Are there any risks from using mint.com?
Some banks allow mint.com read-only access via a separate "access code" that a customer can create.  This would still allow an attacker to find out how much money you have and transaction details, and may have knowledge of some other information (your account number perhaps, your address, etc). The problem with even this read-only access is that many banks also allow users at other banks to set up a direct debit authorization which allows withdrawals.  And to set the direct debit link up, the main hurdle is to be able to correctly identify the dates and amounts of two small test deposit transactions, which could be done with just read-only access. Most banks only support a single full access password per account, and there you have a bigger potential risk of actual fraudulent activity. But if you discover such activity and report it in a timely manner, you should be refunded. Make sure to check your account frequently. Also make sure to change your passwords once in a while.
