Right now, we are babysittiig a friend's daughter. She is here with a tablet. I'd like to be able to grant her access to the internet though my wifi but I do not want to type the domestic wifi key into her device.
Could I setup something similar to the 24 hour access codes that you get when checking into an hotel?
I'd rather not try a solution such as buying another router and turning it on and setting a new password when we have guests.
