Logto

The Management API covers users (CRUD, role assignment, MFA management), organizations (multi-tenancy primitives), applications (OIDC client management), connectors (social/enterprise IdP configuration), and audit logs. Agents can provision users, manage organization membership, configure role-based access control, and retrieve sign-in activity logs. The machine-to-machine app model provides service account credentials for agents.

Reliability for Logto Cloud is vendor-managed with standard SaaS availability. Self-hosted Logto reliability is the team's operational responsibility — Logto runs on Node.js with PostgreSQL. The identity platform is a critical path for user authentication; high-availability configuration is essential for production deployments.

Logto is a modern open-source identity platform built on OIDC, positioning itself as a developer-friendly Auth0 alternative with strong built-in support for multi-tenancy (organizations), MFA, and social login providers. Its Management API provides programmatic control over users, organizations, applications, connectors, and audit logs — enabling agents to automate identity operations that would otherwise require the admin console. Logto Cloud (hosted) and Logto OSS (self-hosted) share the same API surface.

Authentication to the Management API uses M2M (machine-to-machine) application credentials — OAuth 2.0 client credentials flow generates access tokens scoped to management operations. The M2M model is appropriate for agents as it doesn't require human interaction and supports token rotation. Logto's RBAC for M2M apps enables scoping agent access to specific management operations.

Documentation is thorough and developer-focused with clear guides for the Management API, multi-tenancy configuration, and connector setup. The M2M application documentation for service-to-service authentication is the most relevant reference for agent integration. Teams evaluating Logto versus Authentik or ZITADEL for open-source identity should compare the multi-tenancy (organizations) support, the developer experience, and the active development momentum.
