Secure Machine-to-Machine
(M2M) Auth

Secure your Machine-to-Machine (M2M) communication with short-lived tokens and
granular access control.

What is M2M authentication
and authorization?

M2M authentication secures system-to-system communication without human involvement. Instead of static keys, services use credentials to obtain short-lived tokens, enabling secure, auditable, and revocable access across APIs, microservices, and integrations.

Client
authentication

Implement the OAuth 2.0 Client Credentials flow using secrets or certificates.

Token
exchange

Bridge trust domains, dynamically adjust scopes and ensure tokens are issued exclusively for specific service using OAuth2 token exchange.

Input-constrained
devices

Use OAuth 2.0 Device Authorization Grant with input-constrained devices without compromising the user experience.

M2M Auth for APIs, CLI,
and devices

APIs and microservices
APIs and microservices

Securely transfer data from external and internal applications to APIs and microservices.

CLI and daemons
CLI and daemons

Enable command-line tools and background daemons to authorize and securely access APIs using short-lived tokens.

Input-constrained devices
Input-constrained devices

Empower input-constrained devices to securely communicate with APIs using user-authorized tokens.

M2M Auth with 
WSO2 Identity Platform

Securely connect your entire API ecosystem graphic Scope and subscriptions for precision API governance Token exchange for zero-trust communication Token exchange for adaptive just-in-time access Secure connectivity for input-constrained devices

Securely connect your entire API ecosystem

Enable first-party, third-party, and internal applications to securely communicate with APIs using scoped, short-lived tokens.

  • Authenticate using client secrets or certificates.
  • Support self-contained JWT access tokens or opaque token formats.

Scope and subscriptions for precision API governance

Attach granular scopes to each API resource and govern application subscriptions during onboarding.

Token exchange for zero-trust communication

Implement zero-trust communication across your APIs and microservices using token exchange. Each token is scoped to a specific API and application.

Token exchange for adaptive just-in-time access

Dynamically upgrade and downgrade token scopes to ensure just-in-time, least-privilege access, safeguarding your high-value resources with precision.

Secure connectivity for input-constrained devices

Extend enterprise security to input-constrained devices using OAuth 2.0 Device Code, enabling users to authenticate via a separate device. Verification codes delivered instantly via text message or email.
