Do you clear your cache after you use online banking? I've been looking around and it seems like this is a wise protocol to follow. Does anyone know how I would do it?
It depends on what browser you are using, but yes, I would recommend clearing your cache. You can check wherever your tools option is for emptying out your history. It should be there.
Clearing your cookies and cache after visiting any site where you have input personal information is always a wise thing. This reduces the risk of someone stealing your information.
Clearing the cache and cookies is not just good with online banking but also good for all your online accounts. If someone hacked your email then they could also open your bank account.
