This code was written by someone else. My idea is:
if the BB.txt file does not exist, then display a prompt (if it exists, then run the password verification program according to bb.txt)
For first-time use, please set a password:
Then save it to BB.txt
When running the program again next time

@echo off
if exist bb.txt goto next
set /p password=For first-time use, please set a password:
echo.%password%>bb.txt

:next
for /f "delims=" %%i in (bb.txt) do set passwords=%%i
:begin
cls&set /p password= Please enter the password:
...

Does the part from :set to :wrong have any chance to execute?

Can someone write code based on the above idea that can set a password and change a password?

Change:
if "%password%"=="%passwords%" goto ok
to:
if "%password%"=="%passwords%" goto set

@echo off if exist %windir%\bb.txt goto check_pass set /p password=Please set a password:&echo %password%>%windir%\bb.txt&goto opration_ver :check_pass for /f "delims=" %%i in (%windir%\bb.txt) do set passwords=%%i cls&set /p password=Please enter the password: if "%password%"=="%passwords%" goto opration_ver cls&echo Wrong password&ping /n 2 127.1>nul&goto check_pass

Everyone help me take a look, with the code above, after setting the password the content written to bb.txt is: ECHO is off.
Where exactly is the problem?

:set_pass cls&set /p New_pass=Please enter the new password: cls&set /p New_pass1=Please enter the new password again: if %New_pass% equ %New_pass1% echo %New_pass%>bb.txt&echo.Set successfully&pause&goto ok echo.The two passwords entered do not match, please set it again&pause&goto set_pass :ok cls&echo Correct password!&pause&goto :eof

This is the code for changing the password. Everyone take a look, is this okay?

@echo off if exist M.RQM goto bn rem llts in 0070303schj by qq251485609 @echo 12345678>M.RQM :bn @cls @echo off @echo. @echo. @echo. @echo For the security of the user's settings, only the administrator can enter operations in this program! @echo. @echo. @echo Enter T to exit @echo. @echo ------- * -------- * -------- @echo. @echo Initial password: 12345678 @echo.

Thanks, ZJHJ.
What I wanted was: if the M.rqm file does not exist, then prompt the user to set a password; if it exists, then use the contents of M.Rqm to verify the password. I've already solved the problem, thanks.
