Identity & Profile Management

Duende IdentityServer needs a source for user identity and profile data: the information used to authenticate users and populate claims in tokens. You choose which implementation backs this.

The following options are available, presented from most to least full-featured:

IdentityServer 8.0 and later:
User ManagementFirst-party, passwordless-first user store supporting OTP, TOTP, passkeys, external providers, roles, groups, and full lifecycle management.
ASP.NET IdentityIntegrate IdentityServer with ASP.NET Core Identity for established, well-known user management using the standard Microsoft identity stack.
CustomImplement IProfileService directly to connect IdentityServer to any user database or store. Also the extension point for customizing claims with any provider.
