# What is Multi-Factor Authentication (MFA) and how do I enable it for my Zoho Invoice account?

Zoho supports Single Sign-On (SSO), which means you can access any service with a single sign-in and credentials. Additionally, it supports Multi-factor Authentication that adds a layer of security while signing in to your accounts. The different MFA modes that are currently supported are **Zoho OneAuth and Security Key.**

To enable MFA for your Zoho account:

*   Go to [accounts.zoho.com](https://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 the MFA mode you selected 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.
