Passkeys 360°
Passkeys for Every Surface
Unified Security for Apps & Agents
No passwords. No shared secrets. One phishing-resistant, device-bound credential.For AI agents, passkeys power Just-In-Time Authorization inside the conversation, backed by cryptographic proof.
Universal Coverage
One Credential. Every Surface.
Passkeys eliminate passwords across all authentication contexts: from user-facing apps to AI agents running in terminals.
Web App
Passkeys Autofill in browsers: users tap to sign in, no password typed.
Native App
OAuth 2.0 Native Flows: app controls each step, no browser redirect.
AI Agent (Chat)
Just-In-Time Authorization with Passkeys inline in AI Agents.
AI Agent (CLI)
Just-In-Time Authorization with Passkeys in CLI Agents.
Passkeys 360°
What Passkeys Deliver on Every Surface
The same FIDO2/WebAuthn credential: device-bound, phishing-resistant, non-replayable: adapts natively to each context.
Web App: Autofill Login
Users tap a native browser autofill prompt to authenticate. No password typed, no phishing risk. The browser handles the WebAuthn handshake transparently.
Native App: API-Native Flow
Based on OAuth 2.0 Native Flows, the app drives each authentication step without redirecting to a browser. Passkey assertion is completed inline, returning a token directly.
AI Agent (Chat): Just-In-Time Authorization with Passkeys
When a sensitive action requires elevated authentication, the MCP Server triggers a passkey challenge via MCP Elicitation. The AI assistant presents the prompt inline: the user taps, the assertion is verified, an elevated token is issued.
AI Agent (CLI): Just-In-Time Authorization with Passkeys
CLI agents like Claude Code request the passkey challenge directly in the terminal. The user taps their security key — no browser redirect, no codes to copy, no context switch. Cryptographic proof returned inline.
Primary Use Case
Passkeys for AI Agents
Just-In-Time Authorization
When an AI agent needs to perform a privileged action, redirecting to the Identity Provider is technically possible — but it breaks the user's flow entirely. With the ANA (Agent-Native Authorization) framework, passkeys are triggered natively inside the conversation or terminal: no browser redirect, no codes to copy, no context switching.
Device-bound, non-replayable assertion
Signs a challenge bound to the exact operation, not a generic session token.
Phishing-resistant by design
Can't be phished, replayed, or intercepted. The agent only receives the assertion result.
Works in any AI assistant or CLI
GitHub Copilot, Claude, OpenAI, and CLI agents like Claude Code. No proprietary lock-in.
Key insight: Device-bound passkeys sign a non-replayable assertion cryptographically bound to the exact operation: phishing-resistant JIT authorization for every agent action that matters.
Agent CLI: ANA + Passkeys JIT Authorization Flow
User
"Disable policy X in production"
AI Agent (Chat / CLI)
Calls MCP Server → AuthZEN enforces JIT
Passkey Challenge (FIDO2)
User taps security key / platform authenticator
Identity Provider

Also Available
Passkeys for Web & Native Apps
Passwordless Login
Beyond agents, passkeys bring passwordless login to browser-based and native mobile applications, using the same Identity Provider and open standards. The IA+ IAM Platform powers both flows natively, with no browser redirect for native apps.
Web App: Passkeys Autofill
Users tap the browser autofill prompt to sign in. No password typed, no redirect.
Native App: OAuth 2.0 Native Authentication + Passkeys
App controls each step via OAuth 2.0 Native Flows. Passkey challenge completed inline, no browser opened.
Powered by Keycloak Extensions
Keycloak SPI extensions add passkey autofill, native flows, and OTP/SMS support. Standards-based, no lock-in.
Key insight: The same Identity Provider issues tokens for web logins, native app sessions, and agent JIT elevation — one platform, consistent policy, every surface.
Web App: Passkeys Autofill Flow
User

Key Benefits
Why Passkeys for AI Agents, Web and Native Apps
FIDO2 passkeys are the strongest authenticator across every surface: phishing-resistant, hardware-bound, and natively interpretable by browsers, apps, and AI agents alike.
Phishing-Resistant
FIDO2 passkeys are origin-bound and cryptographically challenge-response. They cannot be phished, stolen, or replayed: even if the agent is compromised.
Device-Bound Credential
The private key never leaves the device. Every assertion is hardware-backed: from platform authenticators (Touch ID, Windows Hello) to security keys (YubiKey).
No Passwords, No Secrets
Zero passwords to leak, rotate, or manage. The agent never handles a credential: only receives the outcome of a verified challenge from the Identity Provider.
Native in CLI & Chat Agents
The FIDO2 assertion completes natively in Claude Code, GitHub Copilot, and custom agents. No browser window, no redirect, no context switch: stays inside the flow.
Cryptographic Proof Per Action
Every JIT authorization is backed by a signed assertion bound to that exact operation. The Identity Provider issues a context-specific elevated token: not a generic session.
Open Standard: FIDO2 / WebAuthn
Built on FIDO2 and WebAuthn: open standards supported by every major platform, browser, and identity provider. No vendor lock-in.
