Developer-first identity & access

API Access Management + MFA, built to be clean and predictable.

Authin centralizes authorization for apps and APIs, adds Multi-Factor Authentication, and keeps your integration surface simple — without bloated dashboards or noisy UI.

Features

Everything here is written to look good on mobile first: consistent spacing, readable type, no clutter.

API Access Management

Centralize authorization for apps and APIs. Manage roles, scopes, and policy evaluation with a consistent model.

Multi-Factor Authentication

Fingerprint / facial on supported clients, time-based OTP, QR enrollment, step-up MFA, and recovery options.

Audit & Controls

Track critical auth events, enforce device policies, and keep a clean audit trail for admin actions.

How it works

A minimal integration flow that teams actually keep.

1) Request token

curl -s https://authin.org/oauth/token \
  -d 'client_id=YOUR_CLIENT_ID' \
  -d 'client_secret=YOUR_CLIENT_SECRET' \
  -d 'grant_type=client_credentials'

2) Call your API

curl -H "Authorization: Bearer $TOKEN" \
  https://api.yoursite.com/v1/resource

Security posture

Strong defaults. Clear boundaries. No “magic” behavior.

Least privilege

Scopes and roles designed for granular access. Start strict, open only when necessary.

Step-up MFA

Require extra verification for sensitive actions: billing, admin, new device, export, etc.

Clear error model

Consistent auth responses and codes help developers debug fast without exposing sensitive detail.
