Cybersecurity Tips: Your 12-Step Personal Security Checklist

An unexpected text from your financial institution, a password-reset email you did not request, or a new data-breach notice from a store where you shopped years ago. Most of us have seen these warning signs, and it can be difficult to know which action matters most.

At Credit Union of Georgia, we’re more than your financial partner — we’re committed to keeping your information safe. Protecting yourself and your loved ones from cyber criminals and scams isn’t a once-a-year effort; it’s something we care about year-round. We put together these tips to help you protect your accounts, devices, personal data, and financial information without needing technical expertise.

Which Cybersecurity Tips Can You Put into Practice Today?

You don’t have to tackle everything at once — at Credit Union of Georgia, we know staying secure online can feel overwhelming, so start small. Focus first on the accounts that would cause the most damage if someone gained access, like your primary email, financial accounts, phone account, or password manager, and use the quick-start checklist below to build safer habits at your own pace.

Install a password manager – This reduces the risk that one stolen password unlocks several accounts. Start with your email and financial accounts.
Estimated completion time: 20 minutes.

Enable MFA (Multi-Factor Authentication) on your primary email – This helps protect the account that can reset many of your other passwords.
Estimated completion time: 10 minutes.

Update your phone and computer – Turn on automatic updates to close known security gaps.
Estimated completion time: 10 minutes.

Review account alerts – Alerts can help you spot suspicious transactions or login activity sooner.
Estimated completion time: 7 minutes.

Save recovery codes – Store backup codes for email, MFA, and important accounts in a secure password-manager record or a locked physical location.
Estimated completion time: 2 hours.

Test one backup restore. A backup is only useful if you can actually retrieve a file when you need it.
Estimated completion time: 1 hour.

Save this list somewhere you can revisit every few months, because security isn’t a one-time project; it’s a set of small habits that, over time, can make a major difference in keeping your important information safe.

The Full Checklist: Protecting Every Part of Your Digital World

Now that you know where to start, let’s walk through the full picture. Here are twelve practical steps you can take to protect your accounts, devices, and personal information, explained simply, so you can move through them at your own pace.

1. Use a Password Manager and Give Every Account a Unique Password

When the same password is used on several websites, one breach can become several account takeovers. A criminal may try to use stolen login details on common email, shopping, social media, and financial sites. This is why passwords should be long, random, and unique. A reputable password manager is the practical way to maintain unique credentials at scale. It can generate and securely store a different password for every account, so you do not have to memorize them all.

Your password manager has one especially important credential: the master password. Make it a long passphrase made of several unrelated words that you can remember but others cannot easily guess. Protect the master password with MFA and keep recovery information in a secure location.

Start by changing passwords for:

Your primary email account

Bank, credit union, investment, and payment-app accounts

Your Apple ID or Google Account

Shopping accounts that store payment information

Any account where you reused a password

If a company tells you your information was exposed in a breach, change that password immediately. If you used it elsewhere, change those accounts as well.

2. Turn On Multi-Factor Authentication for Email, Banking, and Social Accounts

Multi-factor authentication asks for a second proof of identity after your password. That may be a code from an authenticator app, a security key, a passkey, or a prompt on a trusted device. Enable multi-factor authentication first on your primary email account. Email is often the key to password resets, meaning control of that inbox can lead to control of many other accounts. Authenticator apps, security keys, and passkeys generally offer more protection against SIM-swap fraud than text-message codes. SMS codes can still be useful when better options are unavailable, but choose an app-, key-, or passkey-based option when an account supports it.

Never share an MFA code with anyone, even if the person claims to be from your bank, a government agency, or technical support. Likewise, never approve an unexpected push prompt. An unexpected prompt may mean someone already has your password and is trying to get past the second step. Save backup or recovery codes offline or in your password manager’s secure records. Those codes can be critical if you lose your phone or computer.

3. Keep Phones, Computers, Browsers and Apps Updated

Updates do more than add new features. They often fix known security flaws that criminals may try to exploit.

Turn on automatic updates for your operating system, browser, apps, router, and antivirus or built-in security software wherever that option is available. Restart your device when prompted so updates can finish installing.

Take a few minutes to check for devices that are no longer supported. An older phone or computer that no longer receives security updates may need to be replaced or used only for low-risk tasks. Also remove apps you no longer use, especially those that have not been updated in a long time.

4. Back Up Important Files and Test the Backup

A lost phone, failed hard drive, accidental deletion, or ransomware attack can take away files that may be impossible to replace. Important records deserve more than one copy.

A good rule of thumb for backups is the 3-2-1 rule:

3 copies of your data

2 different types of media

1 copy stored off-site or offline

For example, you may want to consider keeping your original files on your computer, a copy on an external drive, and another protected copy in a separate cloud backup service.

Prioritize tax documents, family photos, legal documents, insurance records, and critical work files. Cloud sync is helpful, but sync alone is not always a complete backup strategy. If a file is deleted or changed, that deletion or change may sync too. Most importantly, test a restore. Every few months, restore one file to a different folder and open it. Confirm that you can access the backup account and that the file is usable.

5. Spot Phishing Before You Click, Scan, or Reply

Phishing is an attempt to trick you into giving away information, money, or access. It can arrive by email, text, social media, QR code, ad, phone call, or even an AI-assisted voice impersonation.

Common warning signs include:

Urgent language or threats that your account will close immediately.

Requests for passwords, MFA codes, or personal information.

Unexpected payment demands.

Misspellings, unusual grammar, or sender addresses that are slightly off.

Links that do not match the organization named in the message.

A QR code or phone number included in an unsolicited message.

Suppose you receive a text saying your account has suspicious activity. Do not use the text’s link, QR code, or phone number. Instead, independently open the official, type the known website address into your browser, or call the number on your card or statement. This simple verification step is one of the best ways to spot phishing.

If you click a suspicious link, close the page and do not enter information. If you entered a password, change it immediately, review active sessions, and report the message through the platform or organization it impersonated.

6. Lock Down Your Phone and Computer

Your phone may hold MFA codes, your password manager, email, banking apps, payment wallets, and photos of sensitive documents. Treat it like the important access key it is.

Use a strong passcode or password, set a short automatic screen lock, and use biometric unlock when appropriate. Turn on device encryption, which is built into many current phones and computers. Also enable Find My, Find My Device, remote lock, or remote erase before a device goes missing.

On a shared computer, create separate user accounts or profiles. Avoid saving passwords in a browser on a public or shared device. Always sign out when you are done.

7. Install Only Apps and Extensions You Trust

Download apps from official app stores and software from official developer websites. Avoid pirated software, unofficial app downloads, and browser extensions you do not truly need.

Before installing an app, review the permissions it requests. Be cautious when an app wants access to contacts, SMS messages, accessibility controls, your microphone, camera, location, or financial data without a clear reason. Periodically, it’s a smart idea to remove abandoned apps and extensions. Fewer installed programs mean fewer opportunities for a compromised or poorly maintained app to create a problem.

8. Use Public Wi-Fi Carefully

Free Wi-Fi can be convenient, but unknown networks aren’t the place for sensitive banking activity when cellular data or a trusted network is available. Keep these tips in mind:

Confirm the network name before connecting, and turn off auto-join so your device doesn’t automatically connect to lookalike hotspots.

Look for HTTPS to help protect your traffic to a legitimate website — just remember to pair it with good habits, since it works best alongside the other tips here

Consider a VPN for extra privacy on unfamiliar networks and continue practicing safe habits like avoiding suspicious links and verifying MFA prompts, since a VPN works best as one part of your overall security routine.

9. Turn On Account Alerts and Review Transactions

Think of alerts as your early-warning system. When you turn them on for login, transactions, payments, and profile changes, you’ll know right away if something looks off, whether it’s a password change, a new device signing in, or a purchase you didn’t make. Setting these up for your email, financial institution, and payment apps makes it harder for cybercrimes to occur.

It’s also worth making a habit of reviewing your statements and account activity regularly, even for small or unfamiliar charges. Criminals will sometimes run a small test transaction to see if a card works before attempting something bigger, so a charge that looks minor is still worth a second look.

10. Protect Your Credit and Personal Information

A credit freeze restricts access to your credit report, making it harder for someone to open new credit in your name. You’ll need to place a freeze separately with Equifax, Experian, and TransUnion — and keep in mind, it won’t protect your existing bank accounts, credit cards, or other accounts from fraud.

A fraud alert is a lighter-touch option: it asks creditors to take extra steps to verify your identity before opening new credit. It’s typically placed through just one bureau, which then notifies the other two.

We also recommend reviewing your credit and credit reports regularly through Credit Central and AnnualCreditReport.com to help keep an eye out for accounts, addresses, or inquiries you don’t recognize.

11. Keep Financial Information Private

Avoid sharing account numbers, card details, PINs, passwords, or MFA codes through email, text, social media, or an unexpected phone call. Legitimate financial institutions will never ask you to send a one-time security code so they can “verify” your identity.

Be careful with public posts, too. Details such as your birthday, school, hometown, pet’s name, or travel plans can help criminals answer security questions or create convincing impersonation attempts.

When you need help with an account concern, contact your financial institution through a verified number, official website, or trusted app. Do not let an unexpected message choose the communication channel for you.

12. Know What to Do if You Suspect a Compromise

Quick action can limit the damage. If you believe an account, device, or identity may have been compromised, take these steps in order:

1. Secure the account: Change the password from a trusted device and sign out of other active sessions. Review recovery email addresses, phone numbers, forwarding rules, and linked devices.

2. Reset MFA: Remove unfamiliar authentication methods, replace recovery codes, and set up MFA again if needed.

3. Contact financial institutions through verified channels: Use the number on your card or statement, your official banking app, or the institution’s known website. Report unauthorized transactions promptly.

4. Document what happened: Save screenshots, dates, transaction details, messages, and case numbers.

5. Monitor and report identity theft: Review your accounts and credit reports. If personal information was used fraudulently, use IdentityTheft.gov for a recovery plan and reporting guidance. Additionally, place a credit freeze with Equifax, Experian, and TransUnion when new-account fraud is a concern.

You do not need to become a cybersecurity expert to make yourself harder to target. Start with one item today, then return to this checklist until your most important accounts, devices, and records have a stronger foundation. Credit Union of Georgia is here to help members build safer financial habits and recognize fraud before it becomes a larger problem.

Frequently Asked Questions (FAQs)

Are password managers safe to use?

A reputable password manager is generally safer than reusing or memorizing weak passwords because it creates and stores long, unique credentials. Protect the master password with a long passphrase and MFA, and save recovery details securely.

What should I do if I get an MFA prompt I did not request?

Deny or ignore the prompt and do not share any code with anyone, then change the affected account password, review active sessions and recovery details, and contact the provider through its official site or app if prompts continue.

Do I still need antivirus if I keep my software updated?

Yes. Built-in or reputable security software can help detect known threats, but it is only one layer. Updates, cautious downloading, MFA, unique passwords, and backups remain essential.

How often should I back up my files?

Back up important files as often as they change and keep at least one separate off-site or offline copy. Periodically restore a file to verify that the backup works.

How can I tell whether a bank text, email, website or support number is real?

Do not trust contact details or links in an unexpected message. Open the bank’s official app, type its known web address yourself, or use the number printed on your card or statement to verify the request.
