Hey there, i'm not sure if this the right section but does anyone know a way to find out a school's WiFi password? I got the password last year from a friend but now school's starting back up and I don't know if the admins change the password every school year. I have an iOS and Android device would any of these have any applications that would reveal the password or can this only be done with a computer? I'd prefer WiFi over mobile data of course so any help would be appreciated!
