Don’t over share on social networking websites. Keep Social Security numbers, account numbers, and passwords private, as well as specific information about yourself, such as your full name, address, birthday, and even vacation plans.

The United States Computer Emergency Readiness Team (US-CERT) recommends locking your device when you are not using it. You might only step away for a few minutes, but that’s enough time for someone to steal or destroy your information. Use strong PINs and passwords to prevent others from accessing your device.

If you ever forget a password, you’ll likely reset it by having a link sent to an on-file email address. Make sure that that account is secured with two-factor authentication, doesn’t have any unusual forwarding filters set up and allows for global sign-out in case someone else accesses it.

Review your banking, credit card, or payment service statements regularly to ensure there are no unauthorized charges or withdrawals. Be sure to shred bank and credit card statements before throwing them in the trash; talk to your bank about using passwords and photo identification on credit cards and bank accounts.

It’s likely someone has asked for your Wi-Fi password when visiting your home. A more convenient and safer alternative than giving it away is to set up a guest Wi-Fi connection. Guest networks can be left open, plus they isolate their traffic from your main SSID, which can prevent the spread of malware.

What if you left your phone behind in a public place? Without a passcode on the lock screen, its contents would be fully accessible to anyone who had it. Configure a passcode, along with other even more secure options such as a fingerprint or facial recognition scan, if available on your device.
