Does the person who scanned the QR code have access to the wifi password after the fact on their phone? From what I remember, there is no way to access saved wifi passwords, you can just modify it but can't see the stored one.
This way, if you just have them scan the QR code on your phone (and don't let them photograph it), technically you have securely given the password without them knowing it, right?

- bscphil 7y agoIf they use the most popular QR code scanner on Android [1], it shows the password in the scanner (IIRC), along with a button to connect to it. There's no acceptably secure way to give someone a WiFi password without ... giving it to them. QR codes are a simple graphical representation of text, they don't encrypt that text in any way. Sharing a password this way is not more secure than them handing you their device and you typing it in - and if you do that you should regard the other person as in possession of your password.
