Add a ssh password - Yocto

I add a new password for root in yocto but it seems there is no effect :

I follow : FAQ:How do I set or change the root password - Yocto Project

I add in local.conf
INHERIT += “extrausers”
EXTRA_USERS_PARAMS = “usermod -P sierratest root;”

And i flash : yocto_wp76xx.4k.cwe
Anything else to add?

have you tried the “passwd” command?

yes, this command work, but we need to set it with yocto for production

you can see here but I don’t know if that method works or not:
