Configure SSH login without Password

Step 1:

> ssh-keygen -t rsa

Enter to generate id_rsa.pub and id_rsa

Check the private and public key generated in ~/.ssh/ folder

Step 2:

>ssh-copy-id -i ~/.ssh/id_rsa.pub username@remotehost

while doing this step, you have to enter the password

 
For Eg: ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.168.26
root@192.168.168.26's password:
Now try logging into the machine, with "ssh 'root@192.168.168.26'", and check in:~/.ssh/authorized_keysto make sure we haven't added extra keys that you weren't expecting.

Step 3:

ssh username@remotehost
 

Now it will login without password
