ByAllAccounts is one of Truthifi's own connection partners and one of the most established names in investment-data aggregation. It's Morningstar's investment-focused data-aggregation service, built for holdings, positions and cost basis rather than everyday checking data. It's permission-based and read-only for investment data, backed by Morningstar's information-security program and used by thousands of advisory firms. Below: how it works, how it protects your data, and how you stay in control.

Where we stand: Truthifi connects through ByAllAccounts, alongside Plaid and Yodlee, so we have a business interest in it being trustworthy. That's why the key claims below point to Morningstar's own materials.

What is ByAllAccounts?

ByAllAccounts is a financial data aggregator that specializes in investment accounts. It connects advisors, wealth platforms and their clients to brokerage, retirement and custodial accounts so the data can be read with permission. Where Plaid, Yodlee and Finicity grew up around consumer banking, ByAllAccounts is built around portfolios: holdings, positions and cost basis. Data can be shared two ways: investor-permissioned aggregation of your held-away accounts through ByAllAccounts Connect, or advisor-permissioned aggregation through AccountView. Morningstar acquired ByAllAccounts in 2014 and, according to WealthTech Strategy (2026), says it continues to operate as a business within Morningstar. Get started with Truthifi

How does ByAllAccounts protect your data? (is ByAllAccounts secure?)

ByAllAccounts reads your investment data on a permissioned, read-only basis and runs on an enterprise security program. Morningstar says it maintains a comprehensive information-security program with physical, technical and administrative safeguards. Because ByAllAccounts also serves advisors and wealth platforms, in that context the connection is designed to deliver your portfolio data to the advisor or platform the investor authorizes.

• Read-only investment data: the connection reads balances, holdings, positions and cost basis; it isn't a payments rail and doesn't move money.

• Permission-based: data flows only to the advisor or platform you've authorized, through investor-permissioned (ByAllAccounts Connect) or advisor-permissioned (AccountView) access.

• Cleaned at the source: Morningstar parses, normalizes and enriches the data so holdings line up accurately across accounts.

Where Truthifi fits: Truthifi's access to your accounts is read-only. Your AI assistant can look, but it can't move money, place trades or change anything in those accounts. You sign in to your bank or broker through Truthifi's connection partner (Plaid, Yodlee or ByAllAccounts), not through Truthifi, and Truthifi doesn't see or store your login.

Does ByAllAccounts sell my data?

No. ByAllAccounts is a business-to-business investment-data service: it aggregates your portfolio data and delivers it to the advisor or wealth platform you've authorized, not to outside buyers. You and your advisor control who sees the data. It exists to give advisors and wealth platforms an accurate, permissioned view of your investments.

As with any connection, it's worth reading the privacy policy of the advisor platform or app you're linking through alongside Morningstar's. Truthifi, for its part, doesn't sell your personal information either.

How do I see and remove ByAllAccounts connections? (revoke / delete)

Because ByAllAccounts connects you through an advisor or a wealth platform, start where you authorized it: the advisor platform or app you linked, or your custodian's connected-access settings. Revoking stops future access. To remove data already collected, ask the platform and Morningstar through its privacy channel.

The aggregator handles the secure connection. Once you link, Truthifi brings your accounts into one view and checks them for fees, concentration and other issues. Run a free Truthifi checkup on your own accounts → (limits apply).

1. Start where you authorized it. Revoke through the advisor platform or app where you linked your accounts, or your custodian's connected-access settings.

2. Know revoking vs deleting. Revoking stops future access only.

3. Request deletion. To remove data already collected, ask the platform and Morningstar through its privacy channel.

What Truthifi adds on top of ByAllAccounts

ByAllAccounts moves your investment data; Truthifi is the layer on top. Connect once through ByAllAccounts, Plaid or Yodlee, and Truthifi standardizes what each institution sends, labeling reinvested dividends correctly and matching the same security across accounts, so you and your AI assistant work from consistent numbers. Here's what that looks like, side by side with an aggregator alone:

ByAllAccounts is one of three networks behind Truthifi; together with Plaid and Yodlee, it reaches 18,000+ financial institutions, with ByAllAccounts especially strong for investment and custodial accounts. Check your institution's status at truthifi.com/connections before you link it.

Ask your own AI assistant about your accounts

Every current consumer plan, free ones included, comes with Truthifi's MCP server. MCP (Model Context Protocol) is an open standard that lets AI assistants connect to outside tools and data. Connect an assistant such as Claude from its own connector menu, then sign in to Truthifi and choose Authorize. For most assistants there's no API key to enter, and you don't need spreadsheets or code. The built-in Truthifi AI agent is also included with Monitoring and Monitoring Plus+. Connect Truthifi to your AI agent.

Then ask: "Which of my accounts costs me the most in fees?" You see the fees on each account, by type (in your own AI assistant this needs Connect Max, Monitoring or Monitoring Plus+). Deeper questions, such as your returns against a benchmark, depend on your plan. Truthifi is not an investment adviser and doesn't give investment, tax or legal advice.

One picture for investors, advisors and firms

The same cleaned picture shows how your money splits by asset class, sector, industry and country, and Truthifi checks it for fees, concentration and other issues. On paid plans and Connect Explore, Truthifi refreshes your data automatically once a day, when the connection to your bank or broker is working.

As an investor, you get fees, performance and your Truthifi Score together in one place, and if you work with an advisor or a firm, you can share the accounts you choose with them. Whatever you've chosen to share is visible to your advisor, and you can stop sharing whenever you like. See how Truthifi keeps your accounts secure

Truthifi for financial advisors

Advisors and firms can sponsor their clients. A sponsored client's Truthifi plan is free, paid for by the advisor or firm, and the client decides what to share and can turn sharing off at any time, so you're both working from the same numbers.
