Be sure to use a VPN you trust if you choose to use one. Provided you do not blindly accept dialogs similar to ' this certificate is bad, do you want to ignore' you should be safe on public wifi as the certificate system can't be altered in transit (at least for good, modern security).Ī VPN can add extra security when using a public wifi network, that wraps all traffic up inside encryption - very similar to https sites but it also handles http sites and other traffic. Be sure to check the site that you login to some banks have many site addresses with different certificates & security levels. tell you how good the bank is dong their job with the certificate & it's security. Others on the same network can see you are sending data to the bank's site but they cannot see what that data is. Ideally your bank uses certificates with good ciphers & extended validation so that anyone on the public wifi cannot attack your traffic.

Https is the security that encrypts your data between the device & the site.
