Introduction
DEFINITION OF A PASSWORD MANAGER: IMPORTANCE OF PASSWORD MANAGERS: OVERVIEW OF FEATURES:
• A password manager is a software
application designed to store and
manage online credentials. It requires a
master password to access its vault,
which contains all other passwords.
• Its primary purpose is to provide a
secure and convenient way to store,
retrieve, and use strong, unique
passwords for various online accounts
and services.
• Password managers enhance both
security and convenience by generating
and storing strong, unique passwords
for each account, reducing the risk of
password-related breaches.
• They streamline the login process by
auto-filling credentials, saving users
time and reducing the likelihood of
phishing attacks.
Password managers come with a range of
features designed to improve user security
and ease of use. Key features typically
include:
•Secure Password Storage
•Auto-Filling Login Forms
•Password Generation:
•Cross-Device Synchronization
•Secure Notes Storage
•Two-Factor Authentication (2FA) Support
•Password Health Reports

Password Storage Encryption and decryption
Master Password Synchronization
How Password Managers Work
• Passwords are securely stored in a database using
hashing and encryption techniques.
• Each password is transformed into a hashed format
with a unique salt, ensuring that even if the
database is breached, the passwords remain
protected.
• Passwords are encrypted using robust algorithms
like AES-256 before storage.
• The encryption process converts passwords into
cipher text, which can only be decrypted with a
specific key, ensuring secure access.
• The master password serves as the single key
to access the entire password manager.
• It is the only password the user needs to
remember and is used to unlock the encrypted
vault of stored passwords.
• Password managers use end-to-end encryption
to synchronize passwords across multiple
devices.
• Passwords are encrypted on the user's device
before being transmitted and can only be
decrypted on the user's other devices, ensuring
security during transmission.

Hashing Functions for Passwords
Purpose Of Hashing
• Hashing is used in password Hashing
transforms passwords into fixed-
length, irreversible strings.
• It enhances security by making stored
passwords difficult to decipher if the
database is compromised.
Common Hashing Algorithms
• SHA-256: Offers a good balance of
security and speed.
• bcrypt: Includes a salt to defend
against rainbow table attacks.
• Argon2: Known for its resistance to
side-channel attacks and customizable
memory usage.
Choosing A Hashing Function
• Consider security strength,
performance efficiency, and resistance
to attacks.
• Prefer functions like bcrypt or Argon2
for strong protection against brute
force and rainbow table attacks.
Implementation of Hashing
•Passwords are hashed using a secure
algorithm before storage.
•code example:
•import bcrypt
•hashed_password=bcrypt.hashpw(pass
word.encode('utf-8'), bcrypt.gensalt())
Storing Hashed Passwords
• Store hashed passwords with a unique
salt for each password.
• Ensures even identical passwords have
unique hashes, enhancing security.
Verifying Password
• Hash the input password using the
same algorithm and compare it to the
stored hash.
• Authentication is successful if the
hashes match, allowing secure access.

How Does MFA Work?
1. Knowledge Factor: Something the user knows like master
password.
2. Possession Factor: Something the user has.
3. Inherence Factor: Something the user is.
Why MFA?
Enhances security by combining two or more independent
credentials.
What the user knows (password).
What the user has (security token).
What the user is (biometric verification).
Protects against phishing, social engineering, and password
brute-force attacks.
Secures login sessions from attackers exploiting weak or stolen
credentials..
Multi-Factor Authentication (MFA) adds an additional layer of security to the password management system by requiring users to
provide multiple forms of identification before accessing their accounts.
Benefits
• Enhanced Security: Reduces the risk of unauthorized access
even if the master password is compromised.
• User Verification: Ensures the person attempting to access the
password manager is the authorized user.
• Compliance: Helps meet security standards and regulations for
data protection.
Multi-Factor Authentication (MFA)

To create and manage the database, SQL commands such as
CREATE TABLE and INSERT are used. .
SQL Commands:
The database structure includes key tables such as the Users table and the
Passwords table. The Users table stores user information, while the
Passwords table contains fields like site/app name, URL, and hashed
passwords. Each entry in the Passwords table is linked to a user, ensuring
organized and secure storage.
Database Schema:
Additional security measures for the database include encrypting
sensitive data and implementing strict access controls. Encrypting the
database content ensures that even if unauthorized access occurs,
the data remains unreadable. Access controls limit database
interactions to authorized users and applications only, enhancing
overall security.
Security Measures:
Creating an SQL Database for
Password Manager
The terminal then prompts for the site name, URL,
and password. Once entered, the system confirms
the successful addition of the password.
Adding a New Password
Users interact with the password manager through text-based commands
in the terminal. The system prompts for necessary inputs, such as site
name and password, and provides immediate feedback
User Input and Output
The terminal prompts for the site name and then displays the
password or confirms it has been copied to the clipboard.
This allows users to access their stored credentials easily.

Conclusion
We have explored the fundamentals of password management systems,
including secure password storage, hashing functions, SQL database setup,
terminal interface commands, and essential security best practices. Emphasizing
strong master passwords, regular software updates, and two-factor
authentication ensures robust protection of user credentials.
