Staying safe while using public wifi
You should avoid using public wifi to access mobile or online banking. The majority of public wifi networks are not securely encrypted and because of that, they’re not private.
This includes public wifi that prompts you to log in by entering an email address, like @pubname, @restaurantname or @gym. Although this may feel more official, it simply allows the business owner to use data analytics on customers and is no more secure than other public wifi.
Public wifi makes it easy for someone to see your online activity. This can include capturing your PIN, passwords and viewing sensitive email or financial transactions. You should use mobile data on your 4G or 5G provided network to access mobile banking.
