Is Public Wi-Fi Safe for Your Sensitive Accounts?
Is public Wi-Fi safe for your sensitive accounts? The FTC says it usually is today, because most websites now use encryption to scramble your data. Its consumer page states: "Because of the widespread use of encryption, connecting through a public Wi-Fi network is usually safe." Before you log in, look for a lock symbol or https in the address bar. One caution remains: encryption does not make a scammer's website safe.
What do the official pages say about public Wi-Fi?
When you connect to a website, information travels from your device to that site. The FTC consumer page on public Wi-Fi notes that this "could include sensitive data like the log in information for your financial, email, or social media accounts."
The page also explains what changed: "In the past, if you used a public Wi-Fi network to get online, your information was at risk." Back then, most websites did not use encryption, so the data was not protected from hackers snooping on the network. Today most websites do use encryption, and that widespread use is the reason the FTC gives for calling a public connection usually safe.
How can you tell that a connection is encrypted?
The FTC gives a simple sign to check: "Look for a lock symbol or https in the address bar to the left of the website address." It adds: "This works on a mobile browser, too." Apps are less clear. In the FTC's words: "It can be hard to tell if a mobile app uses encryption, but the majority do."
What is not safe, even with a lock symbol?
The lock tells you that data is encrypted on its way to a site. It does not tell you that the site is honest. Scammers pretend to be someone they are not, such as a representative from a well-known company or the government, and they also create fake websites and encrypt them to make you think they are safe. On a scammer's site, the FTC explains, "your data may be encrypted on its way to the site," but it will not be safe from the scammers who operate the site.
For sensitive accounts on any network, that leads to a few practical habits:
- Check the address bar for a lock symbol or https before you type a password.
- Do not rely on the lock alone. A fake site can be encrypted too.
- Do not click a link in an unexpected email or text. The FTC says: "Instead, contact the company using a phone number or website you know is real."
Which steps protect your accounts on any network?
The FTC says that no matter how you get online, it is always a good idea to take some steps to protect your personal information. The two official pages point to these:
- Strong passwords. "Create and use strong passwords and turn on two-factor authentication" when it is available. For a password you make yourself, make it long: "Aim for at least 15 characters." The pages also mention a passphrase of random words, a password your browser or device generates, or a password manager.
- Two-factor authentication. It "adds an extra layer of security to your account." The most common type is a one-time passcode by text message or email. The page adds: "The more secure types of two-factor authentication are an authenticator app or a security key."
- Updates. Keep your security software, operating system and internet browser up to date, update your phone's operating system too, and "turn on automatic updates to keep up with the latest protections."
What if something goes wrong?
The FTC says it is important to act quickly if you discover an issue. You can report scammers to the FTC at ReportFraud.ftc.gov, and "if you think someone is using your personal information, go to IdentityTheft.gov to report it and get a personalized recovery plan."
What is not covered or depends on the situation?
The cited pages do not name specific network tools or settings for a particular cafe, hotel or airport network. They also leave some points open: whether a given app encrypts your data can be hard to tell, and a lock symbol does not prove that a site is genuine. If you are unsure whether a site is real, our guide on how to spot a fake immigration website covers warning signs, and our page on how to protect your Social Security number covers another sensitive detail.
