How do I enable Multi-Factor Authentication for my Zoho Books account?
Zoho supports Single Sign-On (SSO), which means you can access any service with the same sign-in page and credentials. Additionally, it supports Multi-factor Authentication to add a layer of security while signing in to your accounts. The different MFA modes that are currently supported are:
- Zoho OneAuth
- OTP Authenticator
- Security Key
- Passkey
To enable MFA for your Zoho account:
- Go to accounts.zoho.com and log in with your registered email address and password. 
- Click Multi-Factor Authentication on the left sidebar to view the different MFA modes.  
- Select the MFA mode you prefer and click Set up Now. 
- Follow the instructions listed for each MFA mode to enable it for your Zoho account. 
Once you’ve set up MFA, future sign-ins will require you to verify your identity to prevent unauthorised access to your account.
