Multi-Factor Authentication (MFA) for the GST Portal is a mandatory security measure introduced in 2026 to enhance the protection of taxpayer accounts. It requires you to verify your identity with an additional authentication factor, such as an authenticator app or one-time password (OTP), in addition to your login credentials.
If you are looking for the steps to implement multi-factor authentication on the GST portal, then this guide is for you. Here we will discuss these steps in detail, thus helping you file GST returns securely.
Step-by-step guide to enable MFA on the GST portal
Below are some of the key steps that you can follow to enable MFA on the GST portal:
Step 1: Keep the required details ready
Before starting the setup, ensure you have your registered email ID and mobile number that are linked to your GST account. You will also need a smartphone if you plan to use an authenticator app. Plus, having a stable internet connection is recommended to avoid session timeouts during the process.
Step 2: Log in to the GST portal
Visit the official GST portal and log in using your username, password, and captcha. Make sure you are logging in as the primary taxpayer or authorised signatory, as MFA settings are usually managed at this level.
Step 3: Navigate to the MFA settings
From the dashboard, go to My Profile or Security Settings, depending on the updated interface in 2025. Look for the option related to Multi-Factor Authentication (MFA) or Additional Authentication.
Step 4: Choose the preferred MFA method
The GST portal typically offers more than one authentication method. You may be asked to choose between OTP-based authentication or an authenticator app. OTP-based MFA sends a one-time password to your registered mobile number. Authenticator apps like Google Authenticator, etc., generate time-based codes on your device and are more secure.
Step 5: Complete verification
Once you select the MFA method, the portal will prompt you to verify it. For OTP-based MFA, enter the OTP received on your mobile number. For authenticator apps, scan the QR code displayed on the screen and enter the generated code. This step confirms that the authentication method is correctly linked to your account.
Step 6: Confirm and activate MFA
After successful verification, the system will prompt you to confirm MFA activation. Review the details carefully and proceed. Once confirmed, MFA will be enabled for your GST portal login. You may receive an on-screen message or email confirmation indicating successful activation.
Step 7: Test the MFA-enabled login
Log out of the GST portal and log in again to ensure MFA is working properly. During login, you will now be required to enter the additional authentication code after your password. This confirms that MFA has been successfully implemented.
Step 8: Save backup and recovery options
If the portal provides backup codes or recovery options, store them securely. These will be useful if you change your mobile device or lose access to your authenticator app. Proper backup planning helps avoid delays in GST filings and compliance activities.
Who needs to enable MFA on the GST portal?
Multi-Factor Authentication (MFA) is mandatory for specific users accessing the GST Portal. The requirement applies to the following:
- Registered taxpayers, including individuals, proprietors, and businesses
- Authorised signatories linked to a GST registration
- GST practitioners accessing client accounts
- Users with access to filing returns, viewing ledgers, or submitting applications
- Businesses with multiple users managing GST compliance
Why is MFA mandatory for the GST portal
MFA has been made mandatory to strengthen the security of taxpayer data while filing their GST returns. GST accounts contain sensitive financial and compliance information, making them a target for cyber threats. Single-password logins are no longer sufficient to prevent unauthorised access.
MFA adds an extra layer of protection by verifying the user’s identity through an additional factor. This helps reduce fraud, prevent data misuse, and ensure safer digital compliance for taxpayers. Mandatory MFA also aligns the GST system with modern cybersecurity standards adopted by government platforms in India.
Conclusion
Enabling MFA on the GST portal is no longer optional. It is an essential step toward safer and more reliable digital compliance. As GST processes continue to move online, securing access to your account becomes just as important as filing returns on time. By setting up MFA early, taxpayers and professionals can avoid last-minute login issues and work with greater confidence during peak return filing periods.
