It’s a common error to accidentally set the PasswordAuthentication value to yes but PermitRootLogin to no or without-password when logging in as root.Įnsure that the appropriate configuration for your login method is set, then restart the service. If the message doesn’t include the authentication method you want to use, take a look at the /etc/ssh/sshd_config configuration file. If you use verbose SSH client output or logging, check that the message outlining authentication methods includes password and/or publickey in the list: debug1: Authentications that can continue: publickey,password Solutions Checking Available Authentication Methods If the problem persists after resetting the Droplet’s password, consider using the recovery environment to prepare your data for re-deployment or attempt to resolve the issues with the PAM configuration or file system. You can attempt to log in again using the console after a password reset. However, if the session restarts after entering the same new password twice (meaning you get sent back to the login prompt), it typically means that there is a problem with one of the critical files managing your authentication data. On success, you are then prompted to enter the new password twice: Enter new UNIX password: If your connection closes immediately, then you may have made a mistake re-entering the current password, so try again. This would also impact attempts to reset the root password and log in through the console.įrom the console, you’ll see this login prompt: Ubuntu 14.04.4 LTS server tty1īut when you enter the correct password, you might get this error: Login incorrectĪfter a password reset, you’ll receive a prompt like this: You are required to change your password immediately (root enforced) If you cannot recover access to the console, this could indicate issues with the file system used for authentication or configuration issues within the PAM subsystem. You’ll need to update the server configuration to allow this key type. This commonly impacts OpenSSH 7+ servers (like our FreeBSD image) when using a private SSH DSA key. You may be using a private key that is no longer supported on the OpenSSH service. ![]() Check that your public key is added to the Droplet. Make sure the authorized_keys file contains the matching public key.If you’re using an OpenSSH client, be sure your private SSH key has the proper permissions. PuTTY, make sure your SSH keys are properly configured for the session. Make sure the private key is readable by the SSH client.Check that key-based authentication is allowed by the server.Make sure the authorized_keys file and the private key itself have the correct permissions and ownership.Here are some steps you can take to troubleshoot this issue: Many of the most common issues regarding key-based authentication are caused by incorrect file permissions or ownership. You might see an error like this: Permission denied (publickey).ĭisconnected: No supported authentication methods available (server sent: publickey) You can enable password authentication in the SSH service configuration file once you successfully log in with your SSH key. When you create a Droplet with SSH keys, SSH keys are the only authentication method supported. Learn more about how SSH keys work in SSH Essentials. This login method uses cryptographic keys to authenticate a user. Check that password authentication is allowed by the server.If it doesn’t, attempt a password reset or focus on recovering your data instead. User password authentication could be broken, so check if the Recovery Console supports password login.Make sure you’re using the right username.This indicates that authentication has failed and can be caused by a number of issues. "Too many authentication failures for root" ![]() ![]() You might see these errors in both PuTTY and OpenSSH clients when attempting to log in to a Droplet with a password: 's password: If you assigned an SSH key when creating your Droplet, PasswordAuthentication is disabled for your Droplet and you need to use your SSH key to log in.
