Introducing Machine-to-Machine (M2M) Authentication to Enable Service Accounts

Modern B2B SaaS apps don’t just serve users—they drive a growing ecosystem of automations through APIs and MCP servers.

From analytics pipelines to custom apps to AI agents, your customers rely on non-human clients to power critical workflows behind the scenes.

Most B2B apps still handle this with static API keys or shared credentials—a fragile setup that breaks when team members leave or roles change, and creates security risks that are hard to audit.

We’re fixing that with organization-scoped service accounts—for secure, persistent automation that operates independently of individual users.

Launching Service Accounts for Organization-Level Automation

With Scalekit’s new Service Accounts, you can now securely authenticate non-human clients (CLI scripts, AI agents, and custom apps) at the organization level.

Service Accounts operate independently of human users and are:

  • Persistent – continue to function as teams evolve (or team members change)
  • Scoped – access is limited to a specific organization’s resources
  • Secure – powered by short-lived, signed JWTs for auditable access

This is machine-to-machine (M2M) authentication, built for modern SaaS automation use cases.

How It Works

  1. Register a client for your customer’s organization via Scalekit’s API
  2. Specify desired scopes and configure token expiry
  3. Receive a Client ID and Client Secret from Scalekit, which you can use in your client script or AI agent
  4. The client uses these credentials to call /oauth/token and receives a JWT access token from Scalekit, containing encoded permissions and expiry
  5. Your app verifies this token, enabling secure access

Key Capabilities

  • Fully programmatic – Create and manage org-level workflows without any user dependencies
  • Organization scoped – Restrict each client’s token only to the org they belong to, no cross-tenant risk
  • Token-based authentication: Claims and scopes are embedded directly in JWT access tokens for performance and security
  • Multiple service accounts per org – Support distinct clients per organization with tailored scopes
  • Configurable token expiry: Configure token lifetimes per use case
  • Secret rotation: Rotate tokens programmatically to minimize risk
  • Token validation – Verify tokens locally for performance and uptime. Tokens can be validated efficiently using Scalekit SDKs or your own JWT libraries—no external round trips required.

Common Use Cases

  • AI assistants: Generate daily summaries of support tickets, usage stats, or incidents to fuel chatbots and copilots
  • Finance systems: Sync invoices, payment histories, or procurement records with customer-owned systems securely
  • Data pipelines: Aggregate product metrics, performance logs, or billing data across organizations with no human bottleneck
