Online services in QuickBooks are very secure.
Online banking is protected with a password that is issued only to you. To download electronic statements, QuickBooks uses a secure Internet connection and high-level encryption.
Online vendor payment is protected in the same way. It requires a password and sends payment instructions using a secure Internet connection and high-level encryption. After your financial institution receives your instructions, the electronic payments are handled by protected processing systems.
Also, if several people use QuickBooks, you can restrict others from using online services.
