The Problem
Traditional OAuth systems were designed for humans, not AI agents
Current Authentication
AI agents trying to access websites face a dilemma: they need to either use human credentials (insecure and violates ToS) or have no way to authenticate at all. There's no standard way for AI agents to prove their identity.
For Developers
Website owners want to support AI agents, but there's no standard protocol. Building custom authentication for each AI agent is time-consuming, insecure, and doesn't scale.
The Solution
Auth-Agent brings OAuth 2.1 to AI agents with their own credentials
For AI Agents
Get your own agent_id and agent_secret credentials.
Authenticate programmatically across any website that supports Auth-Agent—no human interaction needed.
For Developers
Integrate standard OAuth 2.1 with PKCE—register a client, configure redirect URIs, and handle the authorization flow.
Same process as Google or GitHub sign-in. Get JWT tokens with agent identity and start building.
Same Standard
OAuth 2.1 with PKCE and OpenID Connect (OIDC).
The proven security standard used by Google, Microsoft, and GitHub. Now available for AI agents.
How It Works
Three simple steps to enable AI agent authentication
Developer Integrates OAuth
Website developers integrate Auth Agent using standard OAuth 2.1 flow—register a client, configure redirect URIs, and handle the authorization callback. Same process as Google or GitHub OAuth.
AI Agent Gets Credentials
AI agents register once and receive their unique agent_id and agent_secret credentials.
Automated Authentication
When the AI agent encounters the Auth-Agent button, it authenticates programmatically using its credentials—no human needed!
What is Auth-Agent?
It's Sign in with Google, but for web agents and computer-using agents that act like humans.
OAuth 2.1
Latest OAuth specification with mandatory PKCE, enhanced security, and simplified flow
OIDC Compliant
OpenID Connect with ID tokens, UserInfo endpoint, and discovery document
Production-Ready
Rate limiting, token refresh, security headers, and comprehensive error handling
For AI Agents
Authenticate with any website using our Python SDK
AI Agent Authentication with Browser-Use
Enable your AI agents to authenticate on any website using our Auth Agent tools. The example shows a complete browser-use integration where an AI agent navigates to a website, clicks the "Sign in with Auth Agent" button, and completes the OAuth flow automatically.
- Programmatic authentication flow
- Browser automation with browser-use
- Secure credential verification (PBKDF2)
- Auto-redirect after authentication

Why OAuth 2.1?
Industry Standard
Same protocol as Google, GitHub, and Microsoft. No proprietary implementations.
PKCE Mandatory
Proof Key for Code Exchange prevents authorization code interception attacks.
OIDC Support
ID tokens with JWT, UserInfo endpoint, and OpenID Connect discovery.
