How to add ssh pub key into authorized keys??

Hi,

It sounds like you’re using the web remote console to access your Droplet. The remote console is intended for emergency access and recovery in case you are not able to log in to your Droplet via SSH. Therefore, it has limited functionality and does not support copy/paste.

We recommend using an SSH client to log in to your Droplet and manage it. Here are some tutorials that should help you do that:

• How To Connect To Your Droplet with SSH; or
• How To Log Into Your Droplet with PuTTY on Windows

For the record, you can paste in PuTTy by right-clicking anywhere on the terminal.

Hello there,

You can check our article on How to Upload an SSH Public Key to an Existing Droplet

https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/to-existing-droplet/

You can access the droplet from the DigitalOcean console and then temporary enable the PasswordAuthentication on your droplet and access the droplet with a password to upload the ssh-key.

If you haven’t created new pair of keys you’ll need to do that first.

You can enable PasswordAuthentication for your Droplet by modifying your /etc/ssh/sshd_config file. Once set to Yes restart the SSH service and connect via an SSH client for a more stable connection. You can then modify your ~/.ssh/authorized_keys file to add the appropriate public key.

This change can be made from the DigitalOcean’s console. If you’re having issues accessing the console you can then reach to our amazing support team that can help you further with this.

To enable the PasswordAuthentication follow these steps:

2. Login to the console on the DigitalOcean website.
3. Type sudo nano /etc/ssh/sshd_config
4. Change PasswordAuthentication from “no” to “yes” and save the file
5. 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
6. Login with a password
7. Type sudo nano ~/.ssh/authorized_keys
8. Paste public key text here and save the file
9. Type sudo nano /etc/ssh/sshd_config
10. Change PasswordAuthentication from “yes” to “no” and save the file
11. Log out and attempt to log back in (if using PuTTY make sure you set up auth parameters to point to your private key)

You can then upload the key using this command:

ssh-copy-id -i ~/.ssh/mykey user@droplet

Hope that this helps! Regards, Alex
