About Account

Multi-Factor Authentication (MFA) is a simple and effective security authentication method. It adds another layer of account protection in addition to a username and password. An MFA device, also called a dynamic password card or token, is a device that provides this type of secure authentication method.

Currently, Tencent Cloud supports two authentication methods: Virtual MFA Device and U2F Security Key.

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.

U2F, known as Universal 2nd Factor, represents an open standard designed to enhance the security of Multi-Factor Authentication (MFA). Formulated by the Fast Identity Online Alliance (FIDO), this alliance aims to improve the security of internet identity verification. Users can complete the multi-factor authentication process by plugging a U2F hardware device into the computer's USB port and tapping a button on the key.
