Security Policies - Configure MFA | Admin Guide - Zoho One

Configure MFA

Multi-factor authentication (MFA) adds an additional layer of security to your organization. When MFA is enabled, your users will have to verify their identity not only with their password, but also with a second factor. The second factor could be an authenticator app like  Zoho OneAuth, a hardware security key (YubiKey), or an SMS-based OTP.

When MFA is enabled for a user, they will not be able to sign in without setting up their preferred authentication mode and verifying themself. You can configure the list of MFA modes your users can choose from.
