Delay before ‘Yes, log me in’ button activates when signing in with a QR code

Adding a delay before the ‘Yes, log me in’ button activates when signing in via a QR code would probably save a LOT of accounts from QR code phishing attacks, especially the ones that belong to the people who absent-mindedly tap ‘Yes’ to everything. 

To improve the effectiveness of the delay, a message could be displayed on the disabled button that tells them to read the warning above thoroughly (plus it could have a timer displaying how many seconds are left till the button activates).
