Introduction to MFA

Introduction to MFA

Multi-factor authentication is used as an extra layer of security while signing in to your account. When you enable MFA, all your future sign-ins will require you to verify your identity to ensure that your account isn't accessed by unknown users. You can do this by enabling MFA mode. For example, if you enable SMS-based OTP, then an OTP will be sent to your mobile number, which then needs to be entered when you sign in, thus ensuring that your account stays protected.
Zoho provides four authentication modes to choose from.

OneAuth 

OneAuth is an industry standard multi-factor authentication app built by Zoho. It offers MFA for all your Zoho accounts, passwordless verification, mobile SSO, easy backup and recovery, and OTP authentication for non-Zoho accounts.

SMS-based OTP  

When you set SMS-based OTP as your MFA mode, a short-lived, single-use authentication code is sent to your mobile device as an SMS message, which you can use to verify your identity during sign-in.  

OTP authenticator 

An OTP authenticator generates unique codes in fixed time intervals. When you set an OTP authenticator as your MFA mode, you can use the OTP shown in the authenticator app to verify your identity during sign-in.

YubiKey  

A YubiKey is a hardware device which can be inserted into your computer or laptop. When you configure a YubiKey for your account and set it as your MFA mode, you can insert it to verify your identity during sign-in.

How to enable MFA for your account 

  1. Sign in to your Zoho account.
  2. Click Multi-Factor Authentication.
  3. Use the toggle bar in the top-right corner to enable MFA.
  4. Select your preferred MFA modes. 
If you enable multiple MFA modes, one of them will be set as your primary mode, and will be used as the default mode for all your future sign-ins.
You can also enable more than one MFA mode for your account, referred to as multi-mode MFA. This comes in handy if your primary mode isn't available when you sign in.
