When I am at where there is no wifi facility, I switch on mobile data on my phone and enable wifi hotspot. I browse the internet on my laptop using this WiFi. I am able to connect to this wifi on my laptop but it does not ask me any password. So, I risk my wifi connection being used by other people too. How can I set a password on Wifi hotspot so that only I can access it or those with whom I have shared the password?
My phone has an android jelly bean operating system.
