Passwords have been used to log in to computer systems for the last 40 years, despite millions of leaked passwords caused by hackers attacking popular websites like LinkedIn, showing that using them is not really secure.

People want everything to be fast and simple. A solution which will be adopted by the masses has to be easier and more secure than the password login process.
