Secure machine-to-machine authentication & authorization
M2M (Machine-to-Machine) authentication and authorization work together to provide a complete security framework for automated system-to-system communication. Logto machine-to-machine (M2M) applications adopt the Client Credentials Flow.
Secure APIs and services communication
Logto secures your API communications and service integrations with machine-to-machine (M2M) authentication for real-world use cases.

IoT device communication
What you can do with Logto’s machine-to-machine?
Explore practical ways to leverage Logto’s M2M capabilities to connect trusted services, secure API access, and enable automated workflows.
Use M2M to securely authenticate non-human apps
Non-interactive apps can securely access the target API using the M2M flow:
- App sends App ID and App Secret to Logto
- Logto verifies them
- Logto issues an access token
- App uses the token to call the API; API validates and grants access.
Access Logto Management API with machine-to-machine
For accessing Logto Management API, you would use M2M authentication with Client Credentials Flow for operations like,
- Automated user provisioning
- Bulk user updates
- Automated role assignments
- System monitoring and analytics
Machine-to-machine authorization
Role-based access control extends to machine-to-machine applications, ensuring devices can only access functions relevant to their assigned roles.
- Application backend service
- Command line interfaces
- Hardware and IoT devices
Multi-tenant SaaS
M2M supports organization-level isolation, enabling secure service-to-service communication in multi-tenant environments.
- M2M apps can be assigned to specific organizations
- Apps can have different roles per organization (e.g. Analytics reader in Org A, Notification sender in Org B)
- Organization-level isolation prevents cross-tenant access, even for backend services
