How can I prevent account compromise (e.g., MFA)?

Multi-Factor Authentication: MFA significantly reduces compromise risk. Even stolen passwords don't enable access without second factor. Enable MFA on all sending accounts.

Strong passwords: unique, complex passwords for each account. Password managers enable this practically. Avoid password reuse that allows breach cascade.

Security awareness: train users to recognize phishing, verify login pages, and report suspicious activity. Human awareness complements technical controls.
