OAuth2 features and specs

• Delegated Access
  OAuth2 allows users to grant third-party applications limited access to their resources without sharing their credentials.
• Enhanced Security
  By using access tokens with defined scopes and expiration times, OAuth2 reduces the risk of exposing user credentials and allows precise control over resource access.
• Scalability
  OAuth2 is suitable for a wide range of applications, from mobile and web apps to connected devices, allowing seamless integration across platforms.
• User Experience
  OAuth2 enhances user experience by enabling single sign-on (SSO) capabilities, allowing users to authenticate across multiple services with a single set of credentials.

Possible disadvantages of OAuth2

• Complex Implementation
  Implementing OAuth2 can be complex, especially for developers new to the protocol, as it involves understanding various flows, token management, and security considerations.
• Security Challenges
  If not implemented correctly, OAuth2 can introduce security vulnerabilities, such as authorization code interception, token leakage, or improper redirect URI handling.
• Fragmentation
  The OAuth2 specification allows for a lot of flexibility, which can lead to fragmentation and inconsistent implementations across different providers.
• Token Management
  OAuth2 requires careful management of tokens, including their expiration, revocation, and storage, which can add complexity to application development.

Django REST framework JWT features and specs

• Ease of Use
  Django REST framework JWT is straightforward to set up and integrate with existing Django REST APIs, offering a simple solution for authentication.
• Stateless Authentication
  JWT allows for stateless authentication, meaning the server does not need to store session information, reducing overhead and improving scalability.
• Wide Adoption
  As JWT is widely used in the industry, it benefits from extensive documentation and community support, making it easier to find resources and troubleshoot issues.
• Token-Based Security
  The library supports token-based authentication, enhancing security by allowing tokens to expire and be refreshed, thus reducing risks associated with stolen tokens.
• Flexibility
  JWT tokens are flexible and can include custom claims, allowing developers to embed additional user information that might be necessary for authorization.

Possible disadvantages of Django REST framework JWT

• Stateless Limitations
  Since JWT is stateless, token invalidation becomes complex, as it's difficult to instantly revoke a token without implementing additional mechanisms like token blacklisting.
• Size of Tokens
  JWTs can become relatively large, especially when carrying a lot of claims, which can lead to performance issues in terms of storage and transmission time.
• Security Concerns
  If not configured properly, JWT can be susceptible to attacks such as signing using weak algorithms, making it crucial to ensure strong cryptographic practices are followed.
• Maintenance
  The library is community-maintained and might not receive regular updates, potentially leading to compatibility issues with newer versions of dependencies or security vulnerabilities.
• Overhead in Setup
  While the basic setup is simple, implementing advanced features like token refresh and rotation requires additional configuration and code.
