To improve online privacy, avoid posting details that 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 independently, review app permissions, and protect accounts with unique passwords and multifactor authentication.
What personal information should you avoid sharing publicly?
Keep details that could identify, locate, or target you out of public posts. CISA advises limiting what you share on social media, including your address and places you frequent.
- Do not publish account numbers, passwords, Social Security numbers, or other account credentials.
- Avoid posting your home address, full name, or birthday where anyone can see it.
- Do not announce vacation plans or share your real-time location publicly.
- Review location services and turn off access that reveals where you are when an app does not need it.
Privacy settings can narrow who sees a post, but they cannot prevent someone in the audience from copying or redistributing it. Treat anything shared with an audience as potentially shareable beyond that audience. CISA’s Online Privacy Tip Sheet offers additional guidance.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should you do about unexpected links and messages?
Do not click an unexpected link or attachment or submit private information just because a message looks like it came from a familiar organization. Phishing messages can appear convincing, and scammers may direct people to fake websites.

Which app permissions should you avoid granting?
Do not give an app access that does not make sense for its purpose. For example, consider why a basic utility would need your location or contacts before approving that access.

Use the privacy or app-permission controls on your device to make these changes; the exact labels and paths vary by operating system and version. CISA’s Online Privacy Tip Sheet recommends checking permissions and limiting access to what an app needs.
Is public Wi-Fi safe, and what should you avoid?
Public Wi-Fi is not automatically unsafe. The FTC says that because encryption is widespread, connecting through public Wi-Fi is usually safe. Still, confirm that you are joining the venue’s real network, and do not assume that either a network name or an HTTPS lock proves a destination is trustworthy.

Avoid reusing passwords across accounts and relying on a password alone when an account offers multifactor authentication (MFA). Use a strong, unique password for each account, and enable MFA where available. Keep your operating system, browser, and security software current, as the FTC recommends in its online privacy and security guidance.

Choose an MFA method the account supports
MFA methods do not all offer the same protection. CISA identifies FIDO2 security keys as phishing-resistant, but whether you can use one depends on the account and device. Check the service’s own setup instructions before choosing a method.

Before relying on a security key or another MFA device, review how the service lets you recover access if it is lost. CISA’s October 2022 guidance on phishing-resistant MFA is written primarily for organizations; its discussion of FIDO2 does not establish that every consumer account supports security keys.
