Secure your device before logging into financial accounts

Everything begins with the device in your hands. If it isn’t secure, even the strongest password can be exposed. These essentials help lock things down before you ever sign in.

Start with these device security basics:

• Keep your phone, tablet and computer fully updated with the latest operating system and browser versions
• Use strong, always-on antivirus protection to block malware and phishing attempts. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.
• Avoid public Wi-Fi when accessing financial accounts, or use a trusted VPN if you have no other option.  For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices at Cyberguy.com.

Protect your bank and investment account logins

Your login details are the front door to your money. Strengthening them reduces the chance that anyone else can get inside.

Strengthen your account logins by:

• Using strong, unique passwords for every financial account
• Avoiding saved passwords on shared or older devices
• Relying on a password manager to create and store credentials securely. Our No. 1 pick, includes a built-in breach scanner that alerts you if your information appears in known leaks. If you find a match, change any reused passwords immediately and secure those accounts with new, unique credentials.
• Checking whether your email or passwords have appeared in known data breaches and updating reused passwords immediately. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.
• Turning on two-factor authentication (2FA) wherever it’s available

Avoid common online banking scams when logging in

Even well-secured accounts can be compromised through careless access. How you log in matters.

Reduce your risk when accessing financial accounts:

• Typing website addresses yourself or using saved bookmarks
• Avoiding login links sent by email or text, even if they look official
• Checking for “https” and the lock icon before entering credentials
• Logging out completely after every session, especially on mobile devices

DON’T LET AI PHANTOM HACKERS DRAIN YOUR BANK ACCOUNT

Think of these as early warning systems. They help catch problems quickly, before real damage is done.

Enable financial account alerts and safeguards:

• Setting up alerts for logins, withdrawals, password changes and new payees
• Requiring extra confirmation for large or unusual transactions
• Freezing your credit with the major credit bureaus to block new accounts opened in your name. To learn more about how to do this, go to Cyberguy.com and search “How to freeze your credit.” 

Protect your identity beyond your bank accounts

Your financial accounts are only part of the picture. Identity protection helps stop problems before they ever reach your bank.

Go beyond basic banking security:

• Monitoring for identity theft involving your Social Security number, phone number and email
• Using an identity protection service that alerts you if your data appears on the dark web or is used fraudulently. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com
• Removing your personal information from data broker websites that buy and sell consumer data. A data removal service reduces risk before identity theft happens.

Review bank and credit statements for early warning signs

Review your bank, credit card and investment statements regularly, even when nothing looks suspicious. Small red flags often appear long before major losses.

Everyday security habits that prevent financial scams

Many successful scams rely on pressure and trust, not advanced technology. Good habits close those gaps.

Practice smart daily security habits:

• Never allow anyone to log into your accounts remotely, even if they claim to be from your bank
• Avoid storing photos of IDs, Social Security cards, or account numbers on your phone or email
• Stop immediately if something feels off and contact the institution directly using a verified phone number

Kurt’s key takeaways

Checking your bank or retirement accounts online should feel routine, not risky. With updated devices, strong logins, careful access and smart habits, you can keep control of your money without giving up convenience. Security is not about fear. It is about staying one step ahead.
