Identity
Overview
The Identity Service is a crucial component of our system responsible for managing user identities and authentication processes. It provides functionality for user registration, login, authentication, and profile management. Additionally, it supports features for managing companies and inviting members.
Features
User Registration
Allows users to create new accounts by providing necessary information such as username, email, and password.
Validates user inputs to ensure data integrity and security.
Generates unique identifiers for each user.
User Authentication
Provides authentication mechanisms to verify the identity of users during login.
Supports various authentication methods including password-based authentication, token-based authentication, and OAuth.
Password Management
Implements secure password hashing and storage techniques to protect user credentials.
Allows users to reset forgotten passwords securely through email verification or security questions.
Profile Management
Enables users to manage their profiles by updating personal information, changing passwords, and configuring account settings.
Provides options for users to customize their profile settings and privacy preferences.
Company Management

Logic Replication
To ensure high availability and fault tolerance, critical components of the Identity Service implement logic replication. This involves duplicating certain logic or processes across multiple servers or instances, allowing for redundancy and failover mechanisms in case of hardware failures or system disruptions. Logic replication helps maintain system reliability and performance even under adverse conditions.
