I've used a digital wallet for years to keep track of my passwords (I use Roboform but there are other choices). Recently I found that it serves a purpose that hadn't occured to me: phishing prevention. Here's the deal: I got a message from a friend with a link. Without thinking too much about it, I clicked on the URL and was taken to a fake Twitter homepage asking me to log in. Roboform knew this wasn't a real Twitter page, and so wouldn't log me in. That made me realize that I was being scammed. Thanks, Roboform.
