### Options
| Option | Description |
|--------|-------------|
| `--name` | Entry name (required) |
| `--type` | Entry type (password/token/api_key/secret) |
| `--username` | Username (optional) |
| `--password` | Password/value (auto-generate if not provided) |

| `--new` | New master password (for change-password) |
## Advanced Usage
### Environment Variable Support
For automation and CI/CD, you can use the `PASSWORD_MANAGER_MASTER_PASSWORD` environment variable:
```bash
# Set environment variable
export PASSWORD_MANAGER_MASTER_PASSWORD="your-master-password"
# Now you don't need to enter password interactively
password-manager list
password-manager add --name "github" --type "token" --password "ghp_xxx"
password-manager change-password --old "old-pass" --new "new-pass"
```
**Security Note**: Be cautious when using environment variables in shared environments, as they may be visible in process lists.
### Cache Auto-Rebuild
When the cache file is missing or expired, the password manager will automatically attempt to rebuild it:
1. **Cache Missing**: If `.cache/key.enc` doesn't exist, the system will try to rebuild from the provided password
2. **Environment Variable**: If `PASSWORD_MANAGER_MASTER_PASSWORD` is set, it will be used for cache rebuild
3. **Interactive Prompt**: If no environment variable, you'll be prompted to enter the password
```bash
# First run after cache expiration
$ password-manager list
๐ Cache missing, attempting to rebuild...
โ
Cache rebuilt successfully
# Subsequent runs (within 48 hours)
$ password-manager list
โ
Using cached key (expires in 47h 59m)
```
## Configuration
`config.json` includes reasonable defaults and can be used directly. Edit for customization:
```json
{
"cacheTimeout": 172800, // Master password cache timeout (seconds, default: 48 hours)
"maxHistoryVersions": 3, // Number of historical versions to retain
"auditLogLevel": "all", // all/sensitive/none
"autoDetect": {
"enabled": true, // Enable sensitive information detection
"sensitivityThreshold": "medium",
"askBeforeSave": true
},
"requireConfirm": {
"delete": true,
"deleteAll": true,
"export": true,
"backup": true,
"restore": true
},
"generator": {
"defaultLength": 32,
"includeUppercase": true,
"includeNumbers": true,
"includeSymbols": true
}
}
```
**Tip**: If configuration is modified incorrectly, refer to `config.example.json` to restore defaults.
## Security Documentation
### Implemented Security Measures
1. **AES-256-GCM Encryption** - Military-grade encryption protection
2. **PBKDF2 Key Derivation** - 100,000 iterations
3. **Dual Encryption** - Vault and cache encrypted separately
4. **Unbiased Random Numbers** - Uses `crypto.randomInt()`
5. **Input Validation** - Sanitization at all entry points
6. **Sensitive Operation Confirmation** - Re-enter password for deletion
7. **Memory Cleanup** - `secureWipe()` removes sensitive data
8. **Audit Logs** - Records operations without content
### Security Recommendations
1. **Master Password**: Cannot be recovered if lost, store securely
2. **Regular Backups**: Backup to external storage weekly
3. **Strong Master Password**: Use 16+ character random password or passphrase
4. **Lock Promptly**: Manually lock when not in use for extended periods
5. **Protect Configuration**: Do not upload config.json to public repositories
6. **Audit Logs**: Regularly check `.logs/detection.jsonl`
### Remaining Risks
| Risk | Likelihood | Impact | Mitigation |
|------|------------|--------|------------|
| Cache file depends on filesystem permissions | Low | Medium | Encrypted |
| Memory keys may be dumped | Low | High | secureWipe added |
| Master password loss cannot be recovered | - | High | User education |

## Frequently Asked Questions (FAQ)
**Q: What if I forget my password?**
A: The master password cannot be recovered if lost. Please backup regularly and store your master password securely.
**Q: How do I change my master password?**
A: The current version does not support changing the master password. You need to reinitialize and migrate data.
**Q: Where is the vault file?**
A: `~/.openclaw/workspace/skills/password-manager/data/vault.enc`
**Q: How do I view operation logs?**
A: Log files are in `.logs/detection.jsonl`, recording detection events without specific content.
**Q: How do I disable sensitive information detection?**
A: Edit `config.json` and set `autoDetect.enabled: false`
**Q: Is the cache file secure?**
A: The cache file is encrypted with AES-256-GCM and relies on filesystem permissions for protection.
**Q: What entry types are supported?**
A: Supports four types: `password`, `token`, `api_key`, `secret`.
