Avoid accessing confidential information
When connected to public Wi-Fi, don’t log on to banking or similar apps, and don’t use apps or sites that involve personal, sensitive or confidential data. That goes for email too.
Beware who’s ‘listening’
Why? The danger of public Wi-Fi is that someone on that network may be “listening” to the information and data streaming back and forth from your device. That data could potentially be used to go back and access your accounts or other personal information.
Delete your profile when you’re done
Just because you log on to a public Wi-Fi network doesn’t mean you want to every time you’re near it. Once you’ve finished using a network, make sure you log out and then delete the public Wi-Fi network from the list of networks on your phone or device.
If you don’t, your device could log on automatically next time you’re nearby, even when you don’t want it to. That puts you at risk for inadvertently sharing personal or confidential information.
