Empower your APIs and IoTs

Automate Secure Access

Let your non-interactive applications communicate securely with APIs and resources.

Granular Permissions

Assign precise scopes to each service account, ensuring every microservice or device gets only the permissions it needs.

Industry-Standard Security

Built on OAuth 2.0 client credentials flow, trusted by leading platforms for robust, token-based authorization.

Common Use Cases

Application Backends

Securely transfer data, logs, or files between internal and external services.

CLI Tools

Let command-line tools securely access APIs using short-lived, scoped tokens.

Scheduled Jobs & Daemons

Authorize cronjobs, job schedulers, and background workers to interact with APIs safely and efficiently.

IoT Devices

Enable smart devices to send data to your cloud services automatically, with each device authenticated and scoped individually.

How it Works

Add APIs to Authgear and define the scopes (permissions) for each of them

Create a client application for each backend, device, or tool that needs API access. Assign the resources and scopes available to the service

Obtain Credentials

Each application receives a unique client ID and secret

Request a Token

The application authenticates with Authgear and receives an access token, containing only the scopes you’ve assigned.

Access Protected APIs

The service uses the token to call your APIs
