Introduction

This document outlines the functional specifications for the project to install Two-Factor Authentication (2FA) across all login systems.

Purpose

The purpose of this FSD is to detail the functional requirements necessary to implement 2FA for enhancing the security of our login systems.

Scope

This FSD pertains to the installation of 2FA on all login systems within our organization.

Overview

The main objective of this project is to enhance the security of our login systems by implementing 2FA. This will require users to provide two forms of authentication before gaining access to the system.

Functional Requirements

Requirement 1: Implement 2FA

• ID: FR-001
• Description: Install 2FA on all login systems to enhance security.
• Priority: High
• Source: Internal Security Policy
• Rationale: To provide an additional layer of security and protect sensitive data.
• Acceptance Criteria:
  • 2FA must be successfully integrated into all login systems.
  • Users must be able to complete the 2FA process without errors.
  • System logs must show successful and failed 2FA attempts.
• Dependencies:
  • Availability of a 2FA service provider.
  • Integration with existing authentication systems.

Data Requirements

• User credentials (username and password)
• 2FA token (e.g., OTP, biometric data)

User Interface Requirements

• Login page must include an additional field for 2FA input.
• Error messages must be displayed for failed 2FA attempts.
• Success messages must be displayed for successful 2FA completion.

Non-Functional Requirements

• Performance: The 2FA process should not add more than 2 seconds to the login time.
• Security: 2FA data must be encrypted during transmission and storage.
• Usability: The 2FA process should be easy to understand and complete for users.

Assumptions

• Users have access to a 2FA device (e.g., smartphone, security token).
• The existing authentication system can be modified to integrate 2FA.

Constraints

• 2FA implementation must comply with company security policies.
• Integration must be completed within the budget and timeframe allocated.

Acceptance Criteria

• Successful integration of 2FA on all login systems.
• No critical issues or bugs reported post-implementation.
• User feedback indicates the 2FA process is manageable.

Appendix

• Mockups of the updated login page
• Integration guidelines from the 2FA service provider
