I’d take a look at the guide below. It’s geared towards 14.04, though it should work on all versions as it’s not OS specific, rather, it’s Apache.

Hello all,

You can also temporary enable the PasswordAuthentication from no to yes in order to access your droplet using a password and then once you’ve entered your key to disable the PasswordAuthentication again. This way is considered more secure than uploading the key to a Dropbox in case you don’t have any other server to us.

1. Log in to the console on the DigitalOcean website.
2. Type sudo nano /etc/ssh/sshd_config
3. Change PasswordAuthentication from “no” to “yes” and save the file
4. Open a terminal on your computer and type ssh username@[hostname or IP address] or if on a Windows box use PuTTY for password login making sure authentication parameters aren’t pointing to a private key
5. Login with a password
6. Type sudo nano ~/.ssh/authorized_keys
7. Paste public key text here and save the file
8. Type sudo nano /etc/ssh/sshd_config
9. Change PasswordAuthentication from “yes” to “no” and save the file
10. Log out and attempt to log back in (if using PuTTY make sure you set up auth parameters to point to your private key)

Hope that this helps!
Regards,
Alex
