When you’re traveling, you may not always have your own laptop or phone with you, which means having to use a public computer at a hotel business center or library.

Public computers can save your search history, your passwords, and sometimes even your credit card information. The next person who sits down could see all of it.

The solution is private browsing, which erases your digital footprints the moment you close the window—no saved passwords and no search history.

On most computers, you can activate it by opening an Incognito window in your browser.

If you want an extra layer of protection, try DuckDuckGo, a search engine that doesn’t track your searches the way Google does.

Whatever you do, never save a password or click “Remember Me” on a public computer.
