Multi-Factor Authentication (MFA)

An authentication scheme that requires more than one independent credential to verify a user's identity. In practice, this often means combining at least two different types of factors - for example, logging in with your password (something you know) and a one-time code from your phone (something you have).

‍

MFA dramatically improves security: even if an attacker steals your password, they can't log in without that second factor. It's one of the simplest, most effective measures an SMB can implement, since many services (email, banking, VPNs, etc.) offer MFA options.

Enabling MFA on all important accounts provides an extra wall of defense with minimal hassle for users.
