password, if you haven't changed them.
Once you're in the interface, you'll need to find the section related to wireless networking. It might be called Wireless, Wi-Fi, Wireless mode or WLAN. Within this section, look for the subsection Security (Security) or Wi-Fi settingsThere will be a field there. Wireless Password, Pre-Shared Key or PasswordThere's often a "Show Password" checkbox next to it; unchecking it will reveal the symbols.
| Router brand | Typical IP address | Password path (approximate) | Default login |
|---|---|---|---|
| TP-Link | 192.168.0.1 | Wireless -> Wireless Security | admin |
| ASUS | 192.168.1.1 | Administration -> System or Wireless | admin |
| D-Link | 192.168.0.1 | Wi-Fi -> Security Settings | admin |
| Keenetic | 192.168.1.1 | My Networks and Wi-Fi -> Home Network | admin |
| Tenda | 192.168.0.1 | Wireless Settings -> Wireless Security | admin |
This method is universal, as it doesn't depend on your Android version or phone model. The main thing is to know the login address and administrator credentials. If you changed your router password and forgot it, you may need to reset the router to factory settings (press the Reset button), which will require you to set up your internet connection again.

Third-party applications and their limitations
The Google Play Store offers numerous apps that promise to reveal saved Wi-Fi passwords. However, Samsung S10 owners should exercise extreme caution. Starting with Android 10 (and the S10 has a newer version), Google has blocked apps from directly accessing system files. wpa_supplicant.conf, where the keys are stored, without superuser rights (Root).
This means that most apps that don't require root access are essentially just QR code scanners or wrappers for the system settings we've already discussed above. They can't extract passwords from deep within the system unless the operating system itself allows it. Root-required apps can do this, but gaining superuser access on a Samsung S10 can void the warranty and disrupt banking apps (Samsung Pay, Google Pay).
- 🚫 Do not install dubious "Wi-Fi Hacker" applications.
- 🔒 Android 10+ system restrictions block access to password files.
- ⚠️ Root rights may disrupt the operation of protected applications (banking, payment).
- ✅ Use only proven password managers or built-in tools.
If you still decide to get Root rights, you will need programs like WiFi Password Viewer Or file managers with root access (such as Root Explorer). But remember, this is for advanced users. For routinely viewing your home network password, it's much safer and easier to use the QR code method or log into your router.
⚠️ Attention: Installing apps from unknown sources or gaining root access reduces the overall security of your device. Attackers can exploit these vulnerabilities to steal other data, including social media logins and passwords.
What to do if nothing helps
There are times when your phone won't connect to the network, the QR code isn't displayed due to a system error, and access to the router is lost. In these situations, the last, but most effective, option is to physically access the router. If you have access to the router, locate the "Password" button on its body. WPS.
WPS (Wi-Fi Protected Setup) technology allows you to connect your device without entering a password. On the Samsung S10, this feature may be hidden in the Wi-Fi menu. Tap the three dots in the corner of the Wi-Fi settings screen, select Additionally and find the item WPS buttonPress it, and then within 2 minutes, press the physical WPS button on the router. The phone will connect automatically.
After a successful WPS connection, the password will be saved to your phone's memory again. You can now use the first method in this article—generate a QR code in the Wi-Fi settings and view the saved password, as your device now considers itself authorized to the network.
As a last resort, if you need a password to connect to your computer and only have your phone handy without the ability to display a QR code (for example, if you don't have a second screen), you can use a USB modem. Connect your Samsung S10 to the computer with a cable and enable it in your phone's settings. Modem mode → USB modemThe computer will receive internet access via the phone, and you can access the router settings through a browser on your PC to view or change the password.
Frequently Asked Questions (FAQ)
Is it possible to view the Wi-Fi password on a Samsung S10 without unlocking the screen?
No, this is not possible. For security reasons, Android requires owner verification (PIN, fingerprint, or face) to display saved passwords and generate QR codes. This protects your data if your phone falls into the wrong hands.
Where is the password physically stored on the Samsung Galaxy S10?
Passwords are stored in a system file /data/misc/wifi/wpa_supplicant.confAccess to this file is restricted to regular apps without root access. Users can only see it through secure system settings or a Google account.
Why did my saved passwords disappear after updating Android?
Passwords are usually saved. If they're missing, you may have reset your network settings, deleted your Google account without syncing, or upgraded from a very old version of Android with different storage mechanisms. Check passwords.google.com.
Is it safe to scan someone else's Wi-Fi QR code?
Scanning the code is safe; you're simply connecting to the network. However, be careful with public Wi-Fi networks—data transmitted there can be intercepted. Use a VPN when connecting to unknown networks.
Is it possible to recover the password if the phone has never connected to this network?
No, a phone can't know the password for a network it's never connected to and whose data hasn't been downloaded from Google's cloud backup. In this case, only the router or a question from the network owner can help.
