Authentication Methods
3.1. Password-based Authentication:
- Description: The most common form of authentication, users provide a unique password to verify their identity.
- Considerations: Passwords should be complex, stored securely, and users should be encouraged to use unique passwords.
- Description: Requires users to provide multiple forms of identification, such as a password and a temporary code sent to their mobile device.
- Advantages: Enhances security by adding an extra layer of verification, even if one factor is compromised.
- Description: Involves using unique physical or behavioral characteristics for identification, like fingerprints, facial recognition, or voice recognition.
- Considerations: Biometric data should be securely stored and processed to prevent unauthorized access.
- Description: Users are given a physical or digital token (like a security key or smart card) for authentication.
- Advantages: Provides an additional physical element that needs to be present for authentication.
3.5. OAuth Connect:
- Description: Protocols used for authentication and authorization in the context of web applications and APIs.
- Use Cases: Commonly used for delegated authorization, allowing third-party applications to access user data.
Difference between Authentication and Authorization in LLD | System Design
When building computer programs, especially when designing complex systems, it’s super important to understand two key things: authentication and authorization. Even though these words sound similar, they do different jobs to keep our systems safe.
