Why one code stops most attacks
The majority of unauthorised access attempts rely on stolen or reused passwords — not sophisticated techniques. Two-factor authentication (2FA) breaks this chain: even if a password leaks, an attacker still cannot sign in without the second factor.
For pages and business assets managed by teams, 2FA also creates a clear checkpoint: every new sign-in from an unrecognised device must satisfy a second, physical challenge.
Choosing the right method
Not all second factors offer equal protection. Security keys and authenticator apps are materially stronger than SMS codes, which can be intercepted through SIM-swap attacks. Where a platform offers multiple options, prefer a hardware key or app-based factor for administrators.
- Hardware security keys: strongest, best for high-value admin accounts
- Authenticator apps: strong and practical for most teams
- SMS codes: better than nothing, but weakest against interception
Recovery codes are part of the control
A 2FA setup is incomplete without a recovery plan. Store backup codes securely — a password manager or a locked physical location — and ensure more than one trusted person can recover access if an administrator becomes unavailable. Losing the second factor on a business-critical account creates its own continuity incident.
Making it stick across a team
For organisations with several administrators, individual 2FA is not enough; the admin structure itself needs review. Remove dormant accounts, define who may hold admin roles, and re-verify access when staff changes happen. Vanguard IT's security strengthening support covers this end-to-end, from 2FA rollout planning to full access-governance review.
