Fill in info from Contacts
In the Safari app
on your Mac, start typing any name from your contacts to autofill their details.If a contact has more than one address, email, phone or other contact info, you can choose from the home, work or custom address you’ve already entered in their contact card (or use the Touch Bar). If you don’t want Safari to autofill information, just keep typing.
Important: Safari autofills your information for anyone who uses your Mac with your user login. It also autofills your information for anyone who uses your other devices, if those devices and your Mac have iCloud Keychain set up.
For security, set up your Mac to display the login window when it starts up and to require a password after sleep or a screen saver begins. Also set up your iPhone, iPad and iPod touch to require a passcode to unlock the screen.
