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

I have the same problem, but I added an SSH key right at the start. Since I don’t have Password authentication activated I don’t think the solutions given make sense for me. I followed the instructions for creating a key and connecting via putty but I keep getting the message “PuTTY Fatal Error - Disconnected: No supported authentication methods available (server sent: publickey)”. I’m probably missing something really obvious since I’m very new to all this and most of the terminology sounds like Latin to me (progressing from the shiny.io server for the first time), but would really appreciate any pointers!
