Password-based authentication is the first of defense of most information systems. Password security enhances the
security of the whole information system. Therefore, administrators will formulate the various password strategies to help users
to improve security for authentication. To determine the password vulnerability and to enhance user privacy, strong password is
must. This paper focuses generation of strong password. Also, we enhance the traditional password generation strategy based on
Mnemonic Shape, X-Pass is proposed. X-Pass combines the characters generated by our mapping strategy to help users create a
safe and strong password. We have designed a 4x4 matrix called X-Matrix that contains all the hex-digits in it. This hex-digits is
converted to numerical digits through binary conversion and we lookup UNICODE character based on numerical digit. After,
all numerical digits are processed and returned the characters are appended and then pre-processed to remove the non-printable
characters
