I read the posts related to this, and it seems too complicated. I wrote a try. (If you think it's okay, please support it)
@echo off
if exist M.RQM goto bn
rem llts in 0070303schj by q@251485609
@echo 12345678>M.RQM
:bn
@cls
@echo off
@echo.
@echo.
@echo.
@echo To ensure the security of user settings, this program requires administrator privileges to enter and operate!
@echo.
@echo.
@echo Enter T to exit
@echo.
@echo ------- * -------- * --------

@echo Initial password: 12345678
@echo.
SET /P SY= Please enter the administrator password:
FOR /F %%I IN (M.RQM) DO SET syq=%%I
IF "%SY%" == "%syq%" GOTO kyjr
IF "%SY%" == "CK" GOTO ckmm
IF "%SY%" == "T" GOTO :eof
@cls
@echo.
@echo.
@echo.
@echo Sorry, (the password may have been changed) you are not an administrator and cannot enter and operate!

@goto bn

@cls
@echo.
SET /P SYg= Please press any key to enter the program (if you need to change the original password, please enter XGMM):

IF not "%SYg%" == "XGMM" goto k
:xg
@cls
SET /P xmm= Please enter the new password:
@echo %xmm%>xmm.txt
SET /P cxmm= Please enter again:

@echo Password does not match!

If you simply use batch processing without handling CTRL + C, it is very easy to be aborted. So I think it is also necessary to cooperate with some applications to control the keyboard to achieve the purpose that batch processing cannot be aborted during execution.

Sweat, the file that saves the password can actually be opened with TXT. It's just that the TXT suffix was changed. Can it be changed to garbled code?

This method mainly doesn't want others to enable your program and destroy your own settings. This is just one method. As for the place and way to save the password, you can use your own brains.

I don't have high requirements for password security, and this program is exactly what I need. Thanks a lot to the original poster.

There seems to be some issues with the code. After modifying the password, when entering the password for the second time and pressing Enter, it goes back to the password modification instead of entering the execution program.

Because you didn't restart the program, the previous variables remain in the machine.

Just add some encryption casually, then output it.

@echo off
color 0a
MODE con: COLS=50 LINES=27
set ci=3
echo.
echo Notice: Three incorrect inputs will exit. Don't enter if you don't know the password~~
echo.
:1
set /p mima=Please enter the password:
if "%mima%"=="123" goto o
set /a ci-=1
if "%ci%"=="0" cls&echo.&echo ====No password and still want to come in!!!====No way!!!====&echo.&pause&echo.&exit
cls&echo.&echo You have %ci% chances left&echo.&goto 1
:o
cls&echo.
echo ============ Password correct, access granted ============

The password upstairs is of course displayed in plain text inside. On the one hand, this can be encrypted, and on the other hand, it will be very convenient for people who have low requirements for passwords.

Directly CTRL+C..
Use the automatic run in cmd, I just cmd /d
