never heard of wave. Mint is owned by Intuit, who are very reputable. I can't say I have ever heard of any 'hacking' stories dealing with Mint yet (knock on wood). I use Mint and it's great...quick way to get a snap shot of your financial life with the ability to dive into the details if you so wish. Setting it up can be a pain in the ass sometimes as you'll need your security question answers from the financial instituions you are using, i believe. Also, not every financial institution is on Mint. But i have PNC, Chase, Vanguard, and Mercer on Mint. Only thing i couldnt add was a small account at my local credit union, which was not a big deal. Mint is also smart enough to ask you you if a certain asset is tied to a certain liability (i.e. "is this mortgage tied to this house?") It's free..so may as well give it a shot.
