With iOS 17, you can share an AirTag location and Find my Device with your family and others. Before iOS 17, you could only use an AirTag with a single Apple ID.
Here’s how to share an AirTag location with others:
° Launch the Find My app on your iPhone.
° Tap the Items tab.
° Tap on your AirTag’s name.
° Swipe up to show the Share This AirTag option.
° Now you can choose to Add Person > Continue.
° Tap the name of the person on your Contacts with whom you want to share your AirTag locations.
° Tap Send. The person is added to a list of folks with whom you’re sharing your AirTag location.
If you want to stop sharing your AirTag’s location, tap on the name of the contact again, then tap Remove.
