You should never give a financial advisor your login credentials, passwords, Social Security number over email, or details about illegal activity you’re involved in. But beyond those obvious boundaries, there are subtler things worth keeping to yourself, at least until you understand the relationship and how your information will be used. Knowing where to draw the line protects your security, your negotiating position, and your privacy.
Login Credentials and Passwords
No legitimate financial advisor will ever ask for your online banking passwords, brokerage account login credentials, or email passwords. If someone managing your money asks for this information, treat it as a serious red flag. FINRA has noted that account intrusions are generally accomplished through the theft of login credentials, and phishing scams that impersonate financial professionals are a common attack vector.
Your advisor may need read-only access to view your accounts, and many financial planning platforms offer secure account-linking tools for exactly this purpose. That is very different from handing over the username and password you use to log in. If your advisor asks you to share credentials directly, through email or otherwise, decline and ask about secure alternatives. A reputable advisor will already have them in place.
Sensitive Identifiers Over Unsecured Channels
At some point during onboarding, your advisor will need identifying information like your Social Security number, date of birth, and bank account details. That’s normal. What matters is how they collect it. You should never send this information through regular email, text message, or any unencrypted channel.
Under federal privacy rules (Regulation S-P), financial institutions are required to maintain written policies designed to protect the security and confidentiality of customer information and guard against unauthorized access. Ask your advisor how they handle sensitive data before you hand it over. A well-run advisory firm will use encrypted portals, secure document-sharing platforms, or in-person collection. If the process feels informal or improvised, that’s a warning sign about how your data will be stored going forward.
Details About Illegal Income or Activity
Financial advisors are not your attorneys, and conversations with them are not protected by any legal privilege. If you share information about unreported income, money laundering, tax evasion, or other illegal activity, your advisor may be legally required to report it.
Under the Bank Secrecy Act, many financial institutions already file Suspicious Activity Reports (SARs) with the Financial Crimes Enforcement Network (FinCEN) when they spot signs of fraud, money laundering, or other illicit activity. FinCEN has proposed expanding these requirements to cover registered investment advisers as well, which would obligate them to implement anti-money laundering programs and share information with law enforcement agencies. Even without a formal mandate, most advisors working through broker-dealers or custodians already operate under firms that file SARs as a matter of course.
The practical takeaway: don’t volunteer information about anything that could be construed as illegal financial activity. Your advisor is not a confidential sounding board for those matters.
Your Maximum Budget Before Negotiating Fees
When you first meet with a financial advisor, you’ll naturally discuss your finances. But there’s a difference between sharing what’s necessary for financial planning and revealing your entire hand before you’ve agreed on a fee structure.
If you tell an advisor exactly how much you’re willing to pay before understanding what services you’re getting, you lose leverage. As one advisor quoted by NerdWallet put it, most people are afraid to negotiate fees because they don’t actually understand what they’re paying for, and when you don’t understand the value, you either overpay quietly or feel uncomfortable questioning it. The worst time to negotiate is after you’ve already committed to a service, because at that point the costs are typically built in.
Before your first meeting, research common fee structures. Advisors typically charge a percentage of assets under management (often around 1%), a flat annual fee, an hourly rate, or some combination. Come prepared to ask what specific services are included and how costs scale as your portfolio grows. Rather than leading with “Can you lower your fee?”, which frames the conversation as a transaction, focus on understanding the value proposition first. Then negotiate from an informed position.
Exaggerated or Dishonest Financial Information
This one cuts the other direction. While there are things you shouldn’t share, there are also things you shouldn’t fabricate. Inflating your income, downplaying your debt, or hiding accounts from your advisor undermines the entire point of the relationship. Your advisor builds a plan based on the numbers you provide. If those numbers are wrong, the plan will be wrong.
A common version of this is omitting debts you’re embarrassed about, like credit card balances, personal loans from family, or past-due accounts. Your advisor isn’t there to judge your spending. They need accurate information to recommend appropriate investment strategies, insurance coverage, and savings targets. Hiding a $30,000 credit card balance while asking for retirement planning advice is like going to a doctor and not mentioning a major symptom.
Emotional Triggers That Drive Impulsive Decisions
Good advisors help you stay disciplined during volatile markets. But if you openly describe the exact scenarios that make you panic, like “I can’t sleep if my portfolio drops more than 5%,” some advisors may use that information to steer you toward products that are more conservative (and more expensive) than you actually need. High-fee annuities and insurance-linked investment products are often sold to anxious investors who could be better served by a simple, low-cost portfolio with a proper asset allocation.
This doesn’t mean you should hide your risk tolerance. That’s a critical part of building a suitable plan. But there’s a difference between saying “I prefer a moderate risk level” and giving an advisor a roadmap to your financial anxieties. Be honest about your comfort level without handing over emotional leverage. If an advisor’s first response to your concerns is recommending a complex product with high commissions, get a second opinion.
Information About Pending Lawsuits or Settlements
If you have a large legal settlement or inheritance on the horizon, be cautious about when and how you share that information. Some advisors may factor expected windfalls into their planning recommendations, encouraging you to take on risk or commit to fee structures based on assets you don’t yet have. Until money is actually in your account, it shouldn’t drive your financial plan.
More importantly, details about pending litigation can create complications. Your advisor’s records could potentially be subpoenaed, and anything you’ve shared about the case or expected proceeds becomes part of a paper trail. Share the facts your advisor needs to do their job, but keep the specifics of legal matters with your attorney.
How to Share What Your Advisor Actually Needs
A good financial planning relationship requires transparency about your real financial picture: your income, assets, debts, tax situation, insurance coverage, and goals. The key is sharing this information through secure channels, at the right time, and without volunteering details that don’t serve your interests.
Before your first meeting, ask the advisor to send a list of what they’ll need from you. Review it on your own time. Gather documents rather than rattling off numbers from memory, which reduces errors and keeps the conversation focused. And before you sign anything, make sure you understand the advisor’s fee structure, how they’re compensated (fees only, commissions, or a mix), and what privacy protections they have in place for your data. Federal rules require them to provide you with a privacy notice that explains how your information is collected, used, and shared with third parties. Read it.
