Using programs like WiFi Password Viewer Requires full access to the file system. Without root access, these apps will only show stars or require a paid subscription for features that often don't work on newer versions of Android due to security enhancements.
The rooting process Samsung enables bootloader unlocking, which triggers the flag KnoxThis irreversibly disables the secure features of Samsung Pay and Secure Folder and may void your official warranty.

Why can't I just view the password on my Samsung A12 without a QR code?
Starting with Android 10, Google blocked apps' direct access to WiFi configuration files for security reasons. Without root access, no app from the Play Market can read saved passwords for other networks. The QR code method is the only legal way to bypass this restriction, as the system automatically decodes the password for the user after authentication.
What to do if the QR code is not generated?
If the QR code button is missing or not working, check for system updates in the section Software updateAlso, try restarting your smartphone. In rare cases, the issue may be related to the cache of the system "Settings" app, which can be cleared through the app menu.
Is it possible to find out the password for someone else's WiFi network?
No, there's no legal way to find out the password for a network your phone has never connected to. All apps that promise to "hack" WiFi are either scams or viruses. Access is only possible if the network is open (without a password) or if you have physical access to the router and the WPS button.
