thanks for the suggestions, but i was speaking about sharing to my college systems.
i cant connect any usb deives and it will be on different network so dont have that file share option also.
Proton drive files share links are too lengthy to type on manually, my passwords are autotgenrated via keepass so very annoying to type it manually to login to proton account..
To my knowldge signal dont have a web version of it like whatsapp, i cant install the signal client on th college systems.
I was looking for something as easy as whatsapp web, just scan a qr code and files are ready to on the pc.
