Removing authentication for a particular file in ubuntu

Question

Whenever I am opening a file for which content is written by a server, I am prompted with authentication. As I had to open many times, would like to remove the authentication. Can someone tell me how to remove the authentication?

Answer 1

In /etc/passwd file,
contains settings in below format

login name:optional encrypted password:numerical user ID:numerical group ID:user name or comment field:user home directory:optional user command interpreter

second parameter ie, 'optional encrypted password' setting will trigger the authentication

If this parameter is left empty, ubuntu will not prompt for authentication.
