Definition

Two-factor authentication (2fa) deals with how users, devices and applications prove who they are and what they are allowed to do. It is central to protecting accounts, sensitive data and critical systems from misuse.

Strong processes and tools around two-factor authentication (2fa) reduce the chance of account takeover, insider abuse and unauthorised changes, and they are a key building block for zero‑trust security models.

Used Cases

  • Designing account and access models that rely on two-factor authentication (2fa).
  • Reducing unauthorised access to critical systems by enforcing two-factor authentication (2fa).
  • Supporting audit and compliance checks that review how two-factor authentication (2fa) is applied.

FAQs

Why is two-factor authentication (2fa) a key part of protecting accounts and access?

Two-factor authentication (2fa) helps confirm who a user or device is and what they are allowed to do. Strong identity controls reduce the chance that stolen credentials or misused accounts will lead to a breach.

How does two-factor authentication (2fa) interact with other security controls?

Two-factor authentication (2fa) works alongside logging, network controls and endpoint protection to create layers of defence. When identity events are monitored, suspicious logins or changes become easier to spot.

What practical steps strengthen two-factor authentication (2fa) in day‑to‑day operations?

Practical steps include enforcing strong authentication, reviewing access regularly and automating joiner‑mover‑leaver processes. Clear ownership and governance around two-factor authentication (2fa) also make it more reliable.
