Headless sign-in
Authenticate users via voice, CLI, or agents without browser redirects using secure token flows.
Agent-first identity layer for voice, headless, and autonomous AI
Plug-and-play authentication and authorization for AI agents and autonomous workloads, with real-time policy enforcement, mTLS-first transport, and auditable access.

AuthSec enables you to Secure AI Agents and Users
Authentication and Authorization for Users and AI agents with modern identity primitives
Delegate trust
Users grant scoped, expiring permissions so agents can safely act on their behalf.
Agent & workload identity
Use SPIFFE, mTLS, and rotation to secure machine-to-machine communication.
Key Features
Dual Plane - AI Agents + User Identity Security
Secure users and autonomous workloads with the same policy engine, observability, and controls. No more parallel auth stacks.
OAuth2.1 for User Authentication
Native OAuth2.1 support with Authorization Code + PKCE. Issue short-lived, user-bound tokens without building custom auth flows.
User-first security · PKCE by default · Risk-based MFA
Enterprise-grade security powered by OAuth2.1 & SPIFFE
AuthSec assigns AI agents and MCP servers cryptographically verifiable identities using X.509 certificates, exchanged for short-lived, call-specific JWTs to minimize blast radius.

Workload Identity
Each agent is issued a unique X.509 workload identity (SPIFFE SVID) at startup.
Certificate-Based Authentication
Autonomous workloads authenticate using short-lived X.509 certificates.
mTLS with Automatic Rotation
Agents authenticate using mTLS with automatically rotated certificates.
Root CA & Vault-Backed PKI
HashiCorp Vault backs PKI issuance and rotation from a trusted Root CA.
From Developer to Enterprise
Get started in minutes, and scale to your enterprise needs along the way.
Single Sign-On (SSO)
Users can log in using the identity systems their company already uses. Connect with Google, Microsoft, Okta, and other enterprise SSO providers seamlessly.
Federated Authentication
Large organizations can authenticate users through their own enterprise directories. Delegate to Active Directory, Entra ID, or any SAML-compliant provider.
Authentication & Authorization Logging
Every access event is logged so enterprises can audit, monitor, and stay compliant. Track both human users and machine identities in immutable audit trails.
Role-Based Access Control (RBAC)
Who can do what is controlled through roles — across users, admins, and services. Define fine-grained permissions for both human and workload identities.
How AuthSec works ?
A unified authentication and authorization platform for MCP Servers and AI Agents
Step 1
Set up user authentication (OAuth 2.1)
Configure user authentication using OAuth 2.1 with your existing identity provider. Support for WebAuthn and FIDO-based MFA is inherited from the IdP.
- OpenID Connect (OIDC) compliant OAuth 2.1 flows
- Built-in support for enterprise identity providers
- WebAuthn & FIDO-based MFA support
- Token-based secure sessions
SDK Setup
import { AuthSec } from "@authsec/sdk"
// Initialize with one line
const auth = new AuthSec({
clientId: "client_123",
redirectUri: ".../callback",
})
Step 2
Integrate MCP servers and agents
Integrate authentication and authorization into your MCP servers and AI agents using lightweight SDKs.
- Secure SDKs for MCP servers
- AI agent identity & session management
- Token-based access to tools and APIs
- Works across distributed agent systems

SSO Logins↑ 12%

Step 3
Secure services & enforce access
Define how MCP servers and AI agents securely access external services using authenticated identities and role-based permissions.
- Cryptographic secret storage (no long-lived API keys)
- Role-based access control (RBAC)
- Scoped and expiring permissions
- Works across internal & external resources
