Hey Azin3,

It sounds like you have some concerns about the security of your Apple ID. This information may help:

"Know which Apple ID is signed in to your device

To make sure that you're signed in to Apple IDs that only you control or trust, check the settings on each of your devices.

• Open the Settings app on your iPhone, iPad, iPod touch, or Apple Watch, or System Settings (or System Preferences) on your Mac.
• You should see your name. Tap your name and verify the email address associated with your Apple ID.
• On each of your devices, check the settings for services that you're signed in to with your Apple ID (including FaceTime, Messages, the iTunes Store and the App Store, Internet Accounts, Mail, and Calendar).
• Check iCloud for Windows, your HomePod (using the Home app on your iPhone or iPad), and your Apple TV (for iCloud Photos or Home Sharing).

Make sure that your Apple ID is secure

• If you haven't already, set up two-factor authentication for your Apple ID. This additional security feature is designed to prevent someone else from accessing your account, even if they know your password.
• You should be the only person who knows your password and can sign in with your Apple ID. 
• If someone you don't know or don't trust can sign in with your Apple ID, your account is not secure.
• To help keep your Apple ID secure, you should also keep your device secure and protect your device with a passcode. If someone else has your trusted device and knows your passcode, they can reset your Apple ID passcode. Learn how to secure your device if it's lost or stolen."
