Will AI kill the password?

'Please enter your username and password', a request so common we hardly notice it; from online shopping to online banking. In recent years we've become so accustomed to biometric logins and two-step authentication models when it comes to passwords; entering the same old user ID password that we've had for years. In fact, 89 per cent of people use the same one or two passwords for everything. But is this the optimal security option for consumers? With artificial intelligence (AI), this could all come to an end.
