Dear valued customer,
ez1099 software is a desktop version so it is not available online to be hacked by others. We believe the current Windows security is sufficient for our clients.
You can lock your computer automatically when you are away from your desk
If you share the same computer with other people, you can choose "Just me" option when you install ez1099. So others can not see it when they log in with a different user ID.
Please let us know if you have further questions.
