Hello Digital Ocean,

I am César I have three droplets over Linux with password authentication, and I really like to add SSH key auth.

Today I generated my public key by putty key generator but I have not found the option to add this public key to the droplets for using ssh key auth.

I really appreciate your help

Hello @cesarfarro

So you will need to login to the server via the password authentication and paste the public key into ~/.ssh/authorized_keys on a new line

Some guides

SSH keys provide a more secure way of logging into a virtual private server with SSH than using a password alone. With SSH keys, users can log into a server without a password. This tutorial explains how to generate, use, and upload an SSH Key Pair.

Hello, cesarfarro

You can double check this tutorials on how to create and upload SSH Keys with PuTTY on Windows:

https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/create-with-putty/

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

If you’re using a SSH-client the following command with upload the keys for you and you’ll just need to enter your username password:

cat ~/.ssh/id_rsa.pub | \
ssh username@203.0.113.0 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Hope that this helps!
Regards,
Alex
