Undoubtedly, no one can know today, but in time developers will certainly be able to speak to it. As a long time user of 1Password, I question the security comparison. I think it is open for discussion even though it is likely annoying to compare something that is out there now and something we literally heard of 10 minutes ago. 1Password uses 128-bi AES encryption whereas I believe they said Keychain will use 256-bit AES encryption. Correct me if I am wrong, please. So if you're using Safari on all iOS devices as well as your desktop/laptop etc, then wouldn't this blow 1Password out of the water? Or is there more to it? I've paid quite a bit for 1Password on my iPad, iPhone, and OS X, so I wouldn't mind not having to pay for something if it is more secure and just as easy. One feature I am not a fan of, at least not on the surface, is the password recommendation. Even if I have 1Password installed, I cannot use the password without unlocking 1Password. I don't think I caught, if it was said, Keychain using such security.
