Introduction

This document provides a detailed specification for the implementation of Two-Factor Authentication (2FA) in the My Super 2FA Project. It outlines the functional requirements, data requirements, user interface requirements, non-functional requirements, assumptions, constraints, acceptance criteria, and the approval process.

Purpose

The purpose of this FSD is to ensure that all stakeholders have a clear understanding of the functionality and requirements for implementing 2FA in the My Super 2FA Project. This document will serve as a guide for the development and testing phases.

Scope

The scope of this FSD includes the implementation of Two-Factor Authentication (2FA) for the My Super 2FA Project. This includes all necessary changes to the authentication process to incorporate a second factor for enhanced security.

Overview

The My Super 2FA Project aims to enhance the security of user authentication by implementing Two-Factor Authentication (2FA). This involves requiring users to provide two forms of identification before granting access to their accounts.

Functional Requirements

Requirement 1: Implement 2FA

• ID: FR-001
• Description: Implement Two-Factor Authentication (2FA) for user login. Users must provide a second form of verification in addition to their password.
• Priority: High
• Source: Security team
• Rationale: To enhance security and protect user accounts from unauthorized access.
• Acceptance Criteria: Users are prompted for a second form of verification (e.g., SMS code, email code, authenticator app) after entering their password. The system must verify the second factor before granting access.
• Dependencies: Integration with third-party authentication services (e.g., Google Authenticator, Twilio for SMS).

Data Requirements

• User account data, including phone numbers and email addresses for receiving 2FA codes.
• Storage of 2FA configuration settings for each user.

User Interface Requirements

• A login screen prompting for a username and password.
• A subsequent screen prompting for the second factor of authentication.
• Error messages for incorrect password or 2FA code entries.

Non-Functional Requirements

• Performance: The 2FA process should not add more than 2 seconds to the overall login time.
• Security: The system must securely transmit and store 2FA codes.
• Usability: The 2FA process should be user-friendly and provide clear instructions.

Assumptions

• Users have access to a second form of verification (e.g., mobile phone, email, authenticator app).
• The system can integrate with external 2FA providers.

Constraints

• Limited budget for integrating premium third-party 2FA services.
• The 2FA implementation must comply with relevant data protection regulations.

Acceptance Criteria

• Successful implementation and testing of the 2FA feature.
• User feedback indicates ease of use and satisfaction with the 2FA process.
• No significant increase in login time or user complaints.
