How to SSH login to your server without password ?

You need to generate SSH Key ( the private key )on your linux local computer and then update remote linux computer or server with the authorized_keys
(the public key).

1. Check if .ssh folder already exist under your home directory
(/home/user-name/.shh ).
If not create a folder .ssh

# mkdir .ssh


2. Generate or create SSH key run ssh-keygen command.

# ssh-keygen -t rsa

Press enter for all the below options to save the default settings:


-> Enter file in which to save the key (/Users/exampleuser/.ssh/id_rsa)

-> Enter passphrase (empty for no passphrase)

-> Enter same passphrase again

Now you have created the key pair.You can find all the newly generated files in your .ssh folder.

# ls

id_rsa id_rsa.pub known_hosts

you need to copy the *.pub file to your remote computer or server. Copy the file id_rsa.pub to your web server and save it as authorized_keys under

/home/user-name/.ssh/



Restart sshd.

Thats it
