mfa-implementation SKILL.md skillA
mfa-implementation from hermeticormus/libresecops-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hermeticormus/libresecops-claude-code/mfa-implementation@git:20260930.71a2663Pins git:20260930.71a2663 in mdr.lock. Pin the fingerprint instead.

MFA reference covering factor types, NIST AAL levels, WebAuthn/FIDO2 registration, TOTP implementation, enforcement middleware with step-up auth, and bypass risks such as SMS SIM swap and prompt bombing. Use when adding or hardening multi-factor authentication.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MFA Implementation > MFA methods, integration patterns, bypass prevention, and phishing-resistant authentication. ## Knowledge Base ### MFA Factor Categories Authentication factors fall into three categories (something you know, have, are): | Category | Examples | Strength | Attack Vectors | |----------|----------|----------|----------------| | **Knowledge** (something you know) | Password, PIN, security questions | Weakest alone | Phishing, credential stuffing, brute force, social engineering | | **Possession** (something you have) | TOTP app, hardware key, phone, smart card | Strong | Theft, SIM swap (SMS), real-time phishing relay | | **Inherence** (something you are) | Fingerprint, face recognition, voice | Strong (local) | Biometric spoofing, coercion, liveness detection bypass | True MFA requires factors from at least two different categories. Password + security questions is NOT MFA (both are knowledge). Password + TOTP IS MFA (knowledge + possession). ### MFA Method Comparison | Method | Phishing Resistant | User Experience | Implementation Complexity | Cost | |--------|-------------------|-----------------|--------------------------|------| …

How to install
mdr add hermeticormus/libresecops-claude-code/mfa-implementation@sha256:f1858ebbab0320d3The line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
