To improve online privacy, avoid publicly sharing details that can identify or locate you, clicking unexpected links, granting apps unnecessary access, reusing passwords, and treating public Wi-Fi or an HTTPS lock as proof that a website is trustworthy. Share less, verify messages and networks independently, review app permissions, and protect accounts with unique passwords and multi-factor authentication (MFA).
What should you avoid posting publicly?
Personal details can help others identify, locate, or target you. CISA advises limiting what you post on social media, including personal addresses and places you frequent. Keep these details private:

- Home addresses, account numbers, passwords, and Social Security numbers.
- Birthdays and other details that could help identify you or answer account-security questions.
- Real-time location, places you regularly visit, and travel or vacation plans.
Review location-sharing settings and disable location services that reveal where you are when you do not need them. Privacy settings can limit who sees a post, but they cannot ensure that an audience will not copy or redistribute it. CISA’s Online Privacy Tip Sheet offers further guidance.
What should you do about unexpected links and messages?
Do not click an unexpected link or attachment, reply with private information, or enter account details just because a message appears to come from a familiar organization. Phishing messages can look credible, and scammers may imitate trusted organizations or direct people to fake websites.

The FTC’s phishing guidance explains how to recognize and avoid these scams.
Which app permissions should you avoid granting?
Do not grant an app access that does not make sense for what it does. An app may access information or features in the background after you approve a permission, so review permissions periodically and remove apps you no longer use. Install apps from trusted sources, and reconsider whether an app is worth keeping if its requested access seems unrelated to its purpose. CISA covers app permissions and privacy in its Online Privacy Tip Sheet.

Is public Wi-Fi safe?
Public Wi-Fi is not automatically unsafe: the FTC says that, because encryption is widely used, connecting through a public Wi-Fi network is usually safe. Still, verify the network name and login method with venue staff, use websites that show HTTPS, and avoid sensitive activity on a network you do not trust. The FTC explains this updated context in Are Public Wi-Fi Networks Safe? What You Need To Know.
HTTPS encrypts information in transit, but it does not prove that the site itself is honest. A scammer can operate an encrypted website. Check that you are visiting the intended organization before entering sensitive information; an HTTPS lock alone is not a trust check.

What account-security habits should you avoid?
Avoid reusing passwords across accounts and relying on a password alone when a service offers another sign-in factor. Use strong, unique passwords and enable MFA wherever it is available. Keep your operating system, browser, and security software current; the FTC’s consumer guidance includes these account and software precautions.
Choose an MFA method the account supports
MFA options differ in how well they resist phishing, how convenient they are, and how you can recover access if a device or key is lost. CISA identifies FIDO2 security keys as phishing-resistant, but a key helps only for accounts that support it. Check the service’s setup and recovery instructions before relying on a particular method. CISA’s October 2022 fact sheet on phishing-resistant MFA is written mainly for organizational leaders; its assessment of FIDO2 should not be read as a consumer compatibility guarantee.
