Modify your Credentials:

If you think your account have compromised, then most certainly consider modifying your credentials, for Security & Privacy concerns, starting with a new password. Here is how it would work with Apple:

• Modify: your login credentials (Using Both a New eMail and a New Passwordfor each and all sites)
• Associate: a different method of payment to your account
• Enable: Two-Factor Authentication for Apple ID and for all other accounts that have such an applicable option
