# 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:

1.  Zoho OneAuth
2.  OTP Authenticator
3.  Security Key
4.  Passkey

To enable MFA for your Zoho account:

*   Go to [accounts.zoho.com](http://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 unauthorized access to your account.
