Set root password back to empty [beaglebone black]

Hello, i have a beaglebone black and i’ve changed the root password.
I bought a touchscreen lcd’4 cape but i can’t login with it, no virtual keyboard appears when i click on the login “password” field.

I want to set the root password back to empty, i tried via ssh to do “passwd” and just type enter twice but it didn’t work out, any tips for me to be able to login to my bbb with the cape ?:slight_smile:

This is the cape i’ve bought:

I would set it up to get the virtual keyboard you need and not set a
blank password.

And hwo can i do it ?:slight_smile:

Type “passwd -d” to delete the password.

The command is actually
passwd -d root
