I don't know the passcode to install Qustodio for iOS
Qustodio does not require a passcode during the installation process. If you are asked for a passcode during the installation, this is the passcode of your device, which is the code you have set to protect your device with Apple when you first set it up. This code is not related to Qustodio.
If you forgot the passcode for your device, or your device is disabled, you entered the wrong passcode in to an iOS device six times in a row, and you're locked out. To recover the passcode for your iPhone, iPad or iPod, follow these instructions.
