- 🔒 Increased security due to data encryption when transmitted via camera.
- 📱 Ease of use on devices with a limited input interface.
- 🔄 Automatic update of profile data on all connected devices.
However, it is worth considering that for this function to work, the application must be installed and authorized on the main device (scanner). Yandex or Yandex Browser. Without first setting up the main account, scanning someone else's code will not work.
⚠️ Attention: Never scan QR codes received from unknown sources or found in suspicious emails. Attackers can use fake codes to gain access to your account.
Preparing the device for scanning the code

Yandex necessary permissions to use it. Without this step, scanning will not be possible.
It is also important to make sure that the latest version of the application is installed on your phone. Outdated versions of the software may not support the latest encryption protocols used to generate access codes. The update can be found in the store Google Play or through the built-in updater.

Authorization via Yandex Browser
An alternative option is to use a mobile browser Yandex Browser. This method is convenient if you do not have a separate search engine application installed, but have a browser with a synchronized account.
Open the browser and go to the main page of the search engine. In the search bar or in the settings menu (three dots in the corner), find the scanner button. It is usually indicated by a characteristic square frame or camera icon. Click on it to activate the scanning mode.
The principle of operation is similar to the application: place the frame over the code. The browser will redirect you to a login confirmation page. Here it is important to check whether the account is used in the browser, since the login will be performed under it.

After successful scanning on the device where login was required, a page with your data will open. This is an ideal option for quickly working with mail or documents on someone else's computer without having to enter a password manually.
What to do if the browser does not see the code?
If Yandex Browser does not respond to the QR code, try increasing the brightness of the target device's screen. Also make sure that the distance between the camera and the code is 15-20 cm. Sometimes a slight shake of the phone helps to better focus the lens.
Using the Yandex widget on the desktop
For users who value maximum efficiency, the company has developed special widgets for the Android desktop. Android. They allow you to launch a QR code scanner with one touch, bypassing opening the main application.

This method is especially useful if you often have to log in to various devices in the office or school. The speed of access to the scanning function in this case is maximum.
- 📲 Quick access without opening the full application interface.
- ⚙️ Ability to customize the widget size depending on preferences.
- 🎨 Various widget design styles to personalize the interface.
It is worth remembering that widgets may consume additional battery power since they are active on the desktop. If saving energy is a priority for you, it is better to use the standard launch through the app.
Solution: errors and ways to eliminate them
Despite the simplicity of the technology, users may encounter technical problems. One of the common errors is the message “Code not recognized” or the loading indicator spinning endlessly. This is most often due to poor lighting or glare on the target device's screen.
Another common problem is the code expiring. Security QR codes are valid for a limited time (usually a few minutes). If you did not have time to scan the code, refresh the page on the target device so that a new one is generated.
There may also be problems with access rights in the system Android. If the application did not ask for permission to use the camera, scanning will not start. Check the privacy settings in the section Settings → Applications → Yandex → Permissions and turn on the camera.
If the camera focuses on the background and not on the code, touch the area of the screen where the QR code is located with your finger to force it to focus focus.
In rare cases, the problem may lie in antivirus software or VPN services that block local requests. Try disabling them temporarily and trying to log in again.
Security measures when logging in via QR
The security of your data is priority number one. The QR code mechanism is designed to meet modern security standards, but the human factor remains the weak link. Never allow others to scan the code on your screen unless you are sure of their intentions.
Always check the device you are logging into. If you see a login request from an unfamiliar device or from another city, immediately deny access and change your password. Notifications about new logins are sent to the application and by email.
It is recommended to regularly check the list of active sessions in your account settings. There you can see which devices have access to your data right now, and, if necessary, end the session remotely.
⚠️ Attention: The interfaces of applications and web versions may be updated. The location of the buttons and the names of menu items may differ slightly from those described in the instructions. Always focus on the current interface in your version of the application.
Regularly checking active sessions and using two-factor authentication is the best protection for your account, even when using QR codes.
