Create a strong password that is easy to remember but difficult to guess. Use your device’s auto-lock feature and set it to take effect five minutes from the last activity. Don’t share your device with others because you can’t set separate passwords.
Install anti-virus software, anti-spyware software, and a firewall. Set your preference to update these protections often. Protect against intrusions and infections that can compromise your mobile device files or passwords by installing security patches for your operating system and other software programs.
Don’t open files, click on links, or download programs sent by strangers. Opening a file from someone you don’t know could expose your device to a computer virus or spyware that captures your passwords or other information you type.
Before you send personal information over your laptop or smartphone on a public wireless network in a coffee shop, library, airport, hotel, or other public place, see if your information will be protected. If you use an encrypted website, it protects only the information you send to and from that site. If you use a secure wireless network, all the information you send on that network is protected.
Back up your data regularly and sync your mobile device with your computer. Delete any text messages or emails that contain sensitive information. Keep financial information on your laptop only when necessary. Don’t use an automatic login feature that saves your user name and password, and always log off when you’re finished. That way, if your laptop is stolen, it will be harder for a thief to get at your personal information.
