Banks rightly encourage their internet banking customers to be careful to prevent fraud and to not allow their passwords to fall into the hands of fraudsters. There is a clear distinction between you allowing fraudulent misuse of passwords, and using them in a secure environment to allow you to better manage and understand your own money. The transactions are your transactions. The balances are your balances. The data managed by the bank on your behalf is your data. Money Dashboard provides a service designed to empower you to get the most out of your data, by helping you to see the true view of your financial life.
Some banks explicitly acknowledge the benefit of aggregation services, such as ours, in their Terms and Conditions and therefore directly permit aggregation. Others do not, however, this does not necessarily mean they do not want you to aggregate your accounts. Some banks, perhaps understandably, will be reluctant to endorse any external organisation unless they have undertaken rigorous checks on them. Given the international nature of aggregation, this is a near impossible task for banks.
For the most part, advice from a bank is therefore based on a cautious approach. Ultimately, it is your decision as to whether you use our service; please read this post for more information on how we keep your details secure.
