Custom Identity Systems
Custom Identity Systems refer to bespoke solutions for managing user authentication, authorization, and identity data, typically built in-house rather than using off-the-shelf identity providers. These systems handle core identity functions like user registration, login, password management, role-based access control, and session management. They are often integrated with an organization's specific business logic, data models, and security requirements.
Developers should learn about custom identity systems when working in environments with unique compliance needs, legacy infrastructure, or specialized user management workflows that standard solutions cannot accommodate. They are particularly relevant for large enterprises, government agencies, or applications requiring granular control over identity data, such as in healthcare, finance, or custom B2B platforms. Understanding this concept helps in designing secure, scalable authentication mechanisms tailored to specific organizational constraints.
