Today here at Arzhost, our experts discuss how we Add SSH Key to Droplet in the Digital Ocean. My Digital Ocean (DO) droplet is configured so that a password cannot be used to access it. However, since I lost the private SSH Key when I changed my local PC, I can no longer access my droplet. Thankfully, I can still connect to the remote server through Web Console, but it’s too sluggish and choppy.
I add my current ssh key to the droplet by following these steps:
1: Create a Fresh Set of SSH Keys on Your Current Local Machine.
Add SSH Key to Droplet, the following command can be used to create a new ssh key pair if there isn’t one already in the local system ($HOME/.ssh/):
keygen-ssh -t rsa
Alternatively, you can use this command to attach your email to the key:
keygen-ssh -t rsa -b 4096 -C "your email@example.com"
2: Store the Public Key in a Different File.
To copy id rsa.pub to key.txt, issue the following command to Add SSH Key to Droplet:
if (cat /.ssh/id rsa.pub > key.txt)
3: Submit the Public Key to a Service for File Sharing.
Run the command line:
curl key.txt at https://bashupload.com —data-binary
The reply will provide a download link for the key. Save it for use in the following step to Add SSH Key to Droplet.
4: Launch the Following Command after Logging in to the DO Droplet Using the Web Console:
cat key.txt >> authorized keys
Note: Use >> to guarantee that the key is appended to the authorized keys file rather than being overwritten when using the cat command.
5: Utilize the New Local Machine to Access the Droplet
To connect to a droplet via SSH, enter the following command:
Username@IP Address: ssh
