Okay..My ? may sound TOO easy for most to all of you but to me, whom is pretty much computer illiterate.. The ? is, I had relatives over and they wanted to connect their DEVICES to my WIFI to use; and I HAD to give it out to them, 4 ppl now have my ID/PW and the ? is, is it safe?? I mean, they're using while here but once they return to their own country and NEW YORK, can they still access my network?? I know, stupid ? since I DON'T think they can; but for PEACE OF MIND, I NEED to know that ? and that they can't??? Can they also DO ANYTHING with the ID/PW while in their own country/state?? Should I change my ID/PW after they're gone???
Any help would be appreciated!!
