Yes, it is possible.
The Tuya voice skill UI business package provides a one-click fast-binding service for custom voice skills of Amazon Alexa and Google Assistant.
If you do not use this business package, you need to Bind your account (phone number or email) through Alexa,
such as on the Alexa App's "More" page --> select "Skills & Games" --> search "Smart Life" --> click "ENABLE TO USE" ;
The page will pop up "Link your smart life account with the Amazon account";
Here you need to select "Use other account", click and choose the corresponding country and enter the account in the new page, then Next Step;
On the "Choose App" page, select the App to which the account belongs, enter the account password, verify the login, authorize, return to Alexa, bind.
This process is complicated and we recommend integrating the Voice Skill UI Business Package for a one-click fast binding service for custom voice skills of Amazon Alexa and Google Assistant.
