How secure is public Wi-Fi?
We generally suggest that you avoid public wireless networks to access your Hargreaves Lansdown account. Public Wi-Fi networks either do not require authentication at all or require a password which is the same for all its users, both of which create a playing field for fraudsters who can target unsuspecting individuals and glean precious information floating in an unsecured environment. Turn off Wi-Fi when you are not using it which will prevent your device from automatically connecting to networks.
Please remember that changing your passwords regularly is one of the most effective ways to ensure the safety of your accounts. If you have accessed your Hargreaves Lansdown account in a public Wi-Fi zone, next time you are within your secure connection consider changing your password.
