Personal finance aggregators are tools that help users manage and track their financial accounts, including bank accounts, credit cards, investments, and loans.

An aggregator is a software tool that takes data from multiple sources and provides centralized access to it. When it comes to personal finance aggregators, the consumer has many choices.  Although the author i Mint was the original. Although it's been owned by Intuit since 2009 (which also owns QuickBooks and TurboTax), there was nothing like it when it was first created.  For the first time, you could automatically pull your personal financial data, from all the financial institutions that you do business with, into one place at the click of a button.  Checking and savings accounts, credit cards, investment accounts, a complete financial picture:  assets and liabilities, including personal and student loans, credit cards, home mortgage and home equity.  You could see your accurate, real-time net worth just by opening the app.

The average person has 15 different financial accounts: checking and savings, credit cards, student loans, investment accounts, and more. To keep your financial future on track, the simplicity of being able to see everything in one place has obvious benefits.  However, there are unique challenges to this space that explain why Mint was the undisputed leader for so long.

When comparing personal finance aggregators, there are many key features to consider:

Each personal finance aggregator has its own set of features and capabilities, and the right choice for you will depend on your specific financial needs and goals. Mint and Personal Capital are both great options for those who want a comprehensive view of their finances, while YNAB and Monarch are more focused on budgeting.

Mint is one of the most popular personal finance aggregators, offering a wide range of features such as budgeting tools, investment tracking, and bill reminders. Personal Capital is similar to Mint, but also includes retirement planning and credit score monitoring. YNAB (You Need a Budget) is focused on budgeting, unsurprisingly, and is a paid service. Monarch Money also requires a paid subscription, and has on its team some of the original Mint creators from years ago.

Is this safe?

An aggregator like Monarch has to integrate with many different financial institutions.  Some of them are technically advanced, and provide systems for faciliting this integration like APIs.  Getting data from less enlightened instutions requires more radical solutions like "scraping", or extracting data from the institution's own web interface.  Regardless, the aggregator must keep authentication information that allows access to your data across different accounts and different organizations.  The first question people ask when considering Mint is often, "Is it safe for Mint to have all my financial passwords?"

There are three ways the risk is mitigated, and in my opinion, acceptable.

First, some financial institutions offer a way to use read-only authentication credentials.  This is sometimes called a "token", and is separate from the main password that gives full access to your accounts.  By providing Mint (or any other aggregator) a read-only login token rather than your primary credentials, you can be assured that nothing bad can happen if the credentials are stolen.  Institutions like Capital One 360 offer this kind of access for Mint to use.

Secondly, Mint is now owned by Intuit, which is the software company that creates and manages QuickBooks, TurboTax, and other financial products.  Identity theft is a serious issue in the 21st century, and if you think a hacker having access to your bank account is worrisome, imagine what the hacker could do with your tax returns and social security information.  The point here is that Intuit has a history of managing mission-critical financial software products and systems, and if TurboTax has been safe to use for over a decade, you can trust that Intuit will also be as vigilant in keeping Mint safe and secure.  Of course, nothing is guaranteed in this world, but you can be sure that if a security breach of Mint does occur you would hear about it and so far their track record has been spotless.

Finally, your accounts are protected in other ways.  Both VISA and MasterCard have a zero-liability fraud policy, which means as long as you report fraudulent activity without delay once it's discovered, you will not be held liable for fraudulent charges.  This protects not only your credit cards, but also your debit cards and other accounts where the VISA or MasterCard logos are displayed.  Also, bank accounts are strictly regulated by law, and your liability for fraudulent activity there is also severely limited if you report it promptly.  It would be big news if someone lost a lot of money, or even any money, as a result of using an aggregator like Mint.  Although they are a relatively new concept, they have been around for a few years now and you can be sure the negative publicity would be hard to miss if a breach did occur.
