I created new users from the terminal using sudo useradd -g mygroup testuser but I wasn’t prompted to set a password? why was that? the users have now been created but I need to set a password for them, so how can I do this?
Thanks
It is better to create new users with adduser instead of useradd. In this way you won't have this problem.
you can set the password with the root user after creating the user
root@yourpc:~# sudo passwd username
don't forget to run it on the root user. or you can just create your user with adduser that asks password itself.
For some reasons like -gid you might need to run the first command.
