How to fix putty error: "Putty fatal error: No supported authentication methods available (server sent: public key)"

Posted on October 9, 2019

I am using a new droplet with Ubuntu, and have Windows and Putty on my local machine…For setting up ssh I am following: https://www.digitalocean.com/docs/droplets/how-to/connect-with-ssh/putty/ and choosing the option to skip over “specify an ssh key…” and use login and password instead, but I get the error: “Putty fatal error: No supported authentication methods available (server sent: public key)”. I do not see any posted solutions which do not involve setting up an ssh key.
