By ABHISHEK KUMAR

In this Project, a Random password can generate, add a password, retrieve stored password, and delete a stored password.

CONTENTS:-

1. Project information

2. Project Requirement

3. Details

4. Source code

5. Output

Project Information:-

This project is for how can be secure password. And also in this project We stored the password in the file. This project helps many users for storing passwords because it is difficult to remember many passwords at a single time for many websites. And also They can't use a single password for any website because it is not secure. So This project helps such users. In this Digital world Hackers will always try to break password security. So we should use more to secure longer passwords using symbols.

Project Requirement:- 

1. Import String

pip install string

2. Import Json

pip install json

Details:-

The code asks the to user write a file name in which the password is to be stored.

Password is very important for everyone. If the password leaks then our information will be leaked. so we should secure the password.

Then it will show 5 options.

1st option Generate Random Password.

2nd option Add a password

3rd option shows the Retrieve password which was saved in the file.

4th option shows to delete a saved password

5th option shows the exit option.

project source code saved with filename.py and import necessary library through cmd in windows then run python filename.py then it will show all above option. Then you will use it according to your needs.
