Dynamic Login Password

The dynamic login password function, namely two-factor authentication (2FA), also known as two-step verification or two-factor authentication, is a security verification process. Besides account and password authentication, you can also use the key to verify your identity for user account security.

Currently, the two-factor authentication of the Tuya Developer Platform uses a third-party authentication service: Microsoft Authenticator. After enabling the function, you need to download and bind the app to get dynamic passwords. The following describes how to enable this function.
