What good is it? Tons.
I got this app back in 2006 as part of the first MacHeist bundle. I thought then, “Hmm, kinda cool I guess.” But as my life has become even more mobile with the use of my iPhone, I quickly realized the need to keep my passwords, and other important info with me where ever I go. A cursory Google search revealed not a WHOLE lot that synced with my mac. 1Password came up on the list as a piece of software that syncs sensitive info between mac and iPhone. I’ve been using it all day today. It’s great. Check it out.
