restrict two device using same account at the same time - mobile app

I want to mention a situation that I think is wrong.

I did a test today: I accessed a quiz with 2 devices using same account on mobile application. I was able to navigate through the answers on both devices, we could even simulate working in collaboration.

I imagine a situation where two students share the same account and one can see the solution made by the other.

For the browser there is a solution to limit the number of concurrent logins, but for the mobile application what can be done to prevent such situations?

Thanks!
I will try it tomorrow morning.
Regarding the IP, I don't think it is possible to solve the problem. I installed moodle on a virtual server (wsl) and the connection is made through NAT, therefore all connections are seen as coming from the same IP address.

I tested the plugin suggested above today and it seems to work. However, there is a problem: when I try to access from the mobile app a quiz that has the concurrent access restriction set, I get an alert and have to open the quiz in the browser. The thing is that for the browser there is already a functional option in this sense available at: Site administration->Plugins>Authentication->Manage Authentication->Limit concurrent logins.
Therefore, this plugin is also functional for the mobile app or any quiz must be opened in the browser? Maybe it's a problem with me, I'm using android 14.
If it doesn't work for mobile, what is the advantage of this plugin over the above mentioned option available in moodle?

Yes, this plug-in limits the *browser sessions* - mobile devices do not count. Read the discussion on the plug-in page https://moodle.org/plugins/quizaccess_onesession. One option would be to disable Mobile access during the exam. Another one is to make the Safe Exam Browser mandatory for the exam. There may be more.

Using mobile app is more convenient because connection and account are saved. But it's ok to go from app to browser, because don't require to type url or account credentials.
