Question

Dont work, Add SSH keys after Droplet created

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

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

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
