Hello,First, No, Quicken is NOT web-based. They offer a web-based companion to their desktop program but its basic at best right now. (hopefully getting better soon).As far as you and your wife accessing it, thats another issue. You can install the program on your computer and hers with no issue. You would want to be accessing only 1 file though. (otherwise it gets messy trading backups back and forth). Also, you would NOT want to both be accessing the data file at the same time. Quicken is NOT designed to have multiple people logged in to the same file at the same time.What you could do is 1 of 2 things.1. You use the desktop program for entering and updating info as needed. Your wife can log into the web-based app to view data. The data on the web will be updated as you edit the desktop file and SYNC it to the cloud.2. If you have another computer on your home network that is always on (like a media center PC) you can install Quicken and the data file there and remote into that computer anytime you want to view Quicken. Just make sure you and your wife are not trying to log into it at the same time.
