To see where your Apple ID is logged in, check your device list on an iPhone/iPad (Settings > Your Name), Mac ( Menu > System Settings > [Your Name]), or via the web at account.apple.com/devices; you'll see all devices signed in and can remotely sign out unfamiliar ones for security.
Use your Mac to find where you're signed in
At the top, click Account Details. You can see a list of devices that you're signed in to. The information displayed may vary depending on the device type.
All it's telling you is that, at one point, this device was signed into another Apple ID, and you must transfer it to the new Apple ID. Transfer it, and then don't worry about it.
IP Address: Unlike the Maps app, two-factor verification relies on your IP address to estimate location. This can be misleading if you're connected to a corporate network, VPN, or even a regular ISP where equipment assignments might shift.
Signs that your Apple Account has been compromised
You notice unusual activity, such as messages that you didn't send, deleted items that you didn't delete, account details that you didn't change or don't recognize, trusted devices that you didn't add or don't recognize, or purchase activity that you don't recognize.
iPad / iPhone
Tap on Your Name/Photo in the upper left corner; The email address on the top right is the Apple ID that is currently logged into your device. The other devices that share that Apple ID are shown on the bottom of the window. To sign in with a different Apple ID, click Sign Out at the bottom right.
Remove a device
Technically, no Apple ID has ever been “hacked” (as Apple's servers themselves haven't been compromised at the time of this writing). But there are several ways for scammers to take over your account, including: If your device was stolen or lost. Someone who knows your password used it without your permission.
Run a malware scan
iPhones don't warn users about malware with pop-ups. If you notice signs of malware on your smartphone, run a scan with a trusted tool like Norton Mobile Security. This is the most reliable way to detect malicious software that may have bypassed Apple's defenses and remove it from your device.
How to Tell if Someone Has Remote Access to Your iPhone
Go to your Google Account. Tap Security & sign-in. On the Your devices panel, select Manage all devices. You'll see devices where you're currently signed in to your Google Account or have been in the last few weeks.
An iPhone can be hacked remotely through iOS vulnerabilities. However, it's more likely that it'll be hacked through malicious software or physical access, as programming-based hacking is the most difficult to carry out. Can someone hack my iPhone by calling me? No one can hack your iPhone just by calling you.

Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
Yes, it is possible for a phone to be tapped remotely. Hackers or surveillance programs can gain access through spyware or vulnerabilities in outdated software. Malicious apps disguised as legitimate software can also install tracking tools without physical contact.
On an iPhone, dialing *#21# is a USSD code used to check the status of your unconditional call forwarding, revealing if your calls, SMS, or data are being redirected and to which number, without actually changing settings; it's a simple privacy check to see if someone has secretly set your phone to forward everything, though it doesn't detect advanced spyware. Dialing this code brings up a message from your carrier about your call forwarding status, often showing "Disabled" or a specific number if it's active.
There won't be a history of who used your device, as anyone signing in with your Apple ID is assumed to be you. As you mentioned you can see who is signed in with your Apple ID at appleid.apple.com.
Choose Apple menu , then choose System Settings. Click [your name], then scroll down to see a list of devices.
From the menu bar on your Mac, choose Account > Account Settings. Or on your Windows PC, click your name at the bottom of the sidebar and then choose View My Account. You might need to sign in to your Apple Account. Click Manage Linked Devices.
For iOS, use Apple's Safety Check: To check if your iPhone has been hacked, go to Settings > Privacy & Security > Safety Check. This tool helps you review and revoke the access you've granted to people, apps, and devices, which is a common way iPhones are compromised.
Best thing to do first is change your password for your Apple ID, but before that change the password to the email to your appleID. If someone has your email password, they can just reset the password and lock you out.
Apple Threat Notifications are alerts issued to users who Apple believes have been individually targeted by "mercenary spyware attacks." These are not your average phishing attempts or general malware.
