I wish banks would offer something like OAuth - a service-specific, revokable credential with access only to the stuff it needs. I'd be a lot more inclined to use a product like Mint, for example, if I could grant it ONLY read access to my transactions and I knew I could revoke that access at any time without having to change my primary credentials or disrupt any other services/apps I have connected.
