Has anyone heard of this or tried it before? It sounds great for security, but could get rather annoying to have to go through this process every time you need to log in to a Wordpress admin account. Long story short: it's a free plugin that connects to PhoneFactor. Every time you log in, PhoneFactor calls your phone. You then press # and you're granted access to your Wordpress site, making it impossible for hackers to ever get in.
