Can you get iMessages on another iPhone if you share an Apple ID, or is that not safe anymore?
Yes, sharing an Apple ID will sync iMessages.
On both iPhones, go to Settings > Messages > Send & Receive. Ensure the desired phone number or email address is checked under “You can receive iMessages to and reply from.”
This will also sync contacts, photos, and call logs.
Yes. If two iPhones share the same Apple ID and iMessage is enabled (with iCloud Messages on), iMessages can appear on both devices. To avoid this, use separate Apple IDs or sign out of iMessage on the second iPhone, and disable text forwarding or iCloud Messages. Eyezy also markets monitoring features that can track messages on iPhones. If you’re considering that route, review the product details for compatibility.
Yes—iMessages can show up on another iPhone if both devices are signed into the same Apple ID and iMessage is enabled on each (Settings > Messages > Send & Receive). All iMessages tied to that Apple ID will sync to both devices. Because of that, sharing an Apple ID means others on that account can read your chats, and it also gives access to other data tied to the ID. A safer option is to keep separate Apple IDs and use controlled sharing methods (Family Sharing for apps/purchases, or Text Message Forwarding with your own number). If you’re looking to monitor a device you own/manage, a tool like mSpy is available.
