Tuya integration asking for username password, not client credientials from tuya IOT platform

Added the tuya integration, and followed steps listed here. Everything on the tuya iot side works perfectly, but unfortunately, HA integration webpage is asking for username password instead of client credentials.

Sorry, i just joined and can not post more than one media

Any thoughts on how to get pas this? Needless to say, my usual tuya account and password fails to authenticate the integration.

What version of HA are you on ?

System Health

version 2021.1.5
installation_type Home Assistant Core
dev false
hassio false
docker false
virtualenv true
python_version 3.7.3
os_name Linux
os_version 5.10.63-v7l+
arch armv7l
timezone America/New_York
Home Assistant Cloud
logged_in false

can_reach_cloud_auth ok

Lovelace

That is the problem.

That is the integration since 2021.10. If you are on an older version, you have a different Tuya integration. Tuya wanted to stop that api in December 2021, but it has been postponed by 6 months.

Oh, so it is already destined to sunset? Any alternatives?

Either log in with your country, app-login and password, for the old integration

or

Update to latest HA version, and use the new integration.
