WIFI PASSWORD (WEP-WPA-WPA2) is an app to generate random passwords for your WiFi network. Do keep in mind that this app doesn't let you 'hack' or 'crack' absolutely anything, but simply generate random passwords to boost the security of your WiFi network. You could indeed use it to pretend you're hacking something in front of your friends, but the truth is that all WIFI PASSWORD (WEP-WPA-WPA2) does is generate passwords.
Once you've generated a password, all you have to do is tap a button to copy the text and paste it anywhere you want. Easy, smooth, and effective.
