The idstore package provides an identity server for centralized authentication.


  • Simple, centralized identity storage and password checking. Passwords are securely stored using PBKDF2.
  • Email-based password reset functionality with a minimalist web interface.
  • Full API access for all operations: Separate user-facing and administrator-facing APIs are exposed on different ports and are accessed using an efficient binary protocol over HTTP.
  • Full Java API for performing user and administrative operations.
  • Strong separation between administrators and users.
  • Fine-grained capability-based security model for administrative operations; Safely write external services that can perform administrative operations while maintaining the principle of least privilege.
  • Command-line administrative shell.
  • Complete audit log; every operation that changes the state of the system is logged in an append-only log.
  • Fully instrumented with OpenTelemetry.
  • A small, easily auditable codebase with a heavy use of modularity for correctness.
  • An extensive automated test suite with high coverage.
  • Platform independence. No platform-dependent code is included in any form, and installations can largely be carried between platforms without changes.
  • Extensive documentation including information on installation, a setup tutorial, a theory of operation, maintenance and monitoring information, information on security properties, and full API documentation.
  • OCI-ready: Ready to run as an immutable, stateless, read-only, unprivileged container for maximum security and reliability.
  • OSGi-ready.
  • JPMS-ready.
  • ISC license.
