Introduction
This document provides a detailed specification of the functional requirements for the "Implement 2FA" project. The purpose of this project is to enhance the security of user accounts by adding a Two-Factor Authentication (2FA) mechanism.
Purpose
The purpose of this Functional Specification Document (FSD) is to outline the functional requirements necessary to implement Two-Factor Authentication (2FA). This document serves as a guide for the development and implementation of the 2FA feature.
Scope
This FSD covers the implementation of Two-Factor Authentication (2FA) for the existing user authentication system. The scope includes all necessary functional requirements, data requirements, user interface requirements, and non-functional requirements.
Definitions, Acronyms, and Abbreviations
- 2FA: Two-Factor Authentication
- OTP: One-Time Password
- UI: User Interface

Overview
The goal of this project is to implement a Two-Factor Authentication (2FA) mechanism to enhance the security of user accounts. Users will be required to provide an additional verification factor, such as a One-Time Password (OTP), in addition to their regular password.
Functional Requirements
Requirement 1: Two-Factor Authentication (2FA)
- ID: FR-001
- Description: Implement a Two-Factor Authentication (2FA) mechanism to enhance user account security. Users will be required to enter an OTP sent to their registered email or mobile device in addition to their password.
- Priority: High
- Source: Security Policy Review
- Rationale: To provide an additional layer of security to user accounts and protect against unauthorized access.
- Acceptance Criteria:
- The system must generate and send an OTP to the user's registered email or mobile device upon login attempt.
- The user must enter the correct OTP to complete the login process.
- The OTP must expire after a certain period (e.g., 5 minutes).
- The system must allow users to request a new OTP if the original one expires or is not received.
- The system must log all 2FA attempts and outcomes for security audits.
- Dependencies: Existing user authentication system, email/SMS gateway for OTP delivery.
Data Requirements
- User Data: User's registered email address or mobile number.
- OTP Data: Generated OTP, expiry time, and status (used/unused).
User Interface Requirements
- The login page must include a field for OTP entry.
- The system must provide a mechanism for users to request a new OTP.
- Error messages must be displayed for incorrect OTP entries or expired OTPs.
Non-Functional Requirements
- Performance: The OTP generation and delivery process must be completed within 5 seconds.
- Security: The OTP must be securely transmitted and stored using encryption.
- Usability: The 2FA process must be user-friendly and clearly instruct users on the steps to complete the authentication.
Assumptions
- Users have access to their registered email or mobile device to receive OTPs.
- The email/SMS gateway is reliable and has minimal downtime.
Constraints
- The implementation must be compatible with the existing authentication system.
- The project must comply with company security policies and industry standards.
Acceptance Criteria
- The 2FA feature must pass all functional and non-functional tests.
- The system must be able to handle peak loads without significant performance degradation.
- All security and usability requirements must be met.
Appendix
- None at this time.
