CoreOS ssh asks for password

March 11, 2016 1.6k views

I'm trying to set up a new coreOS install and when I try to ssh in it asks for the password. Everytime this question is asked the answer is always to use the core user instead of root but I m using core. The command I'm running

ssh core@<droplet ip>

I have another droplet that my ssh keys work with and I added those existing keys when creating my CoreOS droplet.

Thank you for your help,

Hi Greg,

You'll want to make sure that you are using an RSA keypair to log in and not a DSA keypair. That should do the trick.


  • I'm using RSA keypair and coreuser instead of root but coreos is still asking for password (ssh key is added to DO account via control panel). Here I read that You cannot, however, use the control panel to add keys to already created droplets Also I did `cat ~/.ssh/ | ssh "cat >> ~/.ssh/authorized_keys" but it still asking for password. Assuming that you can add ssh keys to existing droplets only via digitalocean API.
