The core steps that stop most account theft
Most bank account theft happens through one of three routes: someone guesses or buys your password, someone tricks you into giving them access, or someone intercepts your login when you use public WiFi. You can block all three by using a strong password that only you know, turning on two-factor authentication (a second verification step after you enter your password), and never entering your banking information on public networks.
These three actions stop the majority of hacks. Everything else in this guide builds on them. If you do only these three things, your account is far safer than most.
Key Takeaways
- A strong password is one you have never used anywhere else, contains uppercase and lowercase letters plus numbers and symbols, and is at least 12 characters long.
- Two-factor authentication requires a second proof of identity — usually a code sent to your phone — before anyone can log in, even with your correct password.
- Public WiFi at coffee shops and airports is not encrypted, so anyone nearby can see what you type; use your phone's data plan or a VPN instead.
- Your bank will never ask for your password, PIN, or full account number by email, text, or phone; if someone does, it is a scam.
- Checking your account regularly and setting up transaction alerts means you notice theft within hours instead of weeks.
Creating a password that hackers cannot guess or crack
A password is the first lock on your account. Most passwords fail because they are either too straightforward (like "password123" or your birth year) or reused across multiple sites. If a hacker breaks into one website you use, they try that same password on your bank account.
A strong password for your bank account should be at least 12 characters long and contain uppercase letters, lowercase letters, numbers, and symbols like ! or #. An example might be "BlueMoon$47!Desk" — random enough that it is not based on your life, but memorable enough that you can type it without writing it down. The key rule: never use this password anywhere else. Your bank password should be unique to your bank.
If you have trouble remembering a long unique password, use a password manager — a locked app or website that stores passwords for you. You remember one strong master password, and the manager remembers the rest. Common password managers include Bitwarden (free), 1Password, and LastPass. Your bank may also offer a password manager built into its app.
Turning on two-factor authentication at your bank
Two-factor authentication, often called 2FA or two-step verification, requires a second proof that you are you before you can log in. Even if a hacker has your correct password, they cannot get into your account without this second factor.
The most common second factor is a code sent to your phone by text message (SMS). When you log in from a new device or location, your bank sends a six-digit code to your phone. You enter that code on the login screen. Only someone with your phone can complete the login. Some banks also offer an authenticator app — an app on your phone that generates codes without needing a text message. This is slightly more find because codes are not sent over text, which can be intercepted.
To turn on two-factor authentication, log into your bank account online or in the app, look for "Security" or "Account Settings," and find the option for two-factor authentication or two-step verification. Your bank will ask you to confirm your phone number or read an authenticator app. Once it is on, you will use it every time you log in from a new device.
Protecting yourself on public WiFi and shared computers
Public WiFi at coffee shops, airports, and libraries is not encrypted. Anyone with basic technical knowledge sitting nearby can see everything you type — including your password and account number. Never log into your bank account on public WiFi.
If you must bank from outside your home, use your phone's data plan instead of WiFi. Your phone's data connection is encrypted and much safer. If you are on a computer without a data plan, wait until you are home on your own WiFi.
If you use a shared computer — at a library, a friend's house, or a workplace — never save your password when the browser asks. Log out completely when you are done, and clear your browser history. Better yet, use your phone instead. Shared computers are higher risk because other people who use them may have installed malware (harmful software) without anyone knowing.
Recognizing and avoiding scams that steal your login information
Hackers often do not try to crack your password. Instead, they trick you into giving it to them. This is called phishing. A phishing scam usually arrives as an email or text that looks like it is from your bank, asking you to "verify your account" or "confirm your information" by clicking a link.
Your bank will never ask for your password, PIN, full account number, or Social Security number by email, text message, or phone call. If you receive a message asking for any of these, it is a scam. Do not click the link. Instead, go directly to your bank's website by typing the address into your browser (not by clicking a link in the email), log in, and check your account. If something is wrong, your bank will tell you when you log in.
Scammers also call pretending to be from your bank's fraud department, saying they detected suspicious activity and need you to "verify" your information. Hang up. Call your bank directly using the number on the back of your debit card or on your bank statement. That way you know you are calling the real bank, not a scammer.
Monitoring your account so you notice theft quickly
Even with strong security, theft can happen. The difference between a minor problem and a major one is how fast you notice. Check your account at least once a week — look at your recent transactions and make sure you recognize every charge.
Most banks offer transaction alerts, which send you a text or email notification when money leaves your account. You can usually set alerts for any transaction over a certain amount, or for all transactions. Turn these on. If a hacker gets into your account, you will know within hours instead of weeks.
If you see a transaction you did not make, contact your bank when ready. Most banks have a fraud department that works 24 hours. Tell them which transaction is not yours. They will investigate and usually reverse the charge within a few days. The sooner you report it, the faster they can act.
What to do if you think your account has been hacked
If you notice unauthorized transactions, cannot log in, or receive a notification about a login from a location you were not in, contact your bank right away. Call the number on the back of your debit card or on your statement — not a number from an email or text message.
Tell your bank what happened. They will lock your account, reverse fraudulent charges, and issue you a new debit card. They may also ask you to change your password and turn off any saved payment methods. Follow their instructions exactly.
If the hacker also changed your password or email address, you may not be able to log in yourself. That is fine — your bank can still help you. They can verify your identity by asking security questions or other information only you would know, and they can regain control of your account for you.
Frequently Asked Questions
Is it safe to save my password in my browser?
Only if you are the only person who uses that computer and you always lock it when you step away. If anyone else uses the computer, or if you use a shared device, do not save your password. A password manager on your phone is safer because it is encrypted and requires its own password to open.
What if I get a text from my bank asking me to click a link?
Legitimate banks sometimes send text alerts about your account, but they rarely ask you to click a link. If you are unsure, do not click. Instead, call your bank using the number on your debit card and ask if they sent the message. If they did, they can tell you what it was about.
Can my bank see my password?
No. Your bank stores an encrypted version of your password, not the actual password. Even bank employees cannot see it. If you forget your password, your bank cannot tell you what it is — they can only send you a link to create a new one.
Do I need to change my password regularly if I have a strong one?
Not unless your bank requires it or you think someone may have seen it. Changing a password you have not shared does not make it stronger. Focus instead on keeping it unique, strong, and secret.
What is a VPN and do I need one?
A VPN (virtual private network) encrypts everything you do on public WiFi, making it as safe as your home network. You do not need one if you use your phone's data plan instead of WiFi, but it is useful if you travel often and must use public networks. Free VPNs exist, but paid ones like ExpressVPN or NordVPN are more reliable.
