Used to be able to use an SSH publickey for root to login to droplet, while using a password prompt for other users. New computer.

The server is a LAMP stack and I set it up on my old computer. Everything was running fine, was able to SSH into root without password prompt using publickey, while able to SSH into other users (Both sudo) using a password prompt and no publickey.

I’m using a new computer and had recently started the droplet back up from a snapshot, while I can SSH into root perfectly fine using a publickey (I updated it using git bash), but if I try to SSH into either of the sudo users I get the error Permission denied (publickey).

Hey friend,

We most likely disabled password login on SSH on provisioning. Check /etc/ssh/sshd_config and make sure “PasswordAuthentication” is set to yes. If not, change it and restart the SSH server.


  • Ah yep, that worked. I saw a solution a bit back while searching around that said to change that, but it was a solution for something else (first-time setup) and thus I figured didn’t apply to me (even though I did check at the time and it was no) but I changed it now and it’s working fine. Thanks!
