If you’re receiving notifications that your account has been accessed from a new device, here are some key points and actions you can take:

1. Check Your Password: Make sure your passwords are up-to-date and secure. Choose a unique password for each of your online accounts and change them regularly.
2. Review Your Login History: Monitor your account security settings. Check for any unrecognized IP addresses or countries of origin.
3. Enable Two-Factor Authentication: this added level of security requires both your password and a unique code sent to a device that you own.
4. Take Action: If you're still concerned about the security of your account, contact customer support for further assistance.
