# 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.
```bash
./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.
```bash
./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).
```bash
./generate-secret.sh <account_name>
```
## Usage Pattern
```bash
#!/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`:
```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.
