In this post, I’ll tell you, how to create new user in Ubuntu 14.04 and how you disable user password login.
Create new user, in my e.g. it’s
example-user. Set strong password, and fill fields.
$ sudo adduser example-user
SSH key login
Now you’re created new user. In second step, we have to generate new ssh key (if you don’t already had it).
And use default value for:
Generating public/private rsa key pair. Enter file in which to save the key (~/.ssh/id_rsa):
Next we need to copy our ssh key into example-user’s authorizies keys file (~/.ssh/authorized_keys).
$ ssh-copy-id [email protected]
If you got next lines, you’re permit login to example-user by ssh key.
Number of key(s) added: 1 Now try logging into the machine, with: "ssh '[email protected]'" and check to make sure that only the key(s) you wanted were added.
Disable user password login
It mean that, you’re not longer need password to login
example-user. So if we don’t any more need password to login our new user, we could disable password login to that user.
$ sudo usermod -L example-user
