Ubuntu, how can I let a user login with a password [closed]

Question

I wanted to create a user account on my Ubuntu VM. I wanted the user to login with a password not a key. I used the sudo adduser <username> command. It prompted me for the password and to re-type the password.

When I login with another account (which uses an ssh key), and then use su to switch user I can do it by entering the password.

But when I try to login (from my mac) I do this:

ssh <username>@<ipaddress>

and when prompted for the password I enter it, but I get the message permission denied

Any help much appreciated.

Modify /etc/sshd_config and change:

to

PasswordAuthentication yes

and run

killall -1 sshd
