I attempt and dare to solve the problem of password-stealing which occur primarily due to Social Engineering Hacks. Also, this adds another layer of protection over passwords and make passwords more secure and usable!
The method exploits the fact that given a word to type, different people will type the word in different fashions. The speed of typing will be different and the typing-accent will vary. We now attach this typing-accent attribute to the password and make them more secure i.e. even if you tell your password to a third-person, he wont be able to authenticate himself as you.
Also, this improves the usability of passwords. As pointed by Jakob Nielsen, un-masking the password would provide better usability. Passwords can now be unmasked as this method tries to cover for the social engineering hacks which are the clear threats to unmasking passwords.
