JSON Web Token features and specs

• Stateless
  Since JWTs are self-contained, they do not require server-side sessions, enabling stateless authentication and reducing server memory usage.
• Scalability
  JWTs can easily be used in distributed systems and microservices architectures due to their stateless nature, facilitating horizontal scaling.
• Decentralized Issuance
  Multiple issuers can create and sign their own tokens, allowing for more decentralized and flexible authentication mechanisms.
• Performance
  JWTs eliminate the need for database lookups during authenticating requests, as the token contains all the necessary information, which can lead to performance improvements.
• Cross-domain and Mobile Compatible
  JWTs are widely supported by different platforms and can easily be used in cross-domain situations and with mobile applications.
• Security
  JWTs can be signed and optionally encrypted, ensuring the authenticity and integrity of the data they carry.

Possible disadvantages of JSON Web Token

• Size
  JWTs tend to be larger than session IDs, which can increase the amount of data transmitted during requests.
• Expiration Handling
  Managing token expiration can be complex. Once a token is issued, it remains valid until it expires or is explicitly revoked.
• No Built-in Revocation
  Unlike sessions, JWTs cannot be easily revoked server-side, making it difficult to immediately invalidate tokens without additional mechanisms.
• Security Risks
  If a JWT is intercepted or compromised, it can be used until it expires. Thus, it should be properly secured and transmitted over HTTPS.
• Token Overhead
  Embedding too much information in the token payload can lead to performance overhead and potential data exposure risks.
• Complexity
  Implementing JWT correctly requires a thorough understanding of security practices and token lifecycle management, which can add complexity to the system.

Azure Multi-Factor Authentication features and specs

• Enhanced Security
  Azure MFA adds an additional layer of security by requiring users to verify their identity through multiple methods, reducing the risk of unauthorized access.
• Flexible Authentication Options
  It supports various authentication methods such as phone calls, text messages, app notifications, and hardware tokens, providing flexibility for users.
• Integration with Microsoft Services
  Seamless integration with other Microsoft services and Azure Active Directory ensures a cohesive security solution across different Microsoft platforms.
• Compliance Support
  Helps organizations meet compliance requirements by providing an additional layer of security that is often mandated by regulations like GDPR, HIPAA, etc.
• User-friendly
  Designed to be straightforward for end-users, reducing the friction typically associated with multi-factor authentication processes.
• Conditional Access Policies
  Enables the configuration of conditional access policies to enforce MFA for specific scenarios, balancing security needs and user convenience.

Possible disadvantages of Azure Multi-Factor Authentication

• Cost
  While some features are available for free, comprehensive usage of Azure MFA can incur additional costs depending on the Azure AD licensing model.
• Setup Complexity
  Initial setup and configuration can be complex, especially for organizations without a dedicated IT team.
• Reliance on Internet Connectivity
  Most verification methods require an internet connection, which can be a drawback in environments with unstable or unreliable internet access.
• Potential User Resistance
  Some users may find the authentication process cumbersome or may resist changes to the login process, requiring additional user education and support.
• Dependency on External Devices
  Authentication methods like text messages or app notifications depend on users having access to their mobile devices, which can be problematic if a device is lost or stolen.
• Integration Challenges with Non-Microsoft Services
  While Azure MFA integrates well with Microsoft services, integration with third-party or non-Microsoft applications may require additional configuration and support.
