Two-factor authentication is an extra layer of security designed to ensure that you’re the only one who can access your accounts, even if someone knows your password. It typically involves something you possess, like a phone or cell phone, and something you are, like a fingerprint scan or eye scan.

1. Enable two-factor authentication on your accounts, for increased security.
2. Set up an alarm on your phone or email account if suspicious activity is detected.
3. Check passwords against publicly available data breaches to see if they have been leaked.
4. Create strong passwords that are not easily guessed by finding out personal details about you.
5. Practice good online security habits, such as not clicking on links from unknown sources.
6. Keep backup copies of important data stored securely.
7. Make sure you install firmware updates and security patches regularly.
