One of my favorite new feature announcements of iOS 12 that will be coming out went largely unnoticed by most people, unless you were really paying attention to WWDC this last year. In the forthcoming release of iOS, Apple is providing new API's to allow password manager apps to be used for the AutoFill function in the OS. This means it will be able to pull from apps like 1Password, rather than requiring that you use KeyChain for your password management.
I personally am a huge fan of 1Password and definitely consider that an app I can't live without. I'm very excited for this feature to be widely available when iOS 12 is released this fall.
