Hide user password input from batch file

I am creating a batch file that has a variable of setting a SQL sa password in the configuration file. 

This isn't hidden in the command view and it is show in plain text. Is there a simple way of adding this to the batch file?

Here is my code this is my first ever attempt:

 :top1
set /p SAPWD="Enter SA password: "

set /p answer="You typed %SAPWD%% is this correct?"

if /I NOT %answer%==y GOTO top1

Any suggestions?
