Pretty good first try.

Code:
#!/bin/bash
secretname=secret
name=noname
echo "try to guess the password."
TRY=0
echo
until [ "$name" = "$secretname" ] || [ "$TRY" -ge 5 ]
do
        echo -n "your guess: "
        read name
        ((TRY++))
done

if [ "$name" = "$secretname" ]
then
        echo "You guessed!"
else
        echo "Fail"
fi

NAME

       systemd-tty-ask-password-agent - List or process pending systemd password requests

SYNOPSIS

       systemd-tty-ask-password-agent [OPTIONS...] [VARIABLE=VALUE...]

DESCRIPTION

       systemd-tty-ask-password-agent is a password agent that handles password requests of the system, for example for hard disk encryption
       passwords or SSL certificate passwords that need to be queried at boot-time or during runtime.

       systemd-tty-ask-password-agent implements the Password Agents Specification[1], and is one of many possible response agents which answer to
       queries formulated with systemd-ask-password(1).

       The following options are understood:

       --list
	   Lists all currently pending system password requests.

       --query
	   Process all currently pending system password requests by querying the user on the calling TTY.

       --watch
	   Continuously process password requests.

       --wall
	   Forward password requests to wall(1) instead of querying the user on the calling TTY.

       --plymouth
	   Ask question with plymouth(8) instead of querying the user on the calling TTY.

       --console
	   Ask question on /dev/console instead of querying the user on the calling TTY.

       -h, --help
	   Print a short help text and exit.

       --version
