- To enable SSH password authentication, you must SSH in as root to edit this file: /etc/ssh/sshdconfig. Then, change the line. PasswordAuthentication no. PasswordAuthentication yes. After making that change, restart the SSH service by running the following command as root: sudo service ssh restart Enable Logging In as root.
- For Windows OpenSSH, the only available authentication methods are 'password' and 'publickey'. The default is '.ssh/authorizedkeys.ssh/authorizedkeys2'. If the path is not absolute, it is taken relative to user's home directory (or profile image path).
You can login to a remote Linux server without entering password in 3 simple steps using ssky-keygen and ssh-copy-id as explained in this article.
ssh-keygen creates the public and private keys. ssh-copy-id copies the local-host’s public key to the remote-host’s authorized_keys file. ssh-copy-id also assigns proper permission to the remote-host’s home, ~/.ssh, and ~/.ssh/authorized_keys.
This article also explains 3 minor annoyances of using ssh-copy-id and how to use ssh-copy-id along with ssh-agent.

This article also explains 3 minor annoyances of using ssh-copy-id and how to use ssh-copy-id along with ssh-agent.
Step 1: Create public and private keys using ssh-key-gen on local-host
Step 2: Copy the public key to remote-host using ssh-copy-id
Ssh USERNAME@IP-ADDRESS ssh [email protected] It will ask “Are you sure you want to continue connecting” - type “yes” - then press enter - It will ask password, you need to copy from.
Note: ssh-copy-id appends the keys to the remote-host’s .ssh/authorized_key.
Step 3: Login to remote-host without entering the password

The above 3 simple steps should get the job done in most cases.
We also discussed earlier in detail about performing SSH and SCP from openSSH to openSSH without entering password.
If you are using SSH2, we discussed earlier about performing SSH and SCP without password from SSH2 to SSH2 , from OpenSSH to SSH2 and from SSH2 to OpenSSH.

Using ssh-copy-id along with the ssh-add/ssh-agent
![Ssh server password manager Ssh server password manager](/uploads/1/3/7/4/137473822/271748928.png)
When no value is passed for the option -i and If ~/.ssh/identity.pub is not available, ssh-copy-id will display the following error message.
If you have loaded keys to the ssh-agent using the ssh-add, then ssh-copy-id will get the keys from the ssh-agent to copy to the remote-host. i.e, it copies the keys provided by ssh-add -L command to the remote-host, when you don’t pass option -i to the ssh-copy-id.
Three Minor Annoyances of ssh-copy-id

Connect sonarlint to sonarqube. Following are few minor annoyances of the ssh-copy-id.
- Default public key: ssh-copy-id uses ~/.ssh/identity.pub as the default public key file (i.e when no value is passed to option -i). Instead, I wish it uses id_dsa.pub, or id_rsa.pub, or identity.pub as default keys. i.e If any one of them exist, it should copy that to the remote-host. If two or three of them exist, it should copy identity.pub as default.
- The agent has no identities: When the ssh-agent is running and the ssh-add -L returns “The agent has no identities” (i.e no keys are added to the ssh-agent), the ssh-copy-id will still copy the message “The agent has no identities” to the remote-host’s authorized_keys entry.
- Duplicate entry in authorized_keys: I wish ssh-copy-id validates duplicate entry on the remote-host’s authorized_keys. If you execute ssh-copy-id multiple times on the local-host, it will keep appending the same key on the remote-host’s authorized_keys file without checking for duplicates. Even with duplicate entries everything works as expected. But, I would like to have my authorized_keys file clutter free.
