Credential Manager
STATUS: MANDATORY SECURITY FOUNDATION
Consolidate scattered API keys and credentials into a secure, centralized .env file.
⚠️ This Is Not Optional
Centralized .env credential management is a core requirement for OpenClaw security. If your credentials are scattered across multiple files, stop and consolidate them now.
THE RULE: All credentials MUST be in ~/.openclaw/.env ONLY. No workspace, no skills, no scripts directories.
See:
- CORE-PRINCIPLE.md - Why this is non-negotiable
- CONSOLIDATION-RULE.md - The single source principle
The Foundation
Every OpenClaw deployment MUST have:
~/.openclaw/.env (mode 600)
This is your single source of truth for all credentials. No exceptions.
Why?
- Single location = easier to secure
- File mode 600 = only you can read
- Git-ignored = won't accidentally commit
- Validated format = catches errors
- Audit trail = know what changed
Scattered credentials = scattered attack surface. This skill fixes that.
What This Skill Does
- Scans for credentials in common locations (including deep scan for hardcoded secrets)
- Backs up existing credential files (timestamped, mode 600)
- Consolidates into
~/.openclaw/.env - Secures with proper permissions (600 files, 700 directories)
- Validates security, format, and entropy
- Encrypts high-value secrets with GPG (wallet keys, private keys, mnemonics)
- Tracks credential rotation schedules
- Enforces best practices via fail-fast checks
- Cleans up old files after migration
Detection Parameters
The skill automatically detects credentials by scanning for:
File Patterns:
~/.config/*/credentials.json— Service config directories~/.config/*/*.credentials.json— Nested credential files~/.openclaw/*.json— Credential files in OpenClaw root~/.openclaw/*-credentials*— Named credential files (e.g., farcaster-credentials.json)~/.openclaw/workspace/memory/*-creds.json— Memory credential files~/.openclaw/workspace/memory/*credentials*.json— Memory credential files~/.openclaw/workspace/.env— Workspace env files~/.openclaw/workspace/*/.env— Subdirectory env files~/.openclaw/workspace/skills/*/.env— Skill env files~/.local/share/*/credentials.json— Local share directories
Sensitive Key Patterns:
- API keys, access tokens, bearer tokens
- Secrets, passwords, passphrases
- OAuth consumer keys
- Private keys, signing keys, wallet keys
- Mnemonics and seed phrases
Deep Scan (--deep flag):
- Greps
.sh,.js,.py,.mjs,.tsfiles for hardcoded secrets - Detects high-entropy strings matching common key prefixes (
sk_,pk_,Bearer,0x+ 64 hex) - Excludes
node_modules/,.git/ - Reports file, line number, and key pattern matched
Security Checks:
- File permissions (must be
600for files,700for directories) - Backup permissions (must be
600for backup files,700for backup dirs) - Git-ignore protection
- Format validation (allows quoted values with spaces)
- Entropy analysis (flags suspiciously low-entropy secrets)
- Private key detection (flags
0x+ 64 hex char values) - Mnemonic detection (flags 12/24 word values)
- Symlink detection (validates symlinked .env targets)
Quick Start
Full Migration (Recommended)
# Scan for credentials

Common Credential Locations
The skill scans these locations:
~/.config/*/credentials.json
~/.openclaw/*.json
~/.openclaw/*-credentials*
~/.openclaw/workspace/memory/*-creds.json
~/.openclaw/workspace/memory/*credentials*.json
~/.openclaw/workspace/*/.env
~/.openclaw/workspace/skills/*/.env
~/.env (if exists, merges)
Security Features
✅ File permissions: Sets .env to mode 600 (owner only)
✅ Directory permissions: Sets backup dirs to mode 700 (owner only)
✅ Backup permissions: Sets backup files to mode 600 (owner only)
✅ Git protection: Creates/updates .gitignore
✅ Backups: Timestamped backups before changes (secured)
✅ Validation: Checks format, permissions, entropy, and duplicates
✅ Template: Creates .env.example (safe to share)
✅ GPG encryption: Encrypts high-value secrets at rest
✅ Rotation tracking: Warns when credentials need rotation
✅ Deep scan: Detects hardcoded secrets in source files
✅ Symlink-aware: Validates symlinked .env targets
Output Structure
After migration:
~/.openclaw/
├── .env # All credentials (secure, mode 600)
├── .env.secrets.gpg # GPG-encrypted high-value keys (mode 600)
├── .env.meta # Rotation metadata (mode 600)
├── .env.example # Template (safe to share)
├── .gitignore # Protects .env and .env.secrets.gpg
└── backups/ # (mode 700)
└── credentials-old-YYYYMMDD/ # (mode 700)
└── *.bak # Backup files (mode 600)
GPG Encryption for High-Value Secrets
Private keys, wallet keys, and mnemonics should never exist as plaintext on disk. Use GPG encryption for these.
Setup GPG
# First-time setup (generates OpenClaw GPG key, configures agent cache)
./scripts/setup-gpg.sh
Encrypt High-Value Keys
# Encrypt specific keys (moves them from .env to .env.secrets.gpg)
./scripts/encrypt.py --keys MAIN_WALLET_PRIVATE_KEY,CUSTODY_PRIVATE_KEY,SIGNER_PRIVATE_KEY
# The .env will contain placeholders:
# MAIN_WALLET_PRIVATE_KEY=GPG:MAIN_WALLET_PRIVATE_KEY
How Scripts Access Encrypted Keys
The enforce.py module handles this transparently:
from enforce import get_credential
# Works for both plaintext and GPG-encrypted keys
key = get_credential('MAIN_WALLET_PRIVATE_KEY')
# If value starts with "GPG:", decrypts from .env.secrets.gpg automatically
GPG Agent Caching
On headless servers (VPS), the GPG agent caches the passphrase:
- Default cache TTL: 8 hours
- Configurable via
setup-gpg.sh - Passphrase required once after reboot, then cached
What to Encrypt
| Key Type | Encrypt? | Why |
|---|---|---|
| Wallet private keys | ✅ Yes | Controls funds |
| Custody/signer private keys | ✅ Yes | Controls identity |
| Mnemonics / seed phrases | ✅ Yes | Master recovery |
| API keys (services) | ❌ No | Revocable, low damage |
| Agent IDs, names, URLs | ❌ No | Not secrets |
Credential Rotation Tracking
Setup Rotation Metadata
# Initialize rotation tracking for all keys
./scripts/rotation-check.py --init
Creates ~/.openclaw/.env.meta:
{
"MAIN_WALLET_PRIVATE_KEY": {
"created": "2026-01-15",
"lastRotated": null,
"rotationDays": 90,
"risk": "critical"
},
"MOLTBOOK_API_KEY": {
"created": "2026-02-04",
"lastRotated": null,
"rotationDays": 180,
"risk": "low"
}
}
Check Rotation Status
# Check which keys need rotation
./scripts/rotation-check.py
# Output:
# 🔴 MAIN_WALLET_PRIVATE_KEY: 26 days old (critical, rotate every 90 days)
# ✅ MOLTBOOK_API_KEY: 7 days old (low, rotate every 180 days)
Rotation Schedules
| Risk Level | Rotation Period | Examples |
|---|---|---|
| Critical | 90 days | Wallet keys, private keys |
| Standard | 180 days | API keys for paid services |
| Low | 365 days | Free-tier API keys, agent IDs |
Add to Heartbeat (Optional)
Add rotation checks to HEARTBEAT.md for periodic monitoring:
## Credential Rotation (weekly)
If 7+ days since last rotation check:
1. Run: ./scripts/rotation-check.py
2. If any keys overdue: notify human
3. Update lastRotationCheck timestamp

Migration Workflow
This is the exact step-by-step flow, tested and verified on a live OpenClaw deployment.
Step 1: Scan for Scattered Credentials
cd /path/to/openclaw/skills/credential-manager
# Basic scan — finds credential files by path patterns
./scripts/scan.py
# Deep scan — also greps source files for hardcoded secrets
./scripts/scan.py --deep
What to look for in output:
- ⚠️ files with mode != 600 (insecure permissions)
- Symlinked
.envfiles (should point to main~/.openclaw/.env) - JSON credential files outside
~/.openclaw/.env - Deep scan hits on hardcoded keys in scripts
Example output:
⚠️ /home/user/.openclaw/farcaster-credentials.json
Type: json
Keys: custodyPrivateKey, signerPrivateKey, ...
Mode: 644
⚠️ Should be 600 for security
✅ /home/user/.openclaw/.env
Type: env
Keys: API_KEY, X_CONSUMER_KEY, ...
Mode: 600
Step 2: Consolidate into .env
./scripts/consolidate.py
Interactive flow:
- Script scans and lists all credential files found
- Backs up existing
.envto~/.openclaw/backups/credentials-old-YYYYMMDD/ - Loads existing
.envkeys - Processes each credential file:
- Auto-detects service (x, farcaster, moltbook, molten, etc.)
- Normalizes key names (e.g.,
custodyPrivateKey→FARCASTER_CUSTODY_PRIVATE_KEY) - Shows mapping:
key → ENV_KEY
- Asks for confirmation:
Proceed? [y/N] - Writes merged
.env(mode 600) - Creates
.env.exampletemplate (safe to share) - Updates
.gitignore
For credentials not auto-detected (e.g., nested JSON like farcaster-credentials.json with multiple accounts), manually add to .env:
cat >> ~/.openclaw/.env << 'EOF'
# FARCASTER (Active: mr-teeclaw, FID 2700953)
FARCASTER_FID=2700953
FARCASTER_FNAME=mr-teeclaw
FARCASTER_CUSTODY_ADDRESS=0x...
FARCASTER_CUSTODY_PRIVATE_KEY=0x...
FARCASTER_SIGNER_PUBLIC_KEY=...
FARCASTER_SIGNER_PRIVATE_KEY=...
# FARCASTER LEGACY (teeclaw, FID 2684290)
FARCASTER_LEGACY_FID=2684290
FARCASTER_LEGACY_CUSTODY_ADDRESS=0x...
FARCASTER_LEGACY_CUSTODY_PRIVATE_KEY=0x...
FARCASTER_LEGACY_SIGNER_PUBLIC_KEY=...
FARCASTER_LEGACY_SIGNER_PRIVATE_KEY=...
EOF
chmod 600 ~/.openclaw/.env
Step 3: Validate
./scripts/validate.py
Checks performed:
- ✅
.envpermissions (must be 600) - ✅
.gitignorecoverage - ✅ Format validation (key format, quoting, duplicates)
- ✅ Security analysis:
- Detects plaintext private keys (
0x+ 64 hex chars) → recommends GPG - Detects mnemonic/seed phrases (12/24 word values) → recommends GPG
- Entropy analysis on SECRET/PRIVATE_KEY/PASSWORD fields
- Flags weak/placeholder values
- Detects plaintext private keys (
- ✅ Backup permissions (files must be 600, directories 700)
Fix issues automatically:
./scripts/validate.py --fix
This fixes: file permissions, directory permissions, backup permissions, gitignore. It does NOT auto-fix format issues or encrypt keys — those require manual action.
Step 4: Setup GPG and Encrypt Private Keys
# First-time GPG setup (configures agent cache, tests encrypt/decrypt)
./scripts/setup-gpg.sh
# Optional: --cache-hours 12 (default: 8)
Encrypt high-value keys:
# Encrypt wallet + Farcaster private keys
./scripts/encrypt.py --keys MAIN_WALLET_PRIVATE_KEY,FARCASTER_CUSTODY_PRIVATE_KEY,FARCASTER_SIGNER_PRIVATE_KEY,FARCASTER_LEGACY_CUSTODY_PRIVATE_KEY,FARCASTER_LEGACY_SIGNER_PRIVATE_KEY
What happens:
- Prompts for a GPG passphrase (or reads
OPENCLAW_GPG_PASSPHRASEenv var) - Extracts specified key values from
.env - Stores them encrypted in
~/.openclaw/.env.secrets.gpg(AES256, mode 600) - Replaces
.envvalues withGPG:KEY_NAMEplaceholders - Scripts using
get_credential()or_load_cred()decrypt transparently
Save passphrase to .env for automated decryption:
echo 'OPENCLAW_GPG_PASSPHRASE=your-passphrase-here' >> ~/.openclaw/.env
chmod 600 ~/.openclaw/.env
Verify encryption:
# Check .env has GPG placeholders
grep "GPG:" ~/.openclaw/.env
# List all encrypted keys
./scripts/encrypt.py --list
Step 5: Initialize Rotation Tracking
./scripts/rotation-check.py --init
Auto-classifies all keys by risk:
- Critical (90-day rotation):
*PRIVATE_KEY,*MNEMONIC,*SEED,*WALLET_KEY,*CUSTODY*,*SIGNER* - Standard (180-day rotation):
*API_KEY,*SECRET,*TOKEN,*BEARER,*CONSUMER*,*ACCESS* - Low (365-day rotation): Everything else
Creates ~/.openclaw/.env.meta (mode 600) with creation dates and rotation schedules.
Check rotation status anytime:
./scripts/rotation-check.py
Step 6: Cleanup Old Credential Files
# Dry run first — see what would be deleted
./scripts/cleanup.py
# Actually delete (prompts for 'DELETE' confirmation)
./scripts/cleanup.py --confirm
Also manually remove migrated files not caught by the scanner:
# Example: farcaster-credentials.json was manually migrated
cp ~/.openclaw/farcaster-credentials.json ~/.openclaw/backups/credentials-old-YYYYMMDD/farcaster-credentials.json.bak
chmod 600 ~/.openclaw/backups/credentials-old-YYYYMMDD/farcaster-credentials.json.bak
rm ~/.openclaw/farcaster-credentials.json
Step 7: Update Scripts That Referenced Old Files
Any scripts that loaded from JSON credential files or hardcoded paths need updating.
Pattern — Bash scripts:
# OLD (insecure):
FARCASTER_CREDS="/home/user/.openclaw/farcaster-credentials.json"
fid=$(jq -r '.fid' "$FARCASTER_CREDS")
private_key=$(jq -r '.custodyPrivateKey' "$FARCASTER_CREDS")
# NEW (secure, GPG-aware):
ENV_FILE="$HOME/.openclaw/.env"
_load_cred() {
local key="$1"
local value
value=$(grep "^${key}=" "$ENV_FILE" | head -1 | cut -d= -f2-)
if [[ "$value" == GPG:* ]]; then
local gpg_key="${value#GPG:}"
local passphrase="${OPENCLAW_GPG_PASSPHRASE:-}"
if [ -n "$passphrase" ]; then
value=$(echo "$passphrase" | gpg -d --batch --quiet --passphrase-fd 0 "$HOME/.openclaw/.env.secrets.gpg" | python3 -c "import json,sys; print(json.load(sys.stdin).get('$gpg_key',''))")
else
value=$(gpg -d --batch --quiet "$HOME/.openclaw/.env.secrets.gpg" | python3 -c "import json,sys; print(json.load(sys.stdin).get('$gpg_key',''))")
fi
fi
echo "$value"
}
fid=$(_load_cred "FARCASTER_FID")
private_key=$(_load_cred "FARCASTER_CUSTODY_PRIVATE_KEY")
Pattern — Node.js scripts:
// OLD (insecure):
const creds = JSON.parse(fs.readFileSync('~/.openclaw/farcaster-credentials.json'));
const privateKey = creds.custodyPrivateKey;
// NEW (secure, GPG-aware):
const ENV_PATH = path.join(os.homedir(), '.openclaw/.env');
const SECRETS_PATH = path.join(os.homedir(), '.openclaw/.env.secrets.gpg');
function loadCred(key) {
const content = fs.readFileSync(ENV_PATH, 'utf8');
for (const line of content.split('\n')) {
if (line.startsWith(key + '=')) {
let value = line.slice(key.length + 1).trim();
if (value.startsWith('GPG:')) {
const { execSync } = require('child_process');
const passphrase = process.env.OPENCLAW_GPG_PASSPHRASE || '';
const cmd = passphrase
? `echo "${passphrase}" | gpg -d --batch --quiet --passphrase-fd 0 "${SECRETS_PATH}"`
: `gpg -d --batch --quiet "${SECRETS_PATH}"`;
const secrets = JSON.parse(execSync(cmd, { encoding: 'utf8' }));
return secrets[value.slice(4)] || '';
}
return value;
}
}
return '';
}
const privateKey = loadCred('FARCASTER_CUSTODY_PRIVATE_KEY');
Pattern — Python scripts:
# Use the enforce module (recommended):
import sys
from pathlib import Path
sys.path.insert(0, str(Path.home() / 'openclaw/skills/credential-manager/scripts'))
from enforce import get_credential
private_key = get_credential('FARCASTER_CUSTODY_PRIVATE_KEY') # Auto-decrypts GPG
Step 8: Final Validation
# Run full validation — should show all green
./scripts/validate.py
# Verify encrypted keys
./scripts/encrypt.py --list
# Check rotation status
./scripts/rotation-check.py
# Test a script that uses credentials
bash /path/to/your/script.sh
Expected final state:
~/.openclaw/
├── .env # All credentials (mode 600, private keys = GPG:*)
├── .env.secrets.gpg # GPG-encrypted private keys (mode 600)
├── .env.meta # Rotation tracking metadata (mode 600)
├── .env.example # Template (safe to share)
├── .gitignore # Protects .env, .env.secrets.gpg, .env.meta
└── backups/ # (mode 700)
└── credentials-old-YYYYMMDD/ # (mode 700)
└── *.bak # Backup files (mode 600)
For Skill Developers: Enforce This Standard
Other OpenClaw skills MUST validate credentials are secure before using them:
Python Skills
#!/usr/bin/env python3
import sys
from pathlib import Path
# Add credential-manager scripts to path
sys.path.insert(0, str(Path.home() / '.openclaw/skills/credential-manager/scripts'))
# Enforce secure .env (exits if not compliant)
from enforce import require_secure_env, get_credential
require_secure_env()
# Now safe to load credentials (handles GPG-encrypted keys transparently)
api_key = get_credential('SERVICE_API_KEY')
wallet_key = get_credential('MAIN_WALLET_PRIVATE_KEY') # Auto-decrypts from GPG
Bash Skills
#!/usr/bin/env bash
set -euo pipefail
# Validate .env exists and is secure
if ! python3 ~/.openclaw/skills/credential-manager/scripts/enforce.py; then
exit 1
fi
# Now safe to load
source ~/.openclaw/.env
This creates a fail-fast system: If credentials aren't properly secured, skills refuse to run. Users are forced to fix it.
Loading Credentials
After migration, load from .env:
Python
import os
from pathlib import Path
# Load .env
env_file = Path.home() / '.openclaw' / '.env'
with open(env_file) as f:
for line in f:
if '=' in line and not line.strip().startswith('#'):
key, val = line.strip().split('=', 1)
os.environ[key] = val
# Use credentials
api_key = os.getenv('SERVICE_API_KEY')
Bash
# Load .env
set -a
source ~/.openclaw/.env
set +a
# Use credentials
echo "$SERVICE_API_KEY"
Using Existing Loaders
If you migrated using OpenClaw scripts:
from load_credentials import get_credentials
creds = get_credentials('x')
Adding New Credentials
Edit ~/.openclaw/.env:
# Add new service
NEW_SERVICE_API_KEY=your_key_here
NEW_SERVICE_SECRET=your_secret_here
Update template too:
# Edit .env.example
NEW_SERVICE_API_KEY=your_key_here
NEW_SERVICE_SECRET=your_secret_here
If the new credential is high-value (private key, wallet key):
# Add to .env first, then encrypt
./scripts/encrypt.py --keys NEW_SERVICE_PRIVATE_KEY
Security Best Practices
See references/security.md for detailed security guidelines.
Quick checklist:
- ✅
.envhas 600 permissions - ✅
.envis git-ignored - ✅ Backup files have 600 permissions
- ✅ Backup directories have 700 permissions
- ✅ No credentials in code or logs (use
--deepscan to verify) - ✅ Private keys encrypted with GPG
- ✅ Rotation schedule established and tracked
- ✅ Symlinked .env files point to the main .env only
- ✅ No credentials in shell history (use
source, notexport KEY=val)
Rollback
If something goes wrong:
# Find your backup
ls -la ~/.openclaw/backups/
# Restore specific file
cp ~/.openclaw/backups/credentials-old-YYYYMMDD/x-credentials.json.bak \
~/.config/x/credentials.json
# Decrypt GPG secrets back to plaintext
./scripts/encrypt.py --decrypt --keys MAIN_WALLET_PRIVATE_KEY
Notes
- Non-destructive by default: Original files backed up before removal
- Idempotent: Safe to run multiple times
- Extensible: Add custom credential patterns in scripts
- Secure: Never logs full credentials, only metadata
- GPG-aware: Transparently handles encrypted and plaintext credentials
- Backup-hardened: All backups secured with proper permissions
- Symlink-aware: Detects and validates symlinked credential files
