I followed the tutorial for setting up myself with SSH login which worked fine. I have another user I need to add as well but I am not sure how to go about doing that. I have his public key and added it to the droplet on creation. Droplet is running ubuntu 18.04. Any help would be greatly appreciated. I’ve looked through several other tutorials and documentation for this as well but I just can’t seem to find exactly what I am looking for. I don’t think I can set him up the same way I set it up for myself.

Hi @rconover,
You’ll need to create a new user and add the SSH keys there. I normally set and create their home directory at the same time.
i.e.
Create Home Directory + .ssh Directory
Create Authorized Keys File
Create User + Set Home Directory
Add User to sudo Group
Set Permissions
Set Password on User
If you want to be able to log in as the user without an SSH key, setting a password will allow that, as long as PasswordAuthentication is enabled in
/etc/ssh/sshd_config.…
You can check the users home directory by running:
… while logged in as the user. If you echo
$PWD, it’ll give you the current path to the directory that you’re currently in. So if I rancd /home, running:… will give me
/home. If my home directory is/home/mynewuser, then$HOMEwill give me that directory :-).…

Thank you very much! That clarifies a few things for me. I greatly appreciate it KFSys.
Happy to help!
After all, this Q/A section is exactly for this!
I don’t see why you would
chown root:root /home/mynewuserBy default, the commanduseradd mynewusermakes mynewuser the owner and group of the /home/mynewuser directory, which seems like a sensible default. Otherwise, you’ll need to add the execute bit to the permissions on /home/mynewusers in order for the authorized_keys file or any others to be accessible, which seems less ideal for security.@kfsys
Omit this step on Ubuntu 22.04
I could not ssh in to the server because of this - error: Public key access denied.
Hi there,
I followed the steps listed above by KFSys and it looks like everything worked properly but when I tried to use the user&pass inside the Jetpack backup settings, it’s saying that the connection fails. Any thoughts?
Besides that, I’m using Transmit (file transfer tool) and after the steps above I cannot connect to the server with the root user anymore :PANIC:
Hi @diegobechi,
Using the above to create your SSH key you shouldn’t be asked for a password.
If you however decided to use a password you need to enable it in your /etc/ssh/sshd_config. In there you’ll find the
PasswordLogin and set it to Yes.
Additionally, if you’ve lost access to your Droplet, check the following docs:

Hi, @rconover
You can check out our existing tutorial on how to add users on Ubuntu 18.04 here:
https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-ubuntu-18-04
Additionally you can check that the user’s ssh key is present in the
~/.ssh/authorized_keysfile and if not to add it there.If the user needs a sudo access you can grant him access by following the tutorial.
Hope that helps!

Hi,
I’ve created a new user on 18.04 and .ssh folder has been created together with authorized_keys file.
I want to access it with Putty but it says "no supported authentication methods available (server sent: publickey).
I need that for Jetpack. I’m accessing the droplet with my SSH private key, no username is used.
How can I make this happen?
Hello, @smailmilak
I will recommend you to check our existing tutorial on how to connect to your droplet using PuTTY on Windows.
https://www.digitalocean.com/docs/droplets/how-to/connect-with-ssh/putty/
and also on how to create ssh keys with PuTTY and Connect to a VPS:
https://www.digitalocean.com/community/tutorials/how-to-create-ssh-keys-with-putty-to-connect-to-a-vps
Hope that this helps! Regards, Alex
Hi, so I managed to do that with PuttyGen. It’s easy if you what you are doing :)
So, now I want to give Jetpack RW access to /var/www/html/ where the Website files are located for Backup (I have digitalocean backup as well).
Problem is that this new user has R/O access only.
What is the exact chmod command to give R/W access to user ‘jetpackuser101’ and folder /var/www/html/ without breaking something?
Well, the folder needs to have 755 permissions to have Read/Write access. That should be all.
