Multi-factor authentication (MFA) means you need at least two pieces of information to log in to a device or an app. Perhaps a password plus a fingerprint, and possibly an extra, single-use code sent to your phone.

All businesses should be using MFA as it provides great protection against cyber-attacks and other security threats. Our new free guide tells you all you need to know.
