Sign into or out of FaceTime on Mac
Sign into FaceTime
You need to sign into FaceTime the first time you open the app or if you’ve signed out.
In the FaceTime app on your Mac, enter your Apple ID and password.
Click Next. FaceTime is on automatically.
If you forgot your Apple ID or password or if you need to create an Apple ID, go to the Apple ID account website.
Make sure to sign in using the same Apple ID on every device. See the Apple Support article Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch.
Sign out of FaceTime
When you sign out of FaceTime, you can’t receive FaceTime calls or phone calls until you sign in again.
In the FaceTime app on your Mac, choose FaceTime > Preferences, then click Settings.
Click Sign Out.
Turn FaceTime on or off
If you want to stay signed into FaceTime but stop receiving calls, you can turn off FaceTime. If someone calls you, you won’t receive a notification for the call; to the caller, it looks like you’re not available.
In the FaceTime app on your Mac, do one of the following:
Turn off FaceTime: Choose FaceTime > Turn FaceTime Off.
Note: Instead of turning off FaceTime, you can turn on Do Not Disturb in Control Centre, which prevents notifications from disturbing you. See Use Do Not Disturb.
Turn on FaceTime: Choose FaceTime > Turn FaceTime On.
Note: To block all FaceTime or phone calls, turn off FaceTime or sign out of FaceTime on each device. (You can also block individual callers. People who are on your blocked list are blocked on all of your devices signed into FaceTime and iCloud using the same Apple ID.)
