Introduction
This document provides a detailed Functional Specification for the implementation of Two-Factor Authentication (2FA) in the system named Connor. It outlines the functional requirements, data requirements, user interface requirements, and other relevant details to ensure the successful implementation of 2FA.
Purpose
The purpose of this FSD is to define the functional requirements for implementing 2FA in the Connor system. This will enhance the security of the system by requiring an additional authentication factor beyond the traditional username and password.
Scope
This FSD covers the scope of implementing 2FA in the Connor system. The implementation will involve modifying the existing login process to include an additional authentication step using a secondary factor.
Definitions, Acronyms, and Abbreviations
- 2FA: Two-Factor Authentication
- OTP: One-Time Password
- SMS: Short Message Service
- Email: Electronic Mail

Overview
The goal of this project is to enhance the security of the Connor system by implementing 2FA. The system will require users to provide an additional authentication factor, such as an OTP sent via SMS or email, in addition to their password.
Functional Requirements
Requirement 1: Implement 2FA
- ID: FR-001
- Description: Implement Two-Factor Authentication (2FA) for the Connor system to enhance user account security.
- Priority: High
- Source: Internal security team
- Rationale: To mitigate the risk of unauthorized access by adding an extra layer of security.
- Acceptance Criteria:
- Users must be prompted to enter an OTP after entering their username and password.
- OTP can be sent via SMS or email based on user preference.
- Users must be able to configure their preferred 2FA method in their account settings.
- The system must validate the OTP before granting access.
- Dependencies: Integration with SMS and email service providers.
Data Requirements
- User Data: Must include fields to store the user's preferred 2FA method (SMS or email) and contact information (phone number or email address).
- OTP Data: Must be generated, stored temporarily, and validated within a short time frame (e.g., 5 minutes).
User Interface Requirements
- Login Page: Must include an additional input field for OTP after the user enters their username and password.
- Account Settings Page: Must allow users to configure their preferred 2FA method and update their contact information.
Non-Functional Requirements
- Performance: The OTP generation and validation process must be completed within 2 seconds.
- Security: OTPs must be randomly generated and expire after a short time frame (e.g., 5 minutes).
- Usability: The 2FA process must be user-friendly and not overly complex.
Assumptions
- Users have access to either SMS or email to receive OTPs.
- Existing user data is accurate and up-to-date.
Constraints
- The system must integrate with existing SMS and email service providers.
- Implementation must not disrupt the existing login process for users who have not yet configured 2FA.
Acceptance Criteria
- The 2FA feature must be fully functional and integrated into the Connor system.
- Users must be able to successfully configure their preferred 2FA method.
- The OTP validation process must work correctly, granting access only when the correct OTP is provided.
Appendix
- Mockups of the updated login page and account settings page (if available).
- Diagrams illustrating the 2FA process flow.
