Keychain
One password to rule them all.
Let's be honest, when Apple introduced Keychain, they just added it to the keys and certificates developer tool on macOS without creating any new interface.
Sad right? Because Keychain could be a great built-in alternative to third-party password managers. With a first step in this direction from Apple with iOS 12, I decided to design a concept of what could be a more user-friendly UI integrated in System Preferences.
