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.

sso features and specs

• Convenience
  Single Sign-On (SSO) allows users to log in once and gain access to all connected systems without needing to log in again. This reduces the need to remember multiple passwords and streamlines the login process.
• Improved Security
  Centralized authentication allows for stronger security protocols to be applied consistently across all applications. It can reduce the chances of weak passwords being used and simplify the implementation of complex security measures.
• Efficient User Management
  SSO simplifies the process of user management for IT departments. It allows for centralized deprovisioning of access rights, which improves the ease of managing users in an organization.
• Reduced IT Costs
  By reducing the number of password-related helpdesk calls and streamlining user access management, SSO can lead to lower IT support costs.

Possible disadvantages of sso

• Single Point of Failure
  If the SSO system goes down, users may be unable to access all applications that rely on it. Ensuring high availability and robust disaster recovery mechanisms is essential.
• Complex Implementation
  Setting up SSO can be complex, involving significant initial setup, configuration, and testing time. It may require expertise in identity management and integration across various systems.
• Security Risk if Compromised
  If an SSO account is compromised, the attacker potentially gains access to all connected services. Strong authentication methods and continuous monitoring are critical to mitigating this risk.
• Vendor Lock-In
  Organizations may become dependent on a particular SSO provider's system, which can make future changes or migrations challenging.
