6. ACKNOWLEDGEMENT
I am equally grateful to my teacher R.K.Upadhyay. He gave me moral
support and guided me in different matters regarding the topic. He had
been very kind and patient while suggesting me the outlines of this project
and correcting my doubts. I thank his for her overall support.
Last but not the least, I would like to thank my parents who helped me a
lot in gathering different information, collecting data and guiding me
from time to time in making this project. Despite their busy schedules,
they gave me different ideas in making this project unique.
Thank you !

8. PURPOSE
Do you want to keep your money and your identity safe? Do you worry
about getting hacked or having your identity stolen? Let’s have some
real talk about passwords, and just how important they are to your
online security.
If you’re already using a password manager and have strong, unique
passwords for all of your online accounts, then job well done! You’re
likely already following all of the below advice. But you may want to
share this information with friends or family who are wondering how
they too can improve their online security, stop struggling with
passwords, and decide whether a password manager is right for them.

9. This Project aim at developing software that can be used for securing
their email id’s and passwords. This project is useful because we
generally forget our either email id’s or passwords and if we note
down on a diary or any other paper anyone can watch it and misuse our
email id. So here is a solution you can your data in password management
system and to secure your passwords by creating them as global
password and with this global password you can be surely secure that
no can see your email id’s and password . It is simple and convenient
for security.
INTRODUCTION

11. We have studied the existing system in detail .
The finding our study yield various pieces of
information which are described in the
following manner . We enter all the following
details of the user :-
 Email id .
 Password

12. All this suggest that choice of a computer with
about 500MB to 1TB Hard disk and about 8 to
16MB RAM . The availability of sophisticated
programming tool is imperative and thus a
C++ is chosen to program the system .
Having done this the next step is to carefully
analysis the data , identify processing element
and design approx. data base file .

14. The importance of software design can de started with a
single word quality . Design is the place where quality is
fostered in software development . Design provides us
with representation of software that can be accessed for
quality .
System design silts at the technical kernel of the software
engineering process and is applied regardless of
development paradigm that is used. Once software
requirements have been analyzed, the software design is
first of the three technical activities – ‘design’ , ‘code’ and
‘test’, that are required to program the software.
