I tried it out, seems to be okay. I might just opt out since bank account transactions never show pending stuff. But I may leave things like Gamefly, BlockBuster, and bills on there.
For some reason I didn't hesitate, I just figure that there a lot of other services like this out there, and if it wasn't protected, they wouldn't be around. But there's always that fear. I guess I wish there was a good offline app for PC desktop for this kind of thing. I don't think 1Password is for PC.
The service works well enough on the website. Sometimes refreshing the data on the iPhone takes a while. I like the feed section, showing changes to all accounts in a list. Or how I can check how many minutes and other usage with my ATT account.
They seem to respond quickly for adding in sites they don't have. Like they didn't have GameFly, so I requested it, and only a week later they e-mail me that they now have it in their system so I can instantly check what has shipped and what's in my queue with availability.
On the website, clicking shopping will show all those accounts at once, ebay, blockbuster, gamefly, etc. Utilities page shows Comcast, PG&E, ATT phone/dsl and ATT Cell. A few have bill pay options, like PG&E, which they will have more available to other accounts in the future.
On the iPhone, it's mostly read only, no auto log-in to other sites, etc.
If you signed up and now having second thoughs, you can e-mail the support to delete the entire account.
