Agent Authentication, and the human behind it.

Authenticate the origin of every AI agent with Enhanced Web Bot Auth, then bind that agent to a verified human identity. Know exactly who, and what, is acting on your surface.

What is agent authentication?

Agent authentication is the process of cryptographically verifying the origin of an AI agent and binding that agent to a verified human identity before it acts on your surface. LoginID authenticates agents with Enhanced Web Bot Auth, falling back to IP and reverse-DNS checks when signatures aren't present, then links the agent session to a passkey-verified person at NIST AAL2. The result is a known, accountable actor instead of anonymous automated traffic.

Authenticate the agent. Bind the human. Trust the session.

Enhanced Web Bot Auth

Cryptographic agent authentication via Web Bot Auth, with IP and rDNS fallback when signatures aren't present.

Human Identity Linking

Bind every agent session to a passkey-verified human, so an agent never acts unattached to a real, accountable person.

Phishing-resistant by design

There is no shared secret to steal, replay, or phish, with assurance at NIST AAL2.

Portable agent credentials

Interoperate with emerging agent-identity standards so verified agent credentials travel across surfaces.

How agent authentication works.

  1. 01

    Agent presents credentials

    Incoming agent traffic is checked against Web Bot Auth signatures, with IP and rDNS fallback.

  2. 02

    Bind to a verified human

    The agent session is linked to a passkey-authenticated human identity at AAL2.

  3. 03

    Hand back a known actor

    Your app receives an authenticated agent tied to a real, accountable person, ready to authorize.

Frequently asked questions

How do AI agents authenticate to a website or API?
An AI agent authenticates by presenting verifiable credentials. LoginID checks them with Enhanced Web Bot Auth and falls back to IP and reverse-DNS signals when a signature isn't available. The agent session is then bound to a verified human, so your application receives a known actor rather than anonymous bot traffic.
What is Web Bot Auth?
Web Bot Auth is an emerging standard for cryptographically signing automated (bot/agent) HTTP traffic so servers can verify which operator an agent represents. LoginID's Enhanced Web Bot Auth adds IP and reverse-DNS fallback and binds the verified agent to an accountable human identity.
Why bind an AI agent to a human identity?
Binding an agent to a verified human establishes accountability: you know a real, identifiable person stands behind every action the agent takes. This closes the gap left by pure bot detection and supports audit, liability, and fraud-prevention requirements.
Is LoginID agent authentication phishing-resistant?
Yes. LoginID is passkey-centric, so there is no shared secret, password, or OTP to steal, replay, or phish. Authentication assurance is delivered at NIST AAL2 and is FIDO2-certified.
How long does it take to integrate?
Most teams ship phishing-resistant agent authentication in days, not quarters, using a single API integration with minimal backend changes.
