How To Restrict Access To A Specific File In The Account Folder Rather Than The Entire Folder

I am ristrcting access to the Account folder using below:

<location path="Account">
<system.web>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
</system.web>
</location>

and access to the Default.aspx using

<location path="Default.aspx">
<system.web>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
</system.web>
</location>

but how do i restrict access to a specific file in the Account folder rather than the entire folder?

I tried the following but did not work

<location path="AccountChangePassword.aspx">
<system.web>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
</system.web>
</location>
