There is nothing that needs to be done. No one is getting any information out of you by visiting your bank account on public Wi-Fi assuming your bank uses https, which is does. It’s not possible. You can’t sniff https traffic which is why chrome yells at you and doesn’t even let you visit some unsecured pages (like if there certificate is invalid). Frankly, the NSA could sniff your https traffic and they couldn’t do anything with it. It’s completely laughable.
