Connecting your bank, brokerage, and retirement accounts is the first step to getting value from Truthifi. Most people pause here, not because it's complicated, but because handing a third-party app access to your finances feels like a big ask. That hesitation is worth taking seriously. This article explains exactly what happens when you connect, who handles your credentials, how financial data aggregation works, and why the process is designed to keep you in control at every step.

What is Plaid, and why does Truthifi use it?

If you've used a personal finance app in the last few years, you've almost certainly used Plaid without knowing it. Plaid is a financial data aggregation company: it specializes in creating secure, standardized connections between consumer bank accounts and third-party apps. It powers connections for thousands of products including Venmo, Robinhood, Coinbase, and Betterment. In the world of account aggregation, Plaid is the most widely recognized name, but it's one of several providers operating in this space.

Truthifi also uses Yodlee and ByAllAccounts, two other established financial data aggregation providers. Yodlee has been in the financial data business since 1999 and connects to a large range of institutional and retail accounts. ByAllAccounts specializes in wealth management and investment account aggregation, which makes it particularly useful for connecting brokerage and retirement accounts that some other providers don't cover as well.

So when you ask "what is Plaid banking" or "what is a financial data aggregator," the short answer is: it's a regulated intermediary that sits between your bank and apps like Truthifi. It authenticates you, retrieves your data, and passes it along in a standardized format, without the app ever needing to know your password.

Is Plaid safe to use? What about Yodlee and ByAllAccounts?

This is one of the most common questions people have before connecting their accounts, and it's a fair one. The short answer is yes, but here's why.

Plaid, Yodlee, and ByAllAccounts are all regulated financial data companies. They use bank-level encryption, they do not store your full login credentials after the initial authentication, and they are subject to oversight from financial regulators. Plaid in particular has undergone significant regulatory scrutiny and has published detailed documentation on its security practices at plaid.com/safety.

More importantly: your credentials never reach Truthifi at all. When you log in through the connection window, you are logging in directly with the data provider, not with us. What Truthifi receives is a read-only access token: a secure key that lets us pull your account data without knowing your password. If you disconnect your account, that token is revoked and Truthifi can no longer access your data. It's a system specifically designed so that "is Plaid safe to use" has a clean, verifiable answer: yes, because the design prevents misuse even if something were to go wrong on the app side.

What does "read-only" mean in practice?

Read-only means exactly what it sounds like. The connection Truthifi holds can pull data: balances, holdings, transaction history, net worth. It cannot push anything back. It cannot initiate a transfer, place a trade, make a payment, or change any setting inside your account. There is no write access involved at any point.

This matters because it sets a hard technical limit on what is possible, not just what Truthifi promises to do, but what the connection is actually capable of. A read-only token cannot move money by design. It's the same principle behind view-only access in other software: even if someone obtained your token, they couldn't do anything actionable with it beyond seeing your balances.

Truthifi uses this read-only data to power your dashboard, run automated financial diagnostics across 130+ wellness checks, and (via Truthifi Connect) pipe clean, normalized data into AI tools like Claude and ChatGPT so you can ask questions about your own finances in plain language. None of that requires write access, and Truthifi does not have it.

Which institutions does Truthifi support?

Truthifi supports over 18,000 financial institutions across the US, including major retail banks, brokerages, credit unions, retirement plan providers, credit card issuers, and mortgage lenders. Most large institutions, Chase, Bank of America, Wells Fargo, Fidelity, Vanguard, Schwab, Robinhood, and hundreds more, are already in our system.

Coverage varies by institution and by data provider. In some cases Truthifi may connect to a given bank via Plaid, while a brokerage connects via ByAllAccounts and a retirement account via Yodlee. This is handled automatically based on which provider offers the strongest connection for each institution. You won't need to choose: just search for your institution and Truthifi handles the rest.

If your institution doesn't appear in the search results, try alternate names or abbreviations. If it's still not there, contact our support team. We add institutions regularly and can flag missing ones for prioritization.

How to disconnect an account

You can remove any connected account at any time from your Truthifi settings. Go to Settings > Accounts, select the institution you want to disconnect, and click Disconnect. There are no support tickets to file, no waiting periods, and no phone calls required. The connection is revoked immediately, and Truthifi will stop syncing data from that account.

If you want to remove your data from Truthifi entirely, you can request a full data deletion by contacting our support team. We'll process that request and confirm when it's complete.
