I noted that 1Password seems to have really good reviews (Mac App Store and CNET) and it seems like a convenient program. I am curious--do many of you use it (or similar apps), and do you not feel nervous about actually putting all your logins/credit card information into one program? I think one thing that makes me hesitant is that it's integrated into the browser--it just seems weird entering a Master Password prompted by Safari or Chrome. On the flip side, I see you can also set it to not prompt you for your Master Password, but to store it in the Apple Keychain. Is that safe? As someone who is relatively new to Macs (and relatively paranoid), I'm not sure I really understand how some of the applications work, including the Keychain. Any advice or feedback would be appreciated.
