Let me clear few misscoception about SSH step by step.
SSH(Secure Shell) is a network protocol to connect to a remote comuputer securely over a unsecure network. Its provide a extra layer of security so that your connection to remote host remain secure.
The default port number of SSH is 22. But this can be changed to other number. If there is no port number is mentioned then we assume it is 22.
SSH is based on client-server architecture. So, for login to SSH you need a SSH client. Login from linux system is easy, you open the terminal and enter the SSH command. Login from windows is a bit tricky. You have to use a SSH client like Putyy or Bitwise SSH client.
Now you may have a basic idea of Secure Shell(SSH). Let’s dive in the world of linux and start experimenting. In next posts I will write about command to login to SSH and doing file manupulation and other system work.

Google chrome saves the passwords and when you visit the login page it Auto fill login in login fields. Its great. But when you need to use the password on some other places, It’s not let you do. It hides password behind asterisk.
To view the password either need to go to chrome://settings/passwords or use inspect element of Chrome build in developer tool.
