I use Wesabe to manage my money (I'm not involved in the company and I don't know them). They have a client application for Windows and OS X that downloads your data from your bank and sends it to them, so your bank credentials never leave your computer. For Linux users like me, or anyone who doesn't want to install the client, you can download the Quicken/Money files from your bank and upload it to Wesabe directly. It's nifty stuff, and built with security in mind. I think they came out with a Firefox extension to replace the desktop client recently, and that works on Linux as well, but I haven't used it yet. Which reminds me, I should probably go sync my data again. Edit: Now I've used the Firefox extension, and it works like a charm. Apparently some banks allow you to programmatically access your data somehow, and the extension is capable of automatically getting the data that way, but my bank, Wells Fargo, doesn't. In this case, the extension tells you to download your data manually while it records all the actions you take so it can play them back automatically. Neat. My only gripe with the extension is that it wants you to add a button to your toolbar instead of just using an entry in the Tools menu. I went ahead and added it, set up my accounts to update automatically, then removed the button.
