Hi Dave. Thanks for your response. Based on the recent WSJ articles about iPhone vulnerabilities when stolen if the thief has observed your passcode, I have deleted all my Keychain passwords and now only use 1Password. I'm assuming that the Secret Key is still in the Keychain but not visible. If I turn off Keychain synchronization with iCloud does that go away? It seems to me that in the scenario of a stolen iPhone with stolen iPhone passcode, the fact that the Secret Key is stored in the Keychain would reduce that layer of protection but I guess that is an acceptable and pretty much inevitable risk, given that the thief would still need the 1Password password to access the app. As a separate but related issue, I do think that storing visible passwords in the Apple Keychain creates an unacceptable risk since it would mean that passwords could all be accessed with a 4 digit PIN. Obviously given this situation, it would be a really bad idea to store the 1Password password in the Apple Keychain on an iPhone. Thanks.
