Use Sign in with Apple on Mac
Sign in with Apple is an easy and private way to sign into apps and websites. It uses your Apple ID to securely create an account with an app or website—no need to fill out a form, verify your email address, or choose a new password—and simplifies signing in each time.
Create an account for an app or website
On your Mac, when you’re asked to create an account for an app or a website, click the button to sign in or continue with Apple, if available.
Follow the onscreen instructions, keeping the following in mind:
If you don’t want to use your real name, click the Name field, then enter a different name.
If you have more than one email address associated with your Apple ID in Apple ID preferences, choose which email to use for the app or website.
If you prefer to keep your email address private, click Hide My Email. Apple generates a random and unique email address that’s used to forward emails from the app or website to your real email address.
Sign in to your account for an app or website
On your Mac, click the button to sign in or continue with Apple.
Enter your login password on your Mac (you may need to enter your Apple ID password instead) or, if your Mac or Magic Keyboard has Touch ID, use Touch ID.
You can also sign in from your other devices—iPhone, iPad, Apple Watch, and Apple TV—where you’re signed in with the same Apple ID.
Change the address used to forward email from apps and websites
If you chose to hide your email when you created an account, and you have more than one email address associated with your Apple ID in Apple ID preferences, you can change the address that receives forwarded email.
On your Mac, choose Apple menu
In the sidebar, click “Name, Phone, Email,” then click Edit next to Hide My Email.
Choose a different email address, then click Done.
Change Sign in with Apple settings for an app or website
On your Mac, choose Apple menu
In the sidebar, click Password & Security, then click Edit next to Apps Using Your Apple ID.
Click an app or website in the sidebar, then do any of the following:
Turn off forwarding email: Click Turn Off. You won’t receive any further emails from the app or website.
Stop using Sign in with Apple: Click Stop Using Apple ID. You may be asked to create a new account the next time you try to sign in with the app or website.
