It's a common occurrence when friends or new clients come over and ask to connect to a wireless network. You eagerly reach for your smartphone to scan a QR code or simply dictate a complex set of characters, only to realize you don't remember it yourself. On modern devices Samsung Galaxy This problem can be solved using the operating system's built-in tools, but many users still don't know about this option. Instead of digging into the router settings or searching for your ISP contract, a few simple taps on the screen are all it takes.
operating system Android, starting with version 10 and especially in the shell One UI Samsung has significantly simplified network connection management. Saved access keys are no longer locked away, but are now available for viewing as a QR code or text field. This is designed for user convenience, but requires specific actions to activate display. In this article, we'll cover in detail all the current methods for recovering lost internet access data.
Please note that the menu interface may differ slightly depending on your device model and software version. The owner of the flagship Samsung S24 and a budget user Galaxy A14 The options may have slightly different names, but the logic remains the same. The main thing is to have access to the lock screen and know the PIN or biometric data to verify your identity.
View your password via QR code in Settings
The fastest and most reliable way to view your saved access key is to use the QR code generator feature. This option is built directly into the shell's network connections control panel. One UIYou don't need to install any third-party apps or gain root access. Simply follow the steps below to get a visual representation of the key.
First, unlock your smartphone's screen and go to the main app menu. Find the "Settings" icon (the gear icon) and tap it. In the list that appears, select "Connections." This is where you'll find all the settings for Bluetooth, NFC, and, of course, Wi-Fi. Next, tap the Wi-Fi icon to see a list of available networks.
Find the network you're already connected to or saved on your device in the list. Tap the gear icon to the right of the network name. A menu with detailed connection information will open. At the bottom of the screen, you'll see a "QR code" button. Tapping it will generate an image that can be scanned with another device.
- 🔑 Click the "Show Password" button below the QR code to see the text string.
- 📸 Take a screenshot if you need to transfer data to another person remotely.
- 🔍 Use another phone's camera to scan the code without entering it manually.
It's important to note that to display the password text line, the system will require identity verification. This may involve entering a PIN code, pattern, or fingerprint scanning. biometric protectionThis is a standard security measure to prevent data theft by attackers who gain physical access to an unlocked phone.

Using Smart View and Nearby Share
An alternative, but less obvious way to communicate network data is to use an ecosystem Samsung. Function Smart View or Nearby Share Allows you to share connection settings with other devices of the same brand. While this doesn't always display the password in plain text on the sender's screen, it allows you to instantly connect a guest device without having to dictate complex characters.
If your contact also has an Android device, you can use the "Share" feature in the QR code menu. In some firmware versions, when you try to share a QR code image via messaging apps, the system automatically recognizes the data it contains. This can be useful if you need to send a passcode to a friend who is far away.
However, be careful when sharing such data. The QR code contains all the necessary connection information in plain text. Anyone with access to the image will be able to connect to your network. Therefore, it is not recommended to post screenshots of codes on public social media or in chats where other people are present.
⚠️ Important: The QR code is valid indefinitely until you change the password on your router. Do not share the image of the code with strangers, as this is the same as sharing your password in plain text.
Technical details of the QR code
The QR code contains an encrypted string in the format WIFI:S:SSID;T:WPA;P:PASSWORD;;. Special reader apps can decode this string and display the password in clear text, even if Samsung's system itself hides its text display in a specific interface.
Viewing via Google Account and sync
Modern versions of Android actively use cloud synchronization via an account Google. If on your device Samsung If Wi-Fi password syncing is enabled, saved keys can be accessed from any other device linked to the same account. This is especially convenient if the phone you need to retrieve the password from is dead or unavailable.
To test this method, take any computer or other smartphone. Log into the browser using the same Google account as yours. GalaxyGo to your Google account settings at passwords.google.com. You can find your saved data under "Passwords" or "Password Manager."
In the list of saved entries, find the one with the name of your Wi-Fi network. They are often labeled as "android-wifi:SSID_network_name." After tapping the entry and confirming your account password, you will see the password field. Tapping the eye icon will reveal hidden characters. This method works regardless of the phone model, whether it's an older model or an older one. Samsung A50 or the newest S23 Ultra.
| Method | Required access | Complexity | Security |
|---|---|---|---|
| QR code in settings | Unlocking the screen | Low | High |
| Google Account | Access to mail | Average | Average |
| ADB Commands | PC and debugging | High | High |
| Root rights | Superuser | Very high | Low |
Using ADB for Advanced Users
For users who are not afraid of the command line and have access to a computer, there is a method to obtain the password through the Android debug bridge (ADB). This method does not require superuser rights (Root), but it does require enabling developer mode on the smartphone. SamsungThis is a powerful diagnostic tool that provides access to system configuration files.
First, you need to enable developer mode. To do this, go to Settings → About phone → Software informationFind "Build Number" and quickly tap it seven times. The system will notify you that Developer Mode is enabled. A new section, "Developer Options," will then appear in the main Settings menu.
Enable the "USB debugging" option in this section. Connect your phone to the computer using a cable. Install the package on the computer. Platform Tools (ADB). Open a command prompt and enter the command to list saved networks and their keys. The command looks like this:
adb shell cmd wifi list-networksHowever, on modern versions of Android (starting from 10 and above), access to the file wpa_supplicant.conf, where passwords are stored in cleartext, is closed even to ADB without root access. Therefore, this method can only show a list of networks (SSIDs), but not the passwords themselves, unless the device has been previously configured specifically. However, for older models Samsung With Android 9 and below, this method remains working and effective.
Login to the router's web interface
If none of the software methods on the phone itself work, there's always the "hardware" option: accessing the router's settings. To do this, you'll need a device that's already connected to the Wi-Fi network (even if you don't know the password, it has internet access). You'll need to find the gateway IP address, which is usually the address of the router's management page.
On the phone Samsung Go to your Wi-Fi settings, click the gear icon for your active network, and scroll down to "View advanced" or just look in the "Gateway" field. This is usually the address 192.168.0.1 or 192.168.1.1Enter this address into the address bar of your browser (Chrome, Samsung Internet).
The router's login page will open. The default login and password are often listed on a sticker on the bottom of the router itself (e.g., admin/admin). Once you've logged into the control panel, find the "Wireless" section. In the field there, Wireless Password or "Security Key" will display your current password. You can not only view it but also change it to something easier to remember.
⚠️ Please note: The interfaces of routers from different manufacturers (TP-Link, Asus, D-Link, Keenetic) vary significantly. If you are unsure of what you are doing, it is best not to change any settings other than the Wi-Fi password to avoid disrupting your ISP's service.
Issues and limitations in new versions of One UI
Company Samsung regularly updates its shell, introducing new security levels. In the latest versions One UI 6.0 and above, changes in the arrangement of controls may be observed. For example, the "Show Password" button may be hidden in a second menu level or require biometric authentication each time it's clicked.
It's also worth remembering about corporate profiles. If your phone Samsung If the device is used for work and has a corporate security profile (MDM) installed, the network administrator may have prohibited viewing and exporting Wi-Fi passwords. In this case, the system will display a security policy restriction message, and there will be no way to bypass it using standard tools.
Additionally, some models supplied for certain regions or carriers may have limited functionality. If you don't see the above, check for system updates in the section Settings → Software UpdateOften, necessary features are added or fixed with security patches.
Is it possible to find out the password without unlocking the screen?
No, this is not possible. Android's security system requires owner authentication (PIN, pattern, biometrics) before displaying sensitive data, such as network passwords. This protects your data if your phone is lost.
Why is the QR code button grey and unclickable?
This can happen if the Wi-Fi module is turned off, if the network is corporate with special security certificates, or if the phone has parental control/device administrator restrictions.
Will this method work on older Samsung Galaxy devices?
The ability to view passwords via QR code was introduced in Android 10. This functionality is not available on older versions (Android 9 and below). Owners of older devices will have to log in to their router or use third-party apps with root access.
Is it safe to scan other people's Wi-Fi QR codes?
Scanning codes from trusted sources is safe. However, avoid scanning codes from unknown sources, as the QR code may contain not only a Wi-Fi link but also a malicious URL that will open in your browser immediately after scanning.
