Help protect and secure your information from hackers


Help protect yourself when using an unsecure Wi-Fi connection
Use these tips to help protect yourself when using an unsecure Wi-Fi connection.
  • Avoid connecting to suspicious Wi-Fi networks. Hackers often attempt to trick people by using slightly misspelled Wi-Fi network names or suspicious network names like Free PUBLIC WI-FI. Be especially careful to not connect to personal hotspots or to ad-hoc networks (also known as direct Wi-Fi connections) that you don't know and trust.
  • Use AT&T Mobile Security & Call ProtectFind out how to protect your mobile phone from unsafe apps, files, and nuisance calls.
  • Select apps that use encryption and are well rated in your app store. Some apps may contain holes allowing hackers to access personal and private information found on your wireless device.
  • Use strong passwords. Create strong, highly secure passwords for any services that handle messaging, calling, voicemail, or email accessed through a Web browser from your device.
  • Connect through VPN for optimum security. Learn to connect to a Virtual Private Network (VPN).
  • Verify that you're signing in via the Wi-Fi service provider's authentication page. Be aware of fraudulent Wi-Fi hotspots installed near public hotspots with the same name. These evil-twin hotspots resemble the authentic network sign-in page. If you sign in to a service resembling the authentic network your data may be at risk.
  • Be aware that hackers may be able to monitor your communications. If you are using a compromised network, your personal or private information could be at risk. Use of encryption can help reduce the risks. Always consider the risks when deciding your online activities.
  • Learn to manage Wi-Fi on your device. Learn to manage Wi-Fi on your mobile device every time you're in range of a network.
  • Ensure your Web-based email is secure. While your connection may be highly secure, you'll want to make sure that your individual email message is also secure.

Note: When using AT&T Yahoo! Mail, you'll need to turn on Secure Sockets Layer (SSL) in webmail to encrypt your entire mail session, including the body of the email - otherwise the content of your emails will remain unsecured, even though your connection is secure.

Turn on SSL in your webmail in just a few steps. Once signed in to your email, select Mail Options from the drop-down menu on the top right of the page. Then, in the General section, select Turn on SSL.
