Revoking data access authorization to a specific computer on Samsung devices

I connected a Samsung smartphone to a Windows computer through a USB cable and had the usual pop-up: > **Allow access to phone data?** > > The connected device will be able to access data on this phone. > > DENY ALLOW I checked "ALLOW," but I'd like to revoke this authorization, and I cannot. When I plug and unplug the computer, the phone is immediately visible and I can access its data from the computer. I tried to uninstall the mobile from the *device manager* (and rebooted the computer, just to be sure...). I shut down the mobile and restarted it. But as soon as I plug it again, it is accessible from the computer and reappears in the *device manager*. Strangely enough, while the phone is entirely removed from the *device manager*, it is still listed in the *autoexecution* section of the *control panel*. When connected, I could also access *USB parameters* on the phone, that are not accessible otherwise. I can shut the access by choosing "charge only," but it's not permanent (when unplugging and plugging again, it goes back to file transfer mode). Looking on the internet and on this forum, I only found the opposite question (people who checked "DENY" and would like to "ALLOW" now; but that's not an issue for me as, in this case, unplugging and plugging again makes the popup appear again). The closest related solution I found was to revoke USB debugging authorization in developer mode, but it seems strange and unrelated to a mere access to the mobile folder. I didn't dare test this option.
