E-Commerce sellers should guard their seller accounts against hacking. Someone gaining access to your PayPal can take all your money away. If your Amazon Seller Account is hacked, one can change the bank account and redirect Amazon's seller payment to somewhere else.

Now, if someone have access to your voice mail, they can change your voice greetings to the required 4 digit code key press sound after a long delay, thus gaining access to your PayPal.
