That is all about how to configure SSH public key authentication in Linux systems. ssh -i ~/.mykeys ' 'Īny other user that tries to login without SSH key, will get ssh : Permission denied (publickey). To specify a different key, pass option -i.

This will read the SSH key from the default directory. ssh ' 'Įnter passphrase for key '/home/mibey/.ssh/id_rsa': KEY PASSPHRASE Otherwise, it will just login without passphrase prompt. Now, if you attempt to login to the server, you will be prompted to enter the key passphrase if at all you had signed it with a passphrase. If the key is not saved on the default directory, you can specify the file using -i option. Now try logging into the machine, with: 'ssh ' ''Īnd check to make sure that only the key(s) you wanted were added.

usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed - if you are prompted now it is to install the new keys usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: '/home/mibey/.ssh/id_rsa.pub' Once you have generated the keys, you can install it as an authorized key on the server using the ssh-copy-id command. The key files are usually stored in the ~/.ssh directory Copy SSH Keys to Server Note that to generate SSH keys for a specific user, you need to be logged in as that user. If you need to save the key to different file, specify the file path.

NOTE that before you can configure SSH to allow public key authentication only, you need to first generate and copy the SSH keys for the user you intend to use for logging in with, lest you wont be able to copy the SSH keys nor login as that user thereafter. Next, if you try to login without user SSH public key having been copied to the target server, you will get Permission denied (publickey). See our previous article for more details. If you need to disable password authentication for a specific user, use the Match directive to define the user. # To disable tunneled clear text passwords, change to no here! That is why you can still login with the directive PasswordAuthentication set to yes and commented out. By default, SSH is configured to allow password based login. This can be done by setting the value of the PasswordAuthentication directive to no in sshd_config file. In order to explicitly allow SSH public key authentication for anyone who is logging into a Linux system, you need to disable SSH password authentication.

Configure SSH Public Key Authentication in Linux Note that when you disable password authentication for user, the only way to login is by use of SSH keys. In our previous guide, we discussed how to disable SSH password login for specific users. Logging in to a system via SSH public key is more secure as compared to password authentication. This guide presents the simplest way of how to configure SSH public key authentication in Linux server.
