Having spent a bit of time with High Sierra and iOS 11, I've noticed an opportunity to smooth out the relationship between keychain and 1Password. While I know that keychain sync has come up before in the context of import and has been dismissed due to friction in the UX (having to approve access for every item), I'd love to see an option to sync individual items to keychain so that I can more easily take advantage of Apple's new password entry features for items that I'm willing to entrust to keychain. While I could perform the manual task of copying these items to the OS keychain, I'd much rather manage everything through 1Password and have the sync happen behind the scenes.
Depending on how completely this feature is fleshed out, I see some other benefits as well. The most significant in my mind is 1Password is positioned to provide a better keychain sync (relative to iCloud Keychain). When I bring up the vault on a new device, the items that are designated for sync would be added from 1Password to the local macOS or iOS keychain. Even better if 1Password can also detect new items in keychain, e.g., wireless networks, and give me the opportunity to bring that into my Vault (the one-time prompt for permission is not a major burden when working with individual items).
Any chance AgileBits has given this some thought already? Having worked a bit with the new CLI and native keychain interfaces, I feel pretty confident that there aren't any major technical or cryptographic obstacles. Likewise, I think there's an opportunity to provide an even smoother end-user experience and spin 1Password as a "better" front-end to Keychain Access.
