Checking breach databases...
A data breach is an unauthorized access to sensitive information held by an organization. Breaches can expose personal data like emails, passwords, credit cards, and other sensitive information.

If your email is found in a breach, you should: 1) Change your password immediately, 2) Enable two-factor authentication, 3) Monitor your accounts for suspicious activity, 4) Consider using a password manager.
