IdentityServer features and specs

  • Open Source Foundation
    IdentityServer is built on an open-source foundation. It has been widely used and developed by a community, ensuring transparency, reliability, and continuous improvements.
  • Comprehensive Protocol Support
    It supports industry standards such as OpenID Connect and OAuth 2.0, which are essential for authentication and authorization processes.
  • Customizability

Possible disadvantages of IdentityServer

  • Licensing Cost
    Since its transition from IdentityServer4 to a non-OSS model under Duende Software, organizations need to purchase a license for commercial use, impacting budget-conscious projects.
  • Complexity
    Can be complex to set up and configure properly, especially for teams that are new to security protocols like OAuth and OpenID Connect.
  • Maintenance Overhead
    Requires ongoing maintenance and updates to ensure security and compatibility with evolving protocols, which can be resource-intensive.
  • Potential Overhead for Small Projects
    May be overkill for smaller projects or teams that do not require robust authentication systems, where simpler solutions might suffice.
  • Community vs. Commercial Transition
    The switch from a community-driven open-source project to a commercial product may alienate previous users who relied on its open-source nature.
