Including username and password in email dynamically

I am trying to figure out how to include a user's username and password in an email dynamically. I have an Access database that contains basic student information including first name, last name, username, password, email address, school and teacher. I want to query the database based on a parameter like teacher or school and then send an email to all students who meet that query. In the email I want to include the student's username and password. Here is my code:

**************
Query:
**************
<cfquery name="GetEmail_schools" datasource="#DataSource#">
  SELECT StudentID, First, Last, Email, School, Username, PCode
  FROM data
  WHERE School = '#session.School#' AND Email IS NOT NULL
</cfquery>

****************
Code to send email:
****************
 <cfmail
        Type="HTML"
        query="GetEmail_schools"
        To="#Email#"
        From="xxx@xxxx.com"
        Subject="Your login information"
        SERVER="127.0.0.1"
        PORT="25"
        >
            <p>#First#,</p>
                      <cfloop query="GetEmail_schools">
                          <cfoutput>
                            Your username is: #GetEmail_schools.Username# <br>
                            Your password is: #GetEmail_schools.Pcode#
                          </cfoutput><br>
                      </cfloop>
 
 </cfmail>
***************************
The result when I load this page is that everyone gets a list of all usernames and passwords? How do I structure my code so an email recipient only sees their username/password?

P.S. I also tried removing the <cfloop> tags and using just <cfoutput> but the result was the same.
