Like on an airplane or in an airport, hotel, train/bus station or café-be sure to confirm the name of the network and exact login procedures with appropriate staff to ensure that the network is legitimate. Using your mobile network connection is generally more secure than using a public Wi-Fi network.

Turn off features on your computer or mobile devices that allow you to connect automatically to Wi-Fi. Once you’ve finished using a network or account, be sure to log out.

Be cautious about what you do on public Wi-Fi, and use a VPN if possible. Another option is to look for semi-public networks, i.e. ones with passwords that are provided by staff or on printed receipts, like at restaurants or coffee shops. Up-to-date security software is also a must-have to shield you from any malware […]

All other wireless encryption methods are outdated and more vulnerable to exploitation. In early 2018, the Wi-Fi Alliance announced WPA3 as a replacement to the longstanding WPA2 wireless encryption standard. As WPA3-certified devices become available, users should employ the new standard.

When shopping online, get the maximum possible security and privacy for your transactions. That means never buying anything while connected to public or open Wi-Fi networks, or even to the Wi-Fi of someone you don’t know well. Stick to your own Wi-Fi or to cellular service like LTE for the safest results.

Networks without passwords do not encrypt your connection. Accordingly, it’s possible for other connected users to spy on your activity, including any password you type. Don’t view your bank balance or log into any accounts tied to a debit/credit card while on public Wi-Fi. Cellular is much safer in these cases.
