Database Design for Authentication System Design

Database design for authentication system:

6.1. User Table

The User Table stores user data with the following fields:

• user_id (PK): Unique identifier for each user.
• username: User’s username for authentication.
• email: User’s email address for communication.
• password: Encrypted password for user authentication.
• created_at: Timestamp indicating when the user account was created.

6.2. Credentials Table

The Credentials Table stores login credentials, including hashed passwords, with the following fields:

• credential_id (PK): Unique identifier for each credential.
• user_id (FK): Foreign key referencing the User Table.
• password_hash: Hashed password for user authentication.
• last_login: Timestamp indicating the user’s last login.

6.3. Password Table

Password table are used to store passwords set by user. It includes field like

• password_id (PK): Unique identifier for each password entry.
• user_id (FK): Foreign key referencing the User Table.
• password_hash: Hashed password for user authentication.

6.4. PasswordResetRequests Table

is used to store information related to password reset requests initiated by users. It include field like

• request_id (PK): Unique identifier for each password reset request.
• user_id (FK): Foreign key referencing the User Table.
• token_value: Value of the token for the password reset.
• expiration_time: Timestamp indicating when the password reset token expires.

6.5. Session Table

The Session Table tracks user sessions with the following fields:

• session_id (PK): Unique identifier for each session.
• user_id (FK): Foreign key referencing the User Table.
• login_time: Timestamp indicating the session login time.
• last_activity: Timestamp indicating the session’s last activity.

6.6. Token Table

The Token Table stores information about user tokens with the following fields:

• token_id (PK): Unique identifier for each token.
• user_id (FK): Foreign key referencing the User Table.
• token_value: Value of the token for authentication.
• expiration_time: Timestamp indicating when the token expires.

Keeping your important digital information safe is like building a strong foundation, and the key to that is a good security system. This article will help you understand how to make a robust security system step by step. We’ll start with figuring out what you want to protect and what you want to achieve. Then, we’ll talk about the detailed design aspects, like how the system works at both the small and big levels, the structure of the database, using smaller specialized services, and making sure the system can handle more load without slowing down.
