Code:
#!/bin/bash
display()
{
  clear
  if [ -z "$choice" ] || [ "$choice" == "Y" ]
  then
    echo -e "Please enter your ID : \c"
    read user_id
    echo -e "Please enter the password : \c"
    read passwd
  else
    exit 0
  fi
}
while true
do
  display
  if [ "$user_id" == "jcs" ] && [ "$passwd" == "123" ]
  then
    echo -e "You have been successfully authenticated!"
    exit 0
  else
    echo -e "Authentication failed!"
    echo -e "Do you want to retry ? (Y or N) : \c"
    read choice
    display
  fi
done

You can beautify the display part.

bashbug

BASHBUG(1)							      bashbug								BASHBUG(1)

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--help] [--version] [bug-report-email-addresses]

DESCRIPTION

       bashbug is a utility for reporting bugs in Bash to the maintainers.

       bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor
       once you have completed the missing fields.  bashbug will notify you of any problems with the report and ask for confirmation before
       sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
       by giving a comma separated list of bug-report-email-addresses.

       If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.

OPTIONS

       --help
	      Show a brief usage message and exit.

       --version
	      Show the version of bashbug and exit.

       bug-report-email-addresses
	      Comma separated list of recipients' email addresses. By default the report is mailed to both the GNU developers and the Debian Bash
	      maintainers.

ENVIRONMENT

       DEFEDITOR
	      Editor to use for editing the bug report.

       EDITOR
	      Editor to use for editing the bug report (overridden by DEFEDITOR).

SEE ALSO

       bash(1), reportbug(1), update-alternatives(8) for preferred editor.
