Here is what you should pass to ssh so that it doesn’t attempt to authenticate using a Public Key.

ssh-o "PubkeyAuthentication no" user@server

I was getting the following error when trying to login to ssh to a Server.

Received disconnect from <IP>: 2: Too many authentication failures for root

I verbosed to see the errors and got the following:


debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: publickey
debug1: Offering RSA public key: bijay@bijay
debug1: Authentications that can continue: publickey,password

By Default because of the ssh config, it was trying to authenticate using Public Key (pubkey)
