Forgot your Wi-Fi access key on your Samsung and can’t connect a new device? Owners of smartphones with the One UI shell can instantly find out the saved password directly in the Android settings without installing third-party utilities, however, the procedure will vary depending on the firmware version and the specific model of the gadget.
Previously, retrieving the secret code required obtaining root access, which entailed loss of warranty and the risk of turning the device into a “brick.” Today, engineers of the South Korean corporation have implemented the generation function QR code directly into the system settings. This method is the safest and most accessible for the average user, which does not require deep technical knowledge or installation of third-party software.
In this article we will analyze in detail all the current methods that allow you to find out the Wi-Fi password on an Android Samsung phone. We will look at the standard system tools, the ability to scan QR tags, as well as specific methods for older versions of the software. It is important to understand that data security remains a priority, so access to this information sometimes requires additional authentication through a fingerprint or screen unlock PIN.
Viewing the password through Wi-Fi settings on new versions of Android
Starting with version Android 10 and in more recent updates One UI 3.0 and higher, the company Samsung implemented a native ability to view saved networks. To do this, the user does not need to install additional applications or obtain superuser rights. Just go to the standard settings menu, where the system stores the configuration of wireless connections.
The process begins by going to the section Settings, where you need to select the item Connections. Next, click on the icon Wi-Fi. The list that opens will display all available networks, as well as those to which the phone has previously connected and saved data for automatic connection. If you are within range of the desired network, it will be marked as “Connected.”
Click on the gear icon next to the name of the desired network. A QR codebutton will appear at the bottom of the network information window that opens. After clicking on it, the system may request identification confirmation using biometrics or a pattern. This is a security measure that prevents unauthorized persons from accessing confidential information in case of theft of the phone.
⚠️ Attention: The QR code viewing function may not be available on devices released before 2019, or on models with reduced firmware versions for certain regions. In this case, the interface may differ from that described.
After successful authentication, a square code and, in most cases, a text line with a password below it will be displayed on the screen. If the text is hidden by dots or asterisks, you will need to take a screenshot or use a second smartphone to read the code. This is the most reliable method for modern devices of the series Galaxy S, A i Note.
☑️ Checking access to settings
Using a QR code to transfer data
Even if on the screen of your smartphone Samsung the password is displayed in encrypted form (for example, hidden by symbols), the generated QR code contains all the necessary information in clear text. This is a universal standard that allows you to quickly transfer network data to another device without the need to manually enter long and complex combinations of characters.
To retrieve the password, you will need a second smartphone with a camera and a QR code scanner installed. In modern phones Samsung the scanner is built directly into the application Camera. Just point the lens at the code displayed on the first device. The system will automatically recognize the tag and offer to connect to the network or show a pop-up notification with details.
The notification that appears after scanning often indicates the name of the network (SSID) and the access key itself in text format. If the camera does not show the text right away, you can use third-party applications for reading QR codes from the store Google Play. Utilities such as QR Scanner or Bixby Visionare guaranteed to decrypt the contents of the image.
This method is especially convenient when you need to connect a guest or a new device, such as a tablet or smart light bulb. You don't have to dictate your password and risk getting the characters wrong. Just share your screen and the connection will happen automatically. This saves time and reduces the likelihood of errors when entering manually.
If the password text is not displayed under the QR code, take a screenshot of the screen with the code, open it in the Google Lens application, and the system itself will recognize and show the text line with the password.
Restoring access on older versions of Android without Root
Owners of devices running on the basis Android 9 Pie and below face security restrictions. In these software versions, the function of generating a QR code with a password display is often missing or implemented differently. Direct viewing of saved keys in settings is not possible without special access rights to system files.
However, there is a workaround that does not require hacking the system. If you have a computer and USB debugging is enabled, you can try to extract the data through console commands, although this requires some skill. An easier option is to use the function Google Smart Lock or synchronization with a Google account, if it has been previously configured.
It is also worth checking the backup copies of your settings. Some password managers built into your browser Chrome or account Samsung Cloudcan save data about Wi-Fi networks. Go to your Google account settings via the web interface on your PC and check the “Security” or “Password Manager” section. Saved logins and keys from networks you have ever connected to can be stored there.
If none of the software methods worked, the only legal way remains is to reset the router settings. This is a last resort as it will require reconfiguring all network equipment. However, this guarantees access if you physically have access to the router and can press the reset button.
Why can't you see the password on older Androids?
The system file wpa_supplicant.conf, where passwords are stored, in older versions of Android is protected by access rights that allow reading only by processes with superuser (root) privileges. Without these rights, ordinary applications and settings cannot read this file.
Obtaining root access and viewing system files
For advanced users who need to find out the password on a device with old firmware and who are willing to take risks, there is a method with obtaining root access. This process gives full control over the phone's file system, allowing you to read any configuration files, including those where Wi-Fi encryption keys are stored.
After successfully rooting the device (using utilities like Magisk or KingRoot), you need to install a file manager that supports superuser rights, for example, Root Explorer or Solid Explorer. By giving the application root access, you can go to the directory /data/misc/wifi/.
This folder contains a file named wpa_supplicant.conf. By opening it with any text editor, you will see a list of all networks to which the phone was connected. Opposite each network (SSID) a parameter will be indicated psk, the value of which is the required password in clear text.
| Parameter | Value | Description |
|---|---|---|
network={ |
- | Start of the network configuration block |
ssid |
"Home_WiFi" | Wireless network name |
psk |
"MySecretPass123" | Network password (access key) |
} |
- | End of configuration block |
⚠️ Attention: Obtaining root access will void the warranty on the Samsung device and may lead to inoperability of banking applications (Samsung Pay, Google Pay) due to Knox protection being triggered. Proceed at your own risk.
This method is the most powerful tool in the arsenal of a mobile device repair and configuration specialist, but it requires great caution. Any incorrect action when editing system files can lead to a cyclic reboot of the phone or complete loss of data.
Root access opens the wpa_supplicant.conf file, where passwords are stored in clear text, but this violates the integrity of the Knox security system.
Third-party applications for password recovery
B store Google Play there are many applications that promise to show saved Wi-Fi passwords without root access. However, it is important to understand how they work. Most of these utilities, for example WiFi Password Viewer or WiFi Key Recovery, actually require superuser rights to perform their main function.
Applications that work without Root usually act differently: they do not “hack” the password, but use system APIs to create an access point or generate the same QR code that is available in the settings. In fact, they are just a convenient shell over the standard Android functions, sometimes with a nicer interface or additional network management capabilities.
Some apps use the brute force method or checking against databases of common passwords if the router has not changed the factory settings. This may work for older routers where users did not change the default key found on the device label. However, for modern secure networks this method is useless.
When installing such software, carefully read the permissions that the application requests. Avoid apps that require access to contacts, microphone or SMS if their functionality is stated only as viewing Wi-Fi. This may be a sign of malware that collects the user's personal data.
What to do if the password is lost and the phone is not connected
The most difficult scenario occurs when the phone has never connected to the desired network (or the data has been deleted) and the password is forgotten. In this case, the methods described above will not work, since there is simply no saved configuration in the device memory. Here you need to act through physical access to the router.
Inspect the router case. There is almost always a sticker with technical information on the bottom or back panel. The factory network name (SSID) and standard password (Wireless Key / PIN) are indicated there. If you have never changed these settings, then the combination of symbols from the sticker will be suitable for connection.
If the standard password has been changed and the new one has been forgotten, you will have to reset the router to factory settings. To do this, find a small hole with the inscription Reset. With the power turned on, press it with a paper clip and hold for 10-15 seconds until the indicators blink. After this, the device will return to its “out of the box” state, and the password will be the same as on the sticker.
Remember that after resetting the router, you will need to reconfigure the Internet connection settings (login and password from the provider) if they are not automatically updated. Make sure you have your ISP agreement on hand before performing this procedure.
⚠️ Note: Interfaces and menu layout may vary slightly depending on your Samsung model and One UI version. If you do not find the described item, check the system updates or refer to the official documentation for your specific model.
Frequently asked questions (FAQ)
Is it possible to find out the password for someone else's Wi-Fi through your phone?
No, this is not possible using legal methods. The methods described in the article only work with networks to which your phone already connected has saved data in memory. Selecting a password for someone else's network is a violation of the law and ethical standards.
Why did the QR code button disappear after an Android update?
In rare cases, after major firmware updates, settings may get lost or the interface may change. Try clearing the Settings app cache or checking if the item is hidden in the additional menu (three dots in the corner of the screen). Also make sure that you are in the menu of the exact network you are connected to.
Is it safe to save passwords in the Samsung or Google cloud?
Yes, it is safe. Data is encrypted during transmission and storage. Synchronization makes it easy to restore access to networks on new devices when logging into the same account, eliminating the need to remember complex combinations of characters.
Can I see the password if the phone is broken and the screen does not work?
If the screen does not respond to touches, but the phone turns on, you can try connecting a USB mouse via an OTG cable for navigation. However, if you need to enter a pattern key or a fingerprint to confirm viewing a QR code, it will be extremely difficult to do this without a working screen or scanner.
Does this method work on Samsung Galaxy Tab tablets?
Yes, the operating system Android and shell One UI tablets function similarly to smartphones. The process of viewing a password through Wi-Fi settings and generating a QR code is completely identical and works on all modern models of Samsung tablets.
