---

### updatePwd

export const updatePwd = (pwd) => {
  return update(pwdUrl, pwd);

---

### reset

```typescript
export const reset = (user) => {
  return update(root + '/' + user.userId, {});
};
```

- **URL**: `user/{userId}` with empty body
- **Uses**: `update` from base (PUT)
- **Purpose**: Admin password reset

---

## Usage Example

```typescript
import { user } from 'plugs/api';

// List users
const users = await user.list({ status: 1 });

// Add user
await user.add({ username: 'john', email: 'john@example.com' });

// Update user
await user.set({ userId: 123, username: 'johnny' });

// Delete user
await user.del({ userId: 123 });

// Change password
await user.updatePwd({ oldPwd: '...', newPwd: '...' });

// Reset user password (admin)
await user.reset({ userId: 123 });
```

---

## Anti-Patterns

1. **`del` requires full object** - Must pass `{ userId: ... }` not just the ID
2. **`reset` uses empty object** - Unclear why empty `{}` is sent as PUT body
