MFA Devices

Last updated: 2020-05-08 17:32:16

    Multi-Factor Authentication (MFA) is a simple and effective security authentication method. It adds an additional layer of protection to strengthen the username and password credentials. An MFA device, also called a dynamic password card or token, is a device that enables this authentication method. Tencent Cloud currently offers two types of MFA devices: hardware MFA devices and virtual MFA devices.

    Hardware MFA Devices

    Currently, hardware MFA devices are only available for beta users.

    The figure below shows some examples of hardware MFA devices. The 6-digit dynamic authentication code displayed is updated every 30 seconds, and the serial number of the MFA device is on the back.

    Binding a hardware MFA device

    1. Log in to the Tencent Cloud Console, click the account name in the top-right corner, and click Security Settings.
    2. Go to Basic Settings > MFA Device and click Bind.
    3. Complete the identity authentication as prompted on the authentication window that pops up.
    4. Select a hardware MFA device, enter the serial number and authentication code, and bind the device as prompted.
    5. Click Submit to complete the binding of the hardware MFA device.

    Unbinding a hardware MFA device

    1. Log in to the Tencent Cloud Console, click the account name in the top-right corner, and click Security Settings.
    2. Go to Basic Settings > MFA Device and click Unbind.
    3. Click Confirm in the pop-up box.
    4. Complete the identity authentication as prompted on the authentication window that pops up.
    5. Complete the unbinding.

    Virtual MFA Device

    A virtual MFA device is an application program that generates dynamic authentication codes. It is compliant with the time-based one-time password (TOTP) standard as defined in RFC 6238. Tencent Cloud's virtual MFA devices are supported by the Tencent Cloud Assistant mini program.

    Binding a virtual MFA device

    1. Log in to the Tencent Cloud Console, click the account name in the top-right corner, and click Security Settings.
    2. Go to Basic Settings > MFA Device and click Bind.
    3. Complete the identity authentication as prompted on the authentication window that pops up.
    4. Select a virtual MFA device and bind it as prompted.
    5. Click Submit to complete the binding of the virtual MFA device.

    Unbinding a virtual MFA device

    1. Log in to the Tencent Cloud Console, click the account name in the top-right corner, and click Security Settings.
    2. Go to Basic Settings > MFA Device and click Unbind.
    3. Click Confirm in the pop-up box.
    4. On the authentication page that pops up, enter the 6-digit dynamic authentication code and click OK to complete the unbinding.
