I see by other commenters, that I'm not the only one who noticed you did not include LastPass.....(Maybe my all time favorite app!)....Why not? Also, Roboform was not mentioned. Are they not in the top 5?....I admit I don't have actual experience with using all of them, but I did do research on most before deciding which to use, and I found that many of them, unlike LastPass, don't offer in their frees versions unlimited storage, as well as a great many useful features that would you would need to pay for in some of other programs....In fact I feel guilty about not getting the paid version of LastPass, since I rely on it so heavily! (I have well over 600 passwords and secure notes, as well as many other things stored.) I keep telling myself I will upgrade eventually...I love this app, I cannot say enough good things about it!.... As for it's security measures, I have great confidence, after doing much research and reading many independent evaluations by some very qualified people....Kevin.
