We all know that a decent Wi-Fi network is password protected and to enter it on the iPhone just go to the settings, to the “ Wi-Fi ” section and search for the network we want to enter. But knowing that some of these passwords can be long and complicated, iOS has a few tricks up its sleeve for you. we can enter these Wi-Fi without having to use this password
QR codes, iCloud or friends with iPhone: one of these three factors does the magic
The first of these methods is to use the camera and a QR code. Some operators already put this code with the credentials of the Wi-Fi network directly into the router itself, so we only have to open the Camera app and focus on this QR code to be able to access the network.
If you want to take advantage of this feature and you don’t have this QR code on your router, remember that you can generate your own by following this tutorial. It takes less than five minutes, so you don’t have to reveal your password to anyone.
Another way to be able to access a Wi-Fi network without entering your password is ask someone with an iPhone to share it with you. As we told you in its time, you need someone to be connected to the network and their iPhone to be unlocked. If so, all you need to do is go to Settings> Wi-Fi and select the network you want to enter. Your friend will see a dialog that will offer to share the password with you without having to know or type it.
Also, keep in mind that your iPhone will automatically connect to a protected Wi-Fi network if another Apple device you’ve already done so before. Password is shared by iCloud, and the iPhone will charge it even if it is the first time to connect to this network. Quick and easy.
