Can online password managers be used for storing and managing passwords? I mean from the security point of view. I understand that those systems can be different and some deserves more trust than the other, but what I mean is the whole idea of public service for storing personal passwords. Is it viable in its essence?
About a year ago I signed up for one such service (Passpack). It seems reliable and professional, but I am still afraid to start really using it and upload my numerous passwords there. And it's not because I'm not willing to upgrade to paid account; I'm just very careful and doubtful. Am I wrong?
