Universal 2nd Factor (U2F) security keys are a type of multi-factor authentication (MFA) device that you can use to protect and secure your resources when using an Alibaba Cloud Resource Access Management (RAM) user. U2F is a widely accepted MFA protocol that provides an efficient and universal MFA method.
One of the main differences between U2F and hardware MFA is that with U2F, you need to plug your U2F security key into a USB port on your computer and tap it when prompted to complete the sign-in process securely. You don't need to introduce any code or password.
Note : You can enable only one type of MFA device for a RAM user at the same time. Therefore, you have to choose whether you prefer to use a Virtual device or a U2F device.
The following step-by-step guide explains how to enable U2F security keys on Alibaba Cloud. In this tutorial, we used Yubikey 5c produced by Yubico as the U2F Security Key.
Note: You need to use your Alibaba Cloud account or a RAM user that has administrative rights.

If you want to disable the U2F Security Key, follow the steps below:
