In today’s digital world, securing your online accounts is more important than ever, and your AWS (Amazon Web Services) account is no exception. One of the best ways to safeguard your AWS account is by enabling Multi-Factor Authentication (MFA). MFA adds an additional security layer, requiring not only your password but also a second method of verification, such as a code from your smartphone, to access your account.
In this blog, we’ll learn the steps to enable MFA in AWS. Let’s dive in.

What is Multi-Factor Authentication (MFA)?
Multi-Factor Authentication (MFA) is a security feature that requires two or more methods to verify your identity. In AWS, MFA generally involves two key components:
- Something you know: Your username and password.
- Something you have: A device, such as a smartphone app, that generates a unique authentication code.
By requiring both a password and a one-time code, MFA drastically reduces the risk of unauthorized access to your AWS account, even if someone else has your password.
Why Enable MFA in AWS?
Enabling MFA in your AWS account provides several key benefits:
- Enhanced Security: Adds an extra layer of defense against unauthorized access.
- Compliance: Helps you meet security standards and regulatory requirements.
- Peace of Mind: Lowers the risk of security breaches and data theft.
MFA Device Options in AWS
AWS offers a variety of MFA device options to suit different needs:
- Virtual MFA Device: Allows multiple tokens on a single device, such as Google Authenticator (phone only) and Authy (supports multiple devices).
- Universal 2nd Factor (U2F) Security Key: Lets multiple root and IAM users share a single security key, like Yubikey by Yubico (third-party).
- Hardware Key Fob MFA Device: Provided by Gemalto (third-party) for physical token-based authentication.
- Hardware Key Fob MFA Device for AWS GovCloud (US): A specialized device provided by SurePassID (third-party) for AWS GovCloud users.
Steps to Enable MFA in AWS
1. Log in to your AWS account by clicking here.
2. In the top right corner of the navigation bar, select your account name, and then choose “Security Credentials” from the dropdown menu.
3. Now, select the Assign MFA option.
4. Enter the MFA device name and select the Authenticator app as the MFA device. Then, click “Next.”
5. Now, install the Google Authenticator app on your phone.
6. Once installed, open the Google Authenticator app, click “Get Started,” and scan the QR code.
7. Click “Show QR Code” in the AWS Console, then open the Google Authenticator app on your phone. Scan the code with your phone, and enter the generated code into the fields for MFA code 1 and MFA code 2. Once entered, click on the Add MFA button.
Tip: Take a screenshot of the code so that in the future if you lose your phone you can use it to re-enable MFA
8. You will now see that the device has been successfully added for MFA.
Accessing AWS Console Using MFA
1. Open the AWS console login page. Click on “Root User,” enter your email address, and then click “Next.”
2. Enter the password associated with your email address.
3. Open the Google Authenticator app on your phone and enter the MFA code in the AWS Console.
This overview covers how to enable and use MFA in AWS.
What if the MFA Device Doesn’t Work?
If your MFA device isn’t functioning properly, it may have fallen out of sync with AWS. To resolve this, you can try resynchronizing your virtual or hardware MFA device.
If your MFA device is lost, damaged, or stops working, you can still recover access to your AWS account. IAM users should reach out to an administrator to have the device deactivated.
Additional Tips
- Backup Codes: Some MFA apps provide backup codes that can be used if you lose access to your MFA device. Make sure to store these codes in a secure place.
- Multiple Devices: It’s a good idea to set up MFA on more than one device to prevent being locked out if your primary device is lost.
- Regular Checks: Regularly review your security settings in the IAM dashboard to ensure everything is current.
Conclusion
Enabling Multi-Factor Authentication (MFA) in AWS is a key step in securing your account from unauthorized access. By following the simple steps outlined in this guide, you can add an extra layer of security and keep your AWS resources safe. Whether you’re managing a single account or overseeing a large enterprise, MFA is an essential security feature that shouldn’t be ignored.

FAQs
Q1. What is Multi-Factor Authentication (MFA) in AWS?
Multi-Factor Authentication (MFA) in AWS is an extra layer of security that requires not only your password but also a second form of verification, such as a code from an authentication app, to access your account. This two-step process helps protect your account from unauthorized access even if your password is compromised.
Q2. What MFA device options are available in AWS?
AWS offers several MFA device options including:
1. Virtual MFA Device: Uses apps like Google Authenticator or Authy on your smartphone.
2. Universal 2nd Factor (U2F) Security Key: Physical keys like Yubikey.
3. Hardware Key Fob MFA Device: A physical token provided by third parties such as Gemalto or SurePassID.
Q3. What should I do if my MFA device stops working?
If your MFA device stops working, it might be out of sync with AWS. You can try resynchronizing the device. If the device is lost or damaged, you can recover your AWS account, and IAM users should contact an administrator to deactivate the device.
Q4. Can I set up MFA on multiple devices?
Yes, you can set up MFA on multiple devices. This is recommended as it provides a backup in case you lose access to your primary MFA device, ensuring that you’re not locked out of your AWS account.
Q5. How often should I review my MFA settings in AWS?
It’s a good practice to regularly review your MFA settings in the AWS IAM dashboard. This helps ensure that your security measures are up to date and that all devices connected to your MFA are functioning correctly.
