I’ve setup my DigitalOcean (DO) droplet so it cannot be accessed using password. However, when I replaced my local machine, I can no longer access my droplet since I’ve lost the private SSH Key. Fortunately, I can still access the remote server from Web Console, but it’s too slow and laggy.
Here’s what I do to add my current ssh key to the droplet:
1. Generate new ssh key pair in the current local machine
If there’s no ssh key pair in the local machine (
$HOME/.ssh/), generate a new one using the following command:
ssh-keygen -t rsa
Or, you can attached your email to the key using this command:
ssh-keygen -t rsa -b 4096 -C "email@example.com"
2. Save public key to another file
Use the following command to copy
cd ~ cat ~/.ssh/id_rsa.pub > key.txt
3. Upload the public key to a file sharing service
Run the following command:
curl https://bashupload.com/key.txt --data-binary @key.txt
The response will be a link to download the key. Save it to be utilize in the next step.
4. Login to DO droplet using Web Console then run these following command:
cd ~/.ssh wget <link-from-previous-step-> cat key.txt >> authorized_keys
Note: ensure to use
>> when running
cat command so the key is appended (and not overwrite) the
5. Access droplet from the new local machine
Run the following command to login to droplet through SSH:
