Debian default passwords on RK3399

Hello,

I have installed the Debian GPT available through the download page.

It looks good, however I cannot manage to connect in a terminal either as ‘root’ or as ‘firefly’ (I have tried : firefly, rockchip, 1234, empty password…)

Can someone tell me how I am supposed to log in either as root or firefly users, both in the desktop and minimal versions of Firefly’s Debian ?

Thanks

OK, I have figured out :

$ sudo su
# passwd firefly
Enter new UNIX password :
Re-enter new UNIX password :
Password updated successfully
# exit
$
