Setup snapshot

git clone https://github.com/ryancnelson/otp-challenger.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

OTP Identity Challenge Skill

Challenge users for fresh two-factor authentication before sensitive actions.

When to Use

Require OTP verification before:

Deploy commands (kubectl apply, terraform apply)
Financial operations (transfers, payment approvals)
Data access (PII exports, customer data)
Admin operations (user modifications, permission changes)

Scripts

verify.sh

Verify a user's OTP code and record verification state.

./verify.sh <user_id> <code>

Parameters:

user_id - Identifier for the user (e.g., email, username)
code - Either 6-digit TOTP or 44-character YubiKey OTP

Exit codes:

0 - Verification successful
1 - Invalid code or rate limited
2 - Configuration error (missing secret, invalid format)

Output on success:

✅ OTP verified for <user_id> (valid for 24 hours)
✅ YubiKey verified for <user_id> (valid for 24 hours)

Output on failure:

❌ Invalid OTP code
❌ Too many attempts. Try again in X minutes.
❌ Invalid code format. Expected 6-digit TOTP or 44-character YubiKey OTP.

check-status.sh

Check if a user's verification is still valid.

./check-status.sh <user_id>

Exit codes:

0 - User has valid (non-expired) verification
1 - User not verified or verification expired

Output:

✅ Valid for 23 more hours
⚠️ Expired 2 hours ago
❌ Never verified

generate-secret.sh

Generate a new TOTP secret with QR code (requires qrencode to be installed).

./generate-secret.sh <account_name>

Usage Pattern

#!/bin/bash
source ../otp/verify.sh

if ! verify_otp "$USER_ID" "$OTP_CODE"; then
  echo "🔒 This action requires OTP verification"
  exit 1
fi

# Proceed with sensitive action

Configuration

Required for TOTP:

OTP_SECRET - Base32 TOTP secret

Required for YubiKey:

YUBIKEY_CLIENT_ID - Yubico API client ID
YUBIKEY_SECRET_KEY - Yubico API secret key (base64)

Optional:

OTP_INTERVAL_HOURS - Verification expiry (default: 24)
OTP_MAX_FAILURES - Failed attempts before rate limiting (default: 3)
OTP_STATE_FILE - State file path (default: memory/otp-state.json)

Configuration can be set via environment variables or in ~/.openclaw/config.yaml:

security:
  otp:
    secret: "BASE32_SECRET"
  yubikey:
    clientId: "12345"
    secretKey: "base64secret"

Code Format Detection

The script auto-detects code type:

6 digits (123456) → TOTP validation
44 ModHex characters (cccccc...) → YubiKey validation

ModHex alphabet: cbdefghijklnrtuv

State File

Verification state stored in memory/otp-state.json. Contains only timestamps, no secrets.
