My understanding is that they use http://www.yodlee.com for getting information from your accounts. That's pretty much what everybody does.

I turned it off and deleted my data because the bank or brokerage would change something and break the automatic downloads and things would get out of date.

I believe banks and brokerages should have two levels of access: one where you can move money and one where you can look but not touch. I'd be much happier using the second type of password with Mint, with the bank's own apps, etc. I'm not thrilled at all about the idea of losing my phone and having someone get "write" access to my bank account.

My bank, Capital One 360, has something like this. You can give a read-only access token to an external service and change/disable it at will.

Bank of America has it. They call it Account Management, but AFAIK they charge for using it at least if you're a business account.

I believe Mint does not use Yodlee, while most other sites that offer similar functionality do.

Totally agree. You could even limit it by whichever app you want to give access to.
