configuring-multi-factor-authentication-with-duo

configuring-multi-factor-authentication-with-duo is a skill for Claude Code, Codex from Youngmaidainon/Agent-Level-Up. It costs 92 tokens per session (1,472 once invoked), scanned A, a copy of configuring-multi-factor-authentication-with-duo, MIT.

A guide to adding Cisco Duo multi-factor authentication, which asks users for an additional proof of identity beyond a password. It covers access through web applications, VPNs, remote desktop, and SSH.

In plain words
What is it for?
Use it to deploy Duo, set adaptive access rules, check device trust, and configure phishing-resistant methods such as WebAuthn and FIDO2.
Why use it?
It makes stolen passwords less useful and can require stronger checks based on the user, device, or network.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

configuring-multi-factor-authentication-with-duo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Configuring Multi-Factor Authentication with Duo

Overview

Deploy Cisco Duo multi-factor authentication across enterprise applications, VPN, RDP, and SSH access points. This skill covers Duo integration methods, adaptive authentication policies, device trust assessment, and phishing-resistant MFA deployment aligned with NIST 800-63B AAL2/AAL3 requirements.

When to Use

  • When deploying or configuring configuring multi factor authentication with duo capabilities in your environment
  • When establishing security controls aligned to compliance requirements
  • When building or improving security architecture for this domain
  • When conducting security assessments that require this implementation

Prerequisites

  • Familiarity with identity access management concepts and tools
  • Access to a test or lab environment for safe execution
  • Python 3.8+ with required dependencies installed
  • Appropriate authorization for any testing activities

Objectives

  • Configure Duo MFA for VPN, RDP, SSH, and web applications
  • Implement adaptive access policies based on user, device, and network context
  • Deploy phishing-resistant authentication (Duo Verified Push, WebAuthn)
  • Configure device health policies (trusted endpoints, OS version enforcement)
  • Set up Duo Admin Panel monitoring and reporting
  • Implement MFA bypass and emergency access procedures

Key Concepts

Duo Authentication Methods (by security strength)

  1. Security Keys (WebAuthn/FIDO2): Phishing-resistant, AAL3 capable
  2. Duo Verified Push: Requires code entry, resistant to MFA fatigue attacks
  3. Duo Push: Push notification to Duo Mobile app
  4. TOTP (Duo Mobile Passcode): Time-based one-time password
  5. Hardware Tokens: OTP from physical token
  6. SMS/Phone Call: Least secure, use only as fallback

Duo Integration Architecture

  • Duo Authentication Proxy: On-premises proxy for RADIUS/LDAP integration
  • Duo Web SDK: Embed Duo MFA in web applications
  • Duo OIDC/SAML: SSO integration for cloud applications
  • Duo for RDP: Windows Logon MFA
  • Duo Unix: PAM-based MFA for SSH

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
