Multi-Factor Authentication for Admin and Hosting Accounts

Multi-factor authentication adds a second proof of identity beyond a password. It is especially valuable for accounts that control domains, hosting, email, source code, payment systems, and customer data.

Prioritize privileged accounts first, then extend coverage to staff and customer accounts according to risk. Prefer phishing-resistant security keys or passkeys where supported. Authenticator apps are often a practical improvement over password-only login, while SMS has known limitations and may be vulnerable to number takeover.

Recovery must be designed carefully. Provide backup codes or an administrator-assisted recovery process with identity checks, and protect recovery codes as secrets. Do not let a weak recovery channel completely bypass the stronger primary authentication method.

Review sessions and active devices, revoke access when staff leave, and ensure emergency access is documented and audited. Test the process before enforcing MFA for all administrators. Strong authentication is most effective when paired with unique passwords, least privilege, and alerts for unusual login activity.
