Storage Providers

Duende IdentityServer abstracts data access behind store interfaces. You choose which provider backs those interfaces.

Entity Framework CoreUse any EF Core-supported database (SQL Server, PostgreSQL, SQLite, and more) for durable, production-ready storage.
In-MemoryKeep all data in application memory. Ideal for development, testing, and simple scenarios where durability is not required.
CustomImplement the store interfaces yourself to use any database, storage backend, or data access technology.
