A method for developing a password based on a biometric template via a graphical user interface (GUI). The method includes receiving a password request input by a user via the graphical user interface, receiving a passphrase input by the user and simultaneously obtaining data associated with keystroke dynamics of a user while the user inputs the passphrase, creating a biometric template based upon the data obtained and keystroke dynamics data of the user collected over a predetermined period of time, generating the password based on the biometric template created and the passphrase inputted, and displaying the generated password to the user via the graphical user interface.
