I'm a newcomer to 1Password and I'm now set up on my iMac and iPhone. I've created a DropBox account and can sync automatically, without the need to enter anything put the four-digit passcode on my iPhone to start the App. Whilst setting up the sync, I had to enter (what I believe was) the iPhone 1Password Master password for decryption (and I set it to remember) and then the Dropbox password. All went well.
Can you tell me where these two passwords are stored and how are they secured as it seems a risk to store them anywhere on the phone? Thanks.
