Security Checklist for AI Financial Applications

An AI financial application may combine sensitive identity information, account data, transactions, investment holdings, and personal questions in one place. Before connecting anything, verify what the application collects, how it connects, what it can do, who receives the data, and how you can revoke access.

Security is not proved by a lock icon or a broad claim of “bank-level” protection. A useful review examines permissions, authentication, data handling, vendors, retention, support, and the limits of the AI itself.

The 12-point AI financial app security checklist

1. Verify the company behind the application

Confirm the legal company name, website, support channels, privacy policy, and terms of service. Search for credible reporting, regulatory actions, security incidents, and unresolved complaints. A polished interface does not establish legitimacy.

2. Identify every type of data the app collects

Separate information you enter manually from information imported through connected accounts. Look for identity data, account balances, transactions, holdings, documents, chat messages, device data, and behavioral analytics.

Ask whether the app needs each category to deliver the feature you want. Avoid uploading Social Security numbers, account numbers, tax documents, or other sensitive records into a general-purpose chatbot unless the service clearly requires them and you have evaluated its controls.

3. Understand how accounts are connected

FINRA explains that financial aggregation can use APIs or screen scraping. APIs can let consumers authorize access without giving the third party their security credentials and may limit the scope of access. Screen scraping can require credentials and may create additional risks.

Check whether the application uses an established connection provider, redirects authentication to the financial institution or provider, and explains what happens when a connection is revoked.

4. Confirm whether access is read-only

A monitoring application needs different permissions from a payments application. Determine whether the service can only read balances and transactions or can also initiate transfers, trades, or payments. Treat any money-movement permission as a materially higher-risk decision.

5. Check whether credentials are stored

The application should explain whether it ever receives or stores your bank username and password. Prefer connection flows that keep authentication with the institution or a clearly identified connection provider. Never send a password, PIN, or verification code through an AI chat.

6. Require strong account authentication

The FTC recommends two-factor authentication for accounts containing personal and financial information. Authenticator apps and security keys generally provide stronger protection than text or email codes when they are available.

Use a unique password stored in a reputable password manager. Protect the email account used for recovery with equally strong authentication.

7. Look for encryption and secure transmission

The provider should describe whether data is encrypted during transmission and while stored. Encryption matters, but it is only one control. Access management, software updates, vendor oversight, logging, incident response, and deletion practices also affect risk.

8. Review third-party access

Financial applications may rely on account aggregators, cloud providers, analytics services, AI model providers, customer-support tools, and identity-verification vendors. The privacy policy should explain the categories of recipients and the purposes for sharing.

Ask whether access is limited to the data needed for the feature, whether vendors may use the data for their own purposes, and how access is monitored.

9. Ask how AI inputs and outputs are used

Find out whether prompts, uploaded documents, connected financial data, and generated answers are used to train or improve models. Determine whether humans may review conversations, how sensitive information is filtered, and how long chat history is retained.

Also assess the AI’s decision authority. An assistant that summarizes information presents a different risk from a system that can execute transactions or automatically change a portfolio.

10. Confirm retention, deletion, and export controls

You should be able to understand how long data remains after you disconnect an account or close your profile. Check whether deletion covers derived data, uploaded documents, conversations, backups, and vendor copies, subject to legitimate legal retention obligations.

The CFPB advises consumers to understand how financial data is used, how long access lasts, and how to stop access when they no longer use a service.

11. Review incident and support procedures

Look for a clear way to report a security issue, unauthorized access, or inaccurate data. Understand how the company says it will notify users after an incident and what steps are available to revoke connections or secure the account.

12. Test revocation before you need it

Know how to disconnect a bank or brokerage, delete an uploaded file, close the application account, and revoke access through the financial institution. Removing an app from your phone may not terminate its account access.

Security controls to turn on immediately

• Enable the strongest multi-factor authentication method offered.
• Use a unique password and do not reuse your bank password.
• Turn on alerts for new logins, password changes, connected applications, and financial transactions.
• Keep your phone, browser, operating system, and financial applications updated.
• Review connected applications from your bank and brokerage settings periodically.
• Contact a company through a verified website or statement, not through a link in an unexpected message.

The FTC warns against clicking links or downloading attachments in unexpected messages. It recommends contacting the company through a phone number, email address, or website you already know is genuine.

Red flags that should stop the connection

• The app asks you to send bank credentials, PINs, or verification codes through chat, email, or text.
• It cannot explain whether access is read-only or permits transactions.
• Its privacy policy does not identify the company or describe data use.
• It asks for substantially more data than the requested feature needs.
• It pressures you to move money to “protect” an account.
• It promises guaranteed investment, tax, or financial outcomes.
• There is no clear way to revoke access, delete data, or contact support.

How CFO Silvia describes its security controls

CFO Silvia’s current website states that its access is read-only and that Silvia cannot move money. It also states that bank logins remain with Plaid, crypto connections use OAuth, credentials are not stored by CFO Silvia, and data is encrypted at rest and in transit.

The site further states that user data is not sold, internal access is logged, data is deleted on request when an account is closed, and the company is SOC 2 Type II certified. These are first-party statements. Users should still review the current privacy policy, terms, available authentication controls, and connection permissions before linking accounts.

Frequently asked questions

Is read-only access completely risk-free?

No. Read-only access reduces the risk of unauthorized money movement through the application, but exposed financial data could still create privacy, fraud, or identity risks. Authentication, encryption, vendor controls, monitoring, and revocation remain important.

Is OAuth safer than giving an app my password?

OAuth and API-based connections can allow scoped authorization without giving the application your password. The exact security depends on the implementation, permissions, provider, and your own account protections.

Should I connect every account immediately?

Start with the minimum access needed to evaluate the service. Review the results and controls before expanding the connection to more sensitive or complex accounts.

Can an AI finance app replace professional advice?

No security control makes an AI output automatically correct or suitable for your circumstances. Verify consequential financial decisions and consult a qualified financial, tax, accounting, or legal professional when personalized judgment is required.
