It is also more safe since there is the need of actual data present in your pc, which cannot be "guessed", unlike many passwords.%0a%0aOnce created you can log in to the shell using your username and password for the first time. In order to set up ssh-key based authentication you just need to add your public key to the authorized_keys file in the .ssh folder. %0a%0aFirst this guide will show you how to do that and in the second part there will be links on how to generate an ssh-key pair for those who want one.%0a%0a!! Part 1: Create your SSH key(pair)%0a%0aCreating SSH keys is a platform specific procedure.%0a%0aFor Windows users detailed instructions can be found at:\\%0ahttps://www.ssh.com/ssh/putty/windows/puttygen \\%0a%0aFor Linux, Mac, and Termux (Android) users detailed instructions can be found at: \\%0ahttps://www.ssh.com/ssh/keygen%0a%0aOn Linux or UNIX, ssh key pair can be generated with%0a%0a[@%0a$ ssh-keygen -t rsa%0a@]%0a%0a%0a!! Part 2: Configure SSH key(pair) access%0a%0aAssuming you are log into your shell and you see **%3cYourName>$**, press ''ls -a'' to show all the items in your home directory. Notice the **.ssh** folder, that is the one we want. Press ''cd .ssh'' to change into it and press again ls to see the **authorized_keys** file that we were looking for.%0a%0aTime to open this file for editing, one way to do this is the command ''nano authorized_keys''.
