I use Quicken to manage my accounts. I do not worry about transmitting transactions even over open public networks. Quicken encrypts the data before it goes on the network. They claim it is bank level encryption. Have been doing this for cash flow management since 2003 when the only access was to carry the computer to the cg office and plug into the modem line (I watched people pack a desktop machine and monitor to the office!). I have not been hacked YET! When I access my bank directly I make sure to verify that the https: shows in the address bar. 128 bit encryption will take just a bit of computer power and a year or two to break. No worries!
