Enabling MFA for AWS IAM User

  1. Sign in to the AWS Management Console and open the IAM console at https://console.aws.amazon.com/iam/.

  2. In the navigation pane, choose Users.

  3. In the User Name list, choose the name of the intended MFA user.

  4. Choose the Security credentials tab. Next to Assigned MFA device, choose Manage.

  5. In the Manage MFA Device wizard, choose Virtual MFA device, and then choose Continue.

    IAM generates and displays configuration information for the virtual MFA device, including a QR code graphic. The graphic is a representation of the "secret configuration key" that is available for manual entry on devices that do not support QR codes.

  6. Open your virtual MFA app. For a list of apps that you can use for hosting virtual MFA devices, see Multi-Factor Authentication.

    If the virtual MFA app supports multiple virtual MFA devices or accounts, choose the option to create a new virtual MFA device or account.

  7. Determine whether the MFA app supports QR codes, and then do one of the following:

    • From the wizard, choose Show QR code, and then use the app to scan the QR code. For example, you might choose the camera icon or choose an option similar to Scan code, and then use the device's camera to scan the code.

    • In the Manage MFA Device wizard, choose Show secret key, and then type the secret key into your MFA app.

    When you are finished, the virtual MFA device starts generating one-time passwords.

  8. In the Manage MFA Device wizard, in the MFA code 1 box, type the one-time password that currently appears in the virtual MFA device. Wait up to 30 seconds for the device to generate a new one-time password. Then type the second one-time password into the MFA code 2 box. Choose Assign MFA.

    Important

    Submit your request immediately after generating the codes. If you generate the codes and then wait too long to submit the request, the MFA device successfully associates with the user but the MFA device is out of sync. This happens because time-based one-time passwords (TOTP) expire after a short period of time. If this happens, you can resync the device.
